This is a proposed rule (not final) that would fully remove ATF’s 2023 “stabilizing brace” rule and return to the pre-2023 definition of “rifle” based only on the statute.

Impact: Very high—effectively ends the brace rule and removes NFA treatment for most braced firearms (unless they independently meet the statutory definition).

Applies to: Both individuals and the firearms industry (FFLs).What this rule means is that ATF is proposing to undo its 2023 stabilizing brace rule after multiple courts found it unlawful and blocked its enforcement.

Key reasons:

  • Courts ruled the rule was likely arbitrary and capriciousThe rule created confusion and unclear standardsATF acknowledges the “multi-factor test” was difficult to apply

So instead of trying to fix it, ATF is:

  • Removing the rule entirely
  • Returning to the plain statutory definition of “rifle”
  • Going back to case-by-case classification decisions

What the rule actually does. If finalized, this rule would:

1. Delete the 2023 brace rule language

  • Removes the added factors used to determine if a firearm with a brace is a rifle
  • Eliminates the “designed to be fired from the shoulder” expanded interpretation

2. Restore the original definition of “rifle”

  • Returns to the statutory definition only:
    • A firearm designed and intended to be fired from the shoulder
  • No additional ATF-created tests or factors

3. End the “factor-based” classification system

  • No more:
    • Weight/Length Comparisons
    • Length-of-pull Measurements
    • Marketing Analysis
    • “Community Use” Analysis

4. Return to case-by-case determinations

  • ATF will evaluate firearms individually based on:
    • Design
    • Function
  • Without a rigid checklist or scoring system

What will change (real-world impact)

For Individuals (Major Impact):

  • Most firearms with stabilizing braces will:
    • No longer be treated as NFA items
    • No longer require registration, fingerprints, nor approval
  • You can:
    • Buy and own braced firearms similar to pre-2023 practices
  • Estimated Impact:
    • Millions of firearms (ATF estimates up to ~7 million in circulation)

For FFLs / Industry (Major Impact):

  • Manufacturers and retailers can:
    • Resume normal production and sales of braced firearms
  • Reduced compliance burden:
    • No NFA classification for most braced firearms
  • Significant Economic Effect:
    • ATF estimates ~$144 million/year in savings from avoided NFA compliance costs

For the system overall:

  • Major rollback of a high-profile ATF rule
  • Reinforces limits on:
    • Agency-created multi-factor tests without clear statutory backing
  • Reintroduces:
    • Some uncertainty (no bright-line rules)
  • Bur reduces:
    • Overly complex and vague regulatory standards

Important caveat:

  • This does NOT mean all braced firearms are automatically legal under NFA
  • If a firearm is:
    • Actually designed to be fired from the shoulder → still a rifle/SBR
  • Determination becomes:
    • Fact-specific, not checklist-based

Key Takeaways:

  • Fully removes the 2023 stabilizing brace rule
  • Returns to simple statutory definition of “rifle”
  • Eliminates confusing multi-factor analysis
  • Major deregulatory impact for industry and consumers
  • Shifts back to case-by-case determinations

Removing Factoring Criteria for Firearms with Attached “Stabilizing Braces”

AGENCY: Bureau of Alcohol, Tobacco, Firearms, and Explosives, Department of

Justice.

ACTION: Notice of proposed rulemaking.

SUMMARY: The Bureau of Alcohol, Tobacco, Firearms, and Explosives (“ATF”) is

proposing to amend Department of Justice (“Department”) regulations on firearms with

attached stabilizing braces. Courts have found that ATF’s revisions in the 2023 final rule

on the same topic violated the Administrative Procedure Act. Several courts have

enjoined, stayed, or vacated the final rule, which has rarely been in effect. ATF is

therefore proposing to remove from the regulatory definitions of “rifle” the two

paragraphs added by the 2023 final rule that defined the term “designed or redesigned,

made or remade, and intended to be fired from the shoulder.”

SUPPLEMENTARY INFORMATION:

I. Background

The Attorney General is responsible for enforcing the Gun Control Act (“GCA”),

as amended, and the National Firearms Act (“NFA”), as amended.1 This includes the

authority to promulgate regulations necessary to enforce the provisions of the GCA and

NFA. See 18 U.S.C. 926(a); 26 U.S.C. 7801(a)(2)(A)(ii), 7805(a). Congress and the

Attorney General have delegated the responsibility for administering and enforcing the

GCA and NFA to the Director of ATF (“Director”), subject to the direction of the

Attorney General and the Deputy Attorney General. See 28 U.S.C. 599A(b)(1), (c)(1); 28

CFR 0.130(a)(1)–(2); Treas. Order No. 221(2)(a), (d), 37 FR 11696–97 (June 10, 1972).2

Accordingly, the Department and ATF have promulgated regulations implementing both

the GCA and the NFA in 27 CFR parts 478, 479. ATF’s Firearms and Ammunition

Technology Division (“FATD”), Office of Enforcement Programs and Services (“EPS”),

classifies firearms pursuant to the GCA and NFA. FATD supports the firearms industry

and the general public by, among other things, responding to technical inquiries and by

testing and evaluating firearms voluntarily submitted to ATF for classification under

1 Some NFA and GCA provisions still refer to the “Secretary of the Treasury.” However, the Homeland

Security Act of 2002, Pub. L. 107–296, 116 Stat. 2135, transferred the functions of ATF from the

Department of the Treasury to the Department of Justice, under the general authority of the Attorney

General. 26 U.S.C. 7801(a)(2); 28 U.S.C. 599A(c)(1). Thus, for ease of reference, this proposed rule refers

to the Attorney General where relevant.

2 In Attorney General Order Number 6353–2025, the Attorney General delegated authority to the Director

to issue regulations pertaining to matters within ATF’s jurisdiction, including under the NFA, GCA, and

Title XI of the Organized Crime Control Act. ATF’s jurisdiction also includes those portions of sec. 38 of

the Arms Export Control Act pertaining to permanently importing defense articles and services and the

Contraband Cigarette Trafficking Act.federal law.

Firearms are treated differently under the GCA and the NFA. Congress passed the

NFA to regulate certain weapons that were viewed as especially adaptable to criminal

misuse. As a result, NFA firearms must be registered with ATF. 26 U.S.C. 5811, 5821,

5841, 5845. Additionally, NFA firearms were generally subject to special making and

transfer taxes. However, the One Big Beautiful Bill Act became law on July 4, 2025, and

it amended the NFA to require that the making and transfer taxes for all NFA firearms,

other than machine guns and destructive devices, be reduced to $0 effective January 1,

2026. A weapon classified as a “firearm” under only the GCA is not subject to transfer

taxes or additional registration, even though it is still subject to record-keeping

requirements, serialization, interstate controls, and potential taxation under 26 U.S.C.

4181. Because of these differences, it matters a great deal whether a firearm falls under

the NFA.

One kind of firearm covered by the NFA is “a rifle having a barrel or barrels of

less than 16 inches in length,” or “a weapon made from a rifle if such weapon as

modified has an overall length of less than 26 inches or a barrel or barrels of less than 16

inches in length.” 26 U.S.C. 5845(a)(3), (a)(4). Therefore, determining whether a firearm

falls under the NFA sometimes turns on whether a firearm is classified as a “rifle.”

The GCA defines “rifle” as “a weapon designed or redesigned, made or remade,

and intended to be fired from the shoulder and designed or redesigned and made or

remade to use the energy of an explosive to fire only a single projectile through a rifled

bore for each single pull of the trigger.” 18 U.S.C. 921(a)(7). Similarly, the NFA defines

“rifle” as “a weapon designed or redesigned, made or remade, and intended to be fired

from the shoulder and designed or redesigned and made or remade to use the energy of

the explosive in a fixed cartridge to fire only a single projectile through a rifled bore for

each single pull of the trigger, and shall include any such weapon which may be readilyrestored to fire a fixed cartridge.” 26 U.S.C. 5845(c). For a long time, ATF’s regulations

incorporated these different statutory definitions. See 27 CFR 478.11; 27 CFR 479.11.

On November 8, 2012, a federal firearms licensee submitted the first firearm

‘‘stabilizing brace’’ to ATF, asking if adding its prototype device to a heavy pistol, such

as an AR-type pistol, would change the pistol’s classification to a rifle under federal

firearms laws. The submitter described the brace device as designed to assist people with

disabilities or limited strength or mobility in firing heavy pistols safely and comfortably.

FATD ultimately concluded that attaching the brace would not alter the classification of a

pistol or other firearm and thus would not subject them to the provisions of the NFA. In

the years following this initial classification, FATD received a number of inquiries

regarding other firearms equipped with braces of varying designs and materials, some of

which FATD concluded were “rifles.”

On June 10, 2021, ATF issued an NPRM seeking to clarify and define “rifle” to

include pistols with an attached ‘‘stabilizing brace’’ if the weapon ‘‘has objective design

features and characteristics that facilitate shoulder fire,’’ as indicated on ATF Worksheet

4999.3 ATF received over 237,000 comments on the NPRM, many of which criticized the

proposed ATF Worksheet 4999 as being too confusing and unnecessarily complex.

On January 13, 2023, the Attorney General signed ATF Final Rule 2021R-08F,

“Factoring Criteria for Firearms with Attached ‘Stabilizing Braces’” (“2023 final rule”).

The 2023 final rule did not adopt the proposed Worksheet 4999, but it outlined the factors

ATF would consider when evaluating firearms equipped with a “stabilizing brace” (or

other rearward attachment) to determine whether these weapons would be considered a

“rifle” or “short-barreled rifle” under the GCA, or a “rifle” or “firearm” subject to

regulation under the NFA. The 2023 final rule was published in the Federal Register.

4

See 86 FR 30826.

See Factoring Criteria for Firearms With Attached “Stabilizing Braces,” 88 FR 6478 (Jan. 31, 2023).Those possessing firearms with a stabilizing brace that were considered short-barreled

rifles under the 2023 final rule, and thus subject to the registration requirements of the

NFA, had until May 31, 2023, to register the firearm tax free.

Specifically, the 2023 final rule amended definition of “rifle” in 27 CFR 478.11

and 479.11 to provide that the term “designed, redesigned, made or remade, and intended

to be fired from the shoulder” includes a weapon that is equipped with an accessory,

component, or other rearward attachment (e.g., a “stabilizing brace”) that provides

surface area allowing the weapon to be fired from the shoulder, provided other factors, as

listed in the definition, indicate the weapon is designed and intended to be fired from the

shoulder. These other factors are: (1) whether the weapon has a weight or length

consistent with the weight or length of similarly designed rifles; (2) whether the weapon

has a length of pull, measured from the center of the trigger to the center of the shoulder

stock or other rearward accessory, component or attachment that is consistent with

similarly designed rifles; (3) whether the weapon is equipped with sights or a scope with

eye relief that require the weapon to be fired from the shoulder in order to be used as

designed; (4) whether the surface area that allows the weapon to be fired from the

shoulder is created by a buffer tube, receiver extension, or any other accessory,

component, or other rearward attachment that is necessary for the cycle of operations; (5)

the manufacturer’s direct and indirect marketing and promotional materials indicating the

intended use of the weapon; and (6) information demonstrating the likely use of the

weapon in the general community. Those affected by the 2023 final rule who did not

want to register their firearms were given the following options: (1) remove the short

barrel and attach a 16-inch or longer rifled barrel to the firearm; (2) permanently remove

and dispose of, or alter, the “stabilizing brace” such that it cannot be reattached; (3) turn

the firearm into the local ATF office; or (4) destroy the firearm.5

Id.Within weeks of the 2023 final rule’s effective date, several lawsuits had been

filed, all of which alleged violations of the Administrative Procedure Act (“APA”). In

several of these lawsuits, United States District Courts in Texas granted motions to

preliminarily enjoin the 2023 final rule.6 The Eighth Circuit and the United States District

Court for the Middle District of Florida also enjoined ATF from enforcing the final rule,

and the Northern District of Texas ultimately vacated the final rule in its entirety in

June 2024. In short, the 2023 final rule was preliminarily enjoined in multiple

jurisdictions prior to the vacatur on the merits in June 2024.

The Fifth Circuit. In the Northern District of Texas, William T. Mock, Maxim

Defense Industries, LLC, and the Firearms Policy Coalition, Inc., moved to preliminarily

enjoin the 2023 final rule. On March 30, 2023, the district court denied the motion for

preliminary injunction.7 The plaintiffs appealed the order to the Fifth Circuit, and on May

23, 2023, a motions panel of the Fifth Circuit issued an injunction pending appeal of the

2023 final rule as to the plaintiffs.8 Other district courts in Texas soon followed suit and

granted preliminary injunctions to additional plaintiffs pending the Mock appeal.9 By

mid-June 2023, ATF was preliminarily enjoined from enforcing the 2023 final rule as to

two manufacturers and their customers, four nationwide advocacy groups and their

members, one state’s employees and agencies, and eight individuals.10 On August 1,

2023, the Fifth Circuit reversed the district court’s denial of a preliminary injunction in

Mock, held that the plaintiffs were likely to prevail on the merits, and remanded the case

to the district court.11 The district court subsequently entered a preliminary injunction as

Northern District of Texas universally stayed the 2023 final rule under 5 U.S.C. 705 in its

entirety nationwide.12 Several months later, on June 13, 2024, the district court in Mock

granted the plaintiffs’ motion for summary judgment, denied the Government’s motion

for summary judgment, and universally vacated the final rule. On August 26, 2024, the

Fifth Circuit dismissed all pending appeals regarding preliminary injunctions in Texas

district courts as moot after the June 13, 2024, decision in Mock.

13

The Eleventh Circuit. On January 26, 2024, the Middle District of Florida granted

a preliminary injunction that has effectively prevented the Government from enforcing

the 2023 final rule against the named plaintiffs and past and future customers of the

plaintiffs residing in Florida.14 The district court found there would be irreparable harm to

plaintiffs challenging the 2023 final rule and that the final rule likely violated the APA’s

notice and comment requirement.15

The Eighth Circuit. On August 9, 2024, the Eighth Circuit, considering an appeal

of a denial of a preliminary injunction, found that plaintiffs challenging the 2023 final

rule were likely to succeed on the merits and remanded the case to the district court with

instruction to reconsider the motion, consistent with the court’s opinion.16 Subsequently,

the plaintiffs filed a notice of voluntary dismissal.17

In sum, in less than four months after the effective date of the 2023 final rule,

ATF had been enjoined from enforcing it against several groups of plaintiffs, and on

November 8, 2023, it was universally vacated. Because of the ongoing litigation and the

Government later appealed the injunction to the Fifth Circuit, but the parties stipulated to dismiss the

appeal, which the court granted. Jt. Stip., Mock v. Bondi, No. 24-10743 (5th Cir. July 17, 2025), Dkt. 80.

2023 final rule. In other words, no further classifications were issued as to industry

members or the public and no one was investigated based solely on possessing a braced

firearm.

Additionally, the goal of the 2023 final rule was to alleviate confusion by

clarifying ATF’s position and analysis on firearms with attached stabilizing braces and

help the public understand FATD’s underlying analysis in classifying firearms equipped

with stabilizing braces; however, the result was confusion as individual makers were

unsure how to apply highly technical criteria to their firearms. In light of the ambiguity

created by the regulations, it would have been challenging for individuals who make or

possess braced weapons to determine whether their firearms qualified as a “rifle” based

on the existence of a stabilizing brace or would fall within the purview of the NFA or

GCA. As an example, the factors in the final rule may have been overinclusive or

underinclusive and thus difficult to apply in particular cases. Given the difficulties in

applying the 2023 final rule, owners of weapons that would be considered “rifles” under

the final rule might not have been on notice before it was vacated and enjoined.

Moreover, two courts addressed the merits of the final rule, holding that parts of

the rule were arbitrary and capricious.18 The Eighth Circuit took issue with the rule

because it lacked a standard for measuring whether a brace provided enough “surface

area” to allow a weapon to be fired from the shoulder. In particular, it found that ATF

failed to “provide some range of flexibility in explaining the total surface area that allows

for shouldering a weapon.”19 The Eighth Circuit also took issue with two of the final

rule’s factors to determine whether a weapon is designed and intended to be fired from

the shoulder. Specifically, the court held that the final rule did not address how ATF

18 See Mock v. Garland, 2024 WL 2982056, at *5 (N.D. Tex. June 13, 2024); Firearms Regul.

Accountability Coal., Inc. v. Garland, 112 F.4th 507, 519 (8th Cir. 2024).

19 112 F. 4th at 521.would evaluate marketing materials and community use of the weapon, nor what was

relevantly “representative” of community use.20 In summary, the Eighth Circuit noted

that an “agency may promulgate a ‘holistic, multi-factor, weight-of-the-evidence test,’

but only if that test ‘define[s] and explain[s] the criteria the agency is applying.’”21 “The

Final Rule misses that mark.”22 The district court in Mock, supra, went a step further and

found all of the six factors “impermissibly vague,” and that the six-factor test “provides

no meaningful clarity about what constitutes an impermissible stabilizing brace.”23 Thus,

whatever clarity the agency hoped to provide, it was not successful in the view of

reviewing courts.

ATF is not issuing a new rule at this time. Each firearms submission to FATD is

unique in some way, and ATF has concluded that a pre-determined factored approach

that may or may not be relevant to the classification at issue is not the best method to

begin such classification of a firearm. Each submission will have unique characteristics

that make the firearm designed to be fired with one hand versus designed to be fired from

the shoulder.

II. Proposed Rule

Due to the confusion generated by the 2023 final rule, the courts’ conclusions that

it was arbitrary and capricious, concerns about sufficient notice, and the benefits of case-

by-case classifications based on the unique designs of each firearm, ATF proposes to

rescind the changes made by the 2023 final rule and rely on the statutory language

without further elaboration. Additionally, the proposed rule is necessary to conform

ATF’s regulatory provisions in parts 478 and 479 to the court decision vacating the rule.

Following the rule’s vacatur, ATF has been prevented from enforcing the rule

regulated parties that the 2023 regulation change is no longer in effect. ATF has

determined that it is a waste of resources to continue defending and trying to enforce the

2023 final rule.

Accordingly, this proposed rule would remove the revised portions of the

regulatory definitions of “rifle” that further defined the term “designed or redesigned,

made or remade, and intended to be fired from the shoulder.” The regulatory definitions

of “rifle” in 27 CFR 478.11 and 479.11 would be as they were prior to the 2023 final

rule. The pre-2023 definition of “rifle” tracked the GCA’s and NFA’s statutory

definitions and did not further define “designed or redesigned, made or remade, and

intended to be fired from the shoulder.”

Upon finalization of this rule, the resulting definition of “rifle” in § 478.11 would

read, “A weapon designed or redesigned, made or remade, and intended to be fired from

the shoulder, and designed or redesigned and made or remade to use the energy of the

explosive to fire only a single projectile through a rifled bore for each single pull of the

trigger.” Likewise, upon finalization of this rule, the resulting definition of “rifle” in §

479.11 would read, “A weapon designed or redesigned, made or remade, and intended to

be fired from the shoulder and designed or redesigned and made or remade to use the

energy of the explosive in a fixed cartridge to fire only a single projectile through a rifled

bore for each single pull of the trigger, and shall include any such weapon which may be

readily restored to fire a fixed cartridge.”

ATF seeks comments on all aspects of this proposed rule and its costs and benefits.

III. Statutory and Executive Order Review

A. Executive Orders 12866 and 13563

Executive Order 12866 (Regulatory Planning and Review) directs agencies to

assess the costs and benefits of available regulatory alternatives and, if regulation isnecessary, to select regulatory approaches that maximize net benefits.

Executive Order 13563 (Improving Regulation and Regulatory Review)

emphasizes the importance of agencies quantifying both costs and benefits, reducing

costs, harmonizing rules, and promoting public flexibility.

The Office of Management and Budget (“OMB”) has determined that this

proposed rule would be a “significant regulatory action” as defined in section 3(f)(1) of

Executive Order 12866 because it would have an impact on the economy of more than

$100 million in one year. The effect of this proposed rule would be to rescind the changes

made by the 2023 final rule and for the regulatory definitions of “rifle” in 27 CFR 478.11

and 479.11 to rely on the statutory language without further elaboration. This proposed

rule is necessary to conform ATF’s regulatory provisions in parts 478 and 479 to the

court decision vacating the rule. Revising the relevant definitions would provide clarity

and confirm for regulated parties that the 2023 regulation change is no longer in effect.

Pursuant to this change, individuals would be able to purchase firearms with an attached

“stabilizing brace” and forgo registration, fingerprinting, and photograph costs and

burdens, if the firearm is not intended to be fired from the shoulder and does not

otherwise fall within the statutory definition of “firearm” under the NFA. These savings

would result in an impact to the economy of more than $100 million.

ATF has laid out the impacts of this proposed rulemaking in OMB’s A-4

accounting statement here, in Table 1. Table 1 also illustrates the range of future

estimates in a low, primary, and high range as ATF’s Circular A-4 sensitivity analysis.

ATF then provides its normal regulatory cost-benefit analysis.

Effects

State, local, or

The rule will not impose an intergovernmental mandate, have significant or unique

effects on small governments, or have federalism or tribal implications.

Small businesses

For direct costs, this rule is deregulatory and would generate only savings, and only

for individuals, not businesses, including small businesses. However, there may be

indirect positive impacts. Small entities may experience an increase in revenue due to

weapons with brace configuration no longer undergoing NFA requirements such as

enhanced background checks.

Alternatives

No-change alternative: $0 cost and $0 benefits. This was rejected as more stringent without any

monetizable benefit. It would have provided potential qualitative safety benefits and potential increasing

certainty for purchasers and manufacturers about what constitutes a rifle.

Proposed alternative: $0 cost; $144.38 million benefit. This alternative was selected because the benefits

exceed the costs.

Publishing guidance documents alternative: this alternative was rejected because this alternative would not

have the force and effect of law and would leave a contradictory regulatory provision in existence.

1. Need statementOn January 13, 2023, the Attorney General signed the 2023 final rule, amending

ATF’s regulations to clarify when a rifle is designed, made, and intended to be fired from

the shoulder. The 2023 final rule was published in the Federal Register and took effect

on January 31, 2023. See 88 FR 6478. Within weeks of the 2023 final rule’s effective

date, several lawsuits were filed, all alleging violations of the APA, among a variety of

other grounds. ATF is now proposing to conform its regulations with the decisions in the

above-described litigation.

2. Population

Should this rule become final, individuals would be able to resume purchasing

firearms with an attached “stabilizing brace” as the public had done prior to the 2023

final rule, as long as the firearm is not intended to be fired from the shoulder and does not

fall within the statutory definition of “firearm” under the NFA. In the 2023 final rule that

defined these as NFA firearms and thus required persons to register them, ATF estimated

that a range of 3 million to 7 million firearms with attached stabilizing braces were

manufactured between the years 2012 and 2021.24 Since ATF does not know how many

of these firearms would now be manufactured and sold once they are no longer regulated

as NFA weapons, ATF is using 7 million firearms as the primary estimate because

manufacturers would likely ramp up manufacturing and sales of these firearms in the

public sphere. Furthermore, the 7 million figure would likely be most accurate within the

foregoing range, as ATF anticipates the popularity and awareness of these firearms would

be greater than when they were first manufactured and sold because they would no longer

be NFA firearms. Since the primary estimate is 7 million over the course of 10 years,

ATF estimates this would have an annual effect on 700,000 firearms.25

0002 [https://perma.cc/2J5Q-LZ4M].

25 875,000 annual firearms = 7,000,000 manufactured over 8 years / 8 years of production.3. Costs

The deregulatory cost savings for this rulemaking arise from persons who

purchase a firearm with attached stabilizing brace no longer incurring the time and cost

needed to apply to transfer and register such items as NFA firearms. Applying to transfer

and register an NFA firearm requires a person to complete and submit an ATF Form

5320.4, Application to Transfer and Register NFA Firearm (Tax-Paid) (“Form 4”), and

its supporting documents.

Currently, ATF estimates it takes an average of 3.78 hours to complete the Form 4

application, which includes time to obtain fingerprints and photographs to submit with

the Form 4.26 In addition, ATF estimates the average cost for a photograph at $17.27 ATF

assumes for the purposes of this analysis that it would also take approximately 10 miles

of driving to obtain photographs. For individuals to obtain fingerprints, ATF estimates an

average cost of $22, based on information it has gathered.28 ATF assumes for purposes of

this analysis that it would take approximately 10 miles of driving to obtain fingerprints.29

To estimate the deregulatory savings from driving, ATF used the General Services

Administration’s (“GSA”) per diem mileage rate, which was 70 cents per mile at the time

this proposed rule was drafted.30 If the rule is finalized as proposed, the public would no

longer incur these cost and time burdens, which would become savings.

Additionally, deregulatory savings include fees licensees charge for out-of-state

[https://perma.cc/U6UC-RZGH].transfers of NFA firearms. The 2023 final rule resulted in some out-of-state purchasers

also registering and transferring firearms with stabilizing braces as NFA firearms. Only

licensees may transfer firearms out-of-state, and licensees charge a fee for the out-of-state

transfer service, so persons who use such services incur those fees. NFA firearms may be

transferred only by a firearms licensee that pays the Special (Occupational) Tax (“SOT”)

to be licensed for NFA firearms. Persons purchasing firearms with stabilizing braces

from out-of-state must purchase from NFA licensees because the 2023 final rule

classified such firearms as NFA firearms. Under this proposed rule, many of these

firearms with attached stabilizing braces would no longer be NFA firearms and thus not

be subject to the NFA transfer fees. Instead, they would be subject to the out-of-state

transfer fees licensees charge for GCA transfers. GCA out-of-state transfer fees are

typically between $25 to $50 per transaction, a quarter of the cost of NFA transfer fees.

However, ATF is unable to calculate an aggregate savings due to a lack of statistical data,

including the number of individuals who purchased these firearms as NFA firearms and

how many purchased from outside of their states of residence.

ATF also notes that, at the time of the 2023 final rule, and continuing until

December 31, 2025, persons who registered an NFA firearm also had to pay a $200 tax

for each one. Although persons did incur this cost, ATF cannot include this cost in

projected savings arising from this proposed rule because, in July 2025, Congress passed

a law reducing the tax rate to $0 for certain NFA firearms effective January 1, 2026,

including firearms with stabilizing braces. As a result, this proposed rule would not result

in saved taxes by the time any final rule might be issued.

To calculate the savings from this proposed rule, ATF first had to determine the

value of time for those impacted by the rule. Individuals purchasing these firearms would

likely be purchasing them in their leisure time; therefore, ATF estimated a leisure wage

rate using methodology established by the Department of Health and Human Services(“HHS”), updated to account for the latest available data.31 The HHS methodology is to

first obtain the average U.S. median non-leisure weekly wage from the Bureau of Labor

Statistics (“BLS”), and divide it by 40 hours to derive the median hourly non-leisure

wage. Step two is to obtain the average U.S. real household income before taxes and after

taxes from the Census Bureau, and divide one by the other to determine the net household

income rate. Step three applies the net -income rate to the median non-leisure hourly rate

derived in step one, to calculate the hourly leisure wage. Table 2 shows the steps and data

ATF used under this methodology to determine an updated leisure wage.

Based on Table 3 above, ATF estimates that this rulemaking would generate cost

savings of $165 (rounded) per Form 1 application. At an estimated 875,000 firearms

manufactured in any given year, this would provide an annual and annualized savings of

$144.38 million per year. The 10-year undiscounted cost savings would be $1.4 billion.

4. Benefits

ATF does not anticipate any monetizable disbenefits (i.e., costs) arising from this

proposed rule. However, ATF notes that the rule could have a qualitative disbenefit to

public safety (i.e., adverse impacts). The Department of Justice issued the 2023 final rule

in part because some individuals and entities affix purported “stabilizing braces”

designed to facilitate shooting from the shoulder to firearms in order to circumvent NFA

requirements. Congress chose to regulate short-barreled rifles and other NFA items more

stringently, finding them to be especially dangerous to the community if not regulated,

since they are used for violence and criminal activity. See United States v. Gonzalez, No.

2:10-cr-00967, 2011 WL 5288727, at *5 (D. Utah Nov. 2, 2011) (“Congress specifically

found that ‘short-barreled rifles’ are primarily weapons of war and have no appropriate

sporting use or use for personal protection.” (quoting S. Rep. No. 90-1501, at 28 (1968))).Should a person choose to circumvent the NFA by effectively making unregistered

“short-barreled rifles” by attaching an accessory such as a “stabilizing brace,” these

dangerous, easily concealed weapons would pose an increased public safety problem.

Removing from the regulations the criteria for assessing whether a given stabilizing

brace/accessory-firearm configuration qualifies as an NFA firearm increases that public

risk. It also increases the uncertainty for purchasers and manufacturers as to whether a

given firearm configuration would fall under the NFA or not. However, ATF has no data

from which to quantify these potential disbenefits, which would depend on how many

manufacturers or individuals attempt to circumvent the requirements. At the same time,

such disbenefits would be offset to some degree by classifications that ATF provides to

industry that request advice on their products, thereby reducing confusion and potential

costs from producing and selling firearms that would turn out to fall under NFA

requirements. ATF provided this service before the 2023 final rule and continues to do so

with enhanced review procedures and controls to ensure consistency in classifications.

5. Alternatives

Alternative 1. Maintaining the status quo (no action alternative).

During the previous administration, ATF published the 2023 final rule on firearms

with attached stabilizing braces.32 In that rule, the effect of clarifying the meaning of

“designed and intended to be fired from the shoulder” resulted in a majority of large

pistols with certain attached stabilizing braces being classified as short-barreled rifles,

which resulted in them falling within the purview of the NFA. Based on the 2023 final

rule, persons purchasing firearms with an attached stabilizing brace would have had to

register the firearm as an NFA weapon and pay a $200 tax. Maintaining the status quo

would continue these costs, i.e., the costs associated with registering the firearm except

32 See Factoring Criteria for Firearms With Attached “Stabilizing Braces,” 88 FR 6478 (Jan. 31. 2023).for the $200 tax after January 1, 2026. Maintaining the status quo potentially has

qualitative public safety benefits and potential certainty about rifles. ATF rejected this

alternative due to the burden on the public to comply with the NFA requirements.

Alternative 2. Proposed alternative (rulemaking).

The alternative proposed in this rulemaking would effectively rescind the above

requirements for persons to apply for approval and register as NFA firearms large pistols

with attached stabilizing braces in order to purchase and lawfully own such firearms. By

removing these requirements, this alternative would provide deregulatory savings to

individuals wishing to purchase such firearms and facilitate the purchase without having

to go through the NFA application and approval process. This alternative is being

proposed due to the savings it would generate for the public.

Alternative 3. Publishing guidance.

Under this alternative, ATF would publish guidance instead of a rulemaking.

When ATF published the 2023 final rule, we provided guidance regarding specific types

of firearm configurations with an attached stabilizing brace that could be considered as

falling under the NFA to assist the public regarding the effect of the rule. Additional

guidance would not remove the amendments from the 2023 final rule or reduce confusion

generated from that rule, in which individuals were unsure how to apply highly technical

criteria to their firearms attached with firearms accessories, nor would it address certain

judicial decisions that found some of the factors to be arbitrary. Therefore, this alternative

was rejected.

B. Executive Order 14192

Executive Order 14192 (Unleashing Prosperity Through Deregulation) requires an

agency, unless prohibited by law, to identify at least ten existing regulations to be

repealed or revised when the agency publicly proposes for notice-and-comment or

otherwise promulgates a new regulation that qualifies as an Executive Order 14192regulatory action (defined in OMB Memorandum M-25-20 as a final significant

regulatory action under section 3(f) of Executive Order 12866 that imposes total costs

greater than zero). In furtherance of this requirement, section 3(c) of Executive Order

14192 requires that any new incremental costs associated with such new regulations

must, to the extent permitted by law, also be offset by eliminating existing costs

associated with at least ten prior regulations. However, this proposed rule would not be

an Executive Order 14192 regulatory action.

This rule as proposed would be a significant regulatory action as defined by

Executive Order 12866 because it would have an impact on the economy of over $100

million each year throughout its 10-year analysis period. However, because the economic

impact would consist of more than $100 million in annual deregulatory savings, it would

not impose costs greater than zero. This proposed rule would remove the previously

added regulatory and registration requirements and save the public from the costs and

burdens of complying with them. ATF therefore expects this rule, if finalized as

proposed, to qualify as an Executive Order 14192 deregulatory action (defined by OMB

Memorandum M-25-20 as a final action that imposes total costs less than zero).

C. Executive Order 14294

Executive Order 14294 (Fighting Overcriminalization in Federal Regulations)

requires agencies promulgating regulations with criminal regulatory offenses potentially

subject to criminal enforcement to explicitly describe the conduct subject to criminal

enforcement, the authorizing statutes, and the mens rea standard applicable to each

element of those offenses. This proposed rule would not create a criminal regulatory

offense and is thus exempt from Executive Order 14294 requirements.

D. Executive Order 13132

This proposed rule will not have substantial direct effects on the states, the

relationship between the federal government and the states, or the distribution of powerand responsibilities among the various levels of government. Therefore, in accordance

with section 6 of Executive Order 13132 (Federalism), the Director has determined that

this proposed rule would not impose substantial direct compliance costs on state and local

governments, preempt state law, or meaningfully implicate federalism. It thus does not

warrant preparing a federalism summary impact statement.

E. Executive Order 12988

This proposed rule meets the applicable standards set forth in sections 3(a) and

3(b)(2) of Executive Order 12988 (Civil Justice Reform).

F. Regulatory Flexibility Act

Under the Regulatory Flexibility Act, 5 U.S.C. 601–612, agencies are required to

conduct a regulatory flexibility analysis of any proposed rule subject to notice-and-

comment rulemaking requirements unless the agency head certifies, including a statement

of the factual basis, that the proposed rule would not have a significant economic impact

on a substantial number of small entities. Small entities include certain small businesses,

small not-for-profit organizations that are independently owned and operated and are not

dominant in their fields, and governmental jurisdictions with populations of less than

50,000.

The Director certifies, after consideration, that this proposed rule would not have

a significant economic impact on a substantial number of small entities as it removes

previously added requirements, thereby also removing any costs or burdens of complying

with them. This proposed rule affects individuals but does not affect small entities in a

way that would require a regulatory flexibility analysis. At most, the proposed rule, if

promulgated as proposed, could have an indirect positive impact for small entities that

manufacture stabilizing braces, in that more firearm owners might purchase these

braces—because this rule could likely remove the risk that the resulting firearms would

be subject to the registration requirements of the NFA. However, this would notconstitute a negative impact, additional cost or burden, or a barrier to entry for small

entities. In addition, ATF has no way to measure this speculative benefit. Therefore, ATF

is not including an Initial Regulatory Flexibility Analysis for this rule.

H. Unfunded Mandates Reform Act of 1995

This proposed rule does not include a federal mandate that might result in the

expenditure by state, local, and tribal governments, in the aggregate, or by the private

sector, of $100 million or more in any one year, and it would not significantly or uniquely

affect small governments. Therefore, ATF has determined that no actions are necessary

under the provisions of the Unfunded Mandates Reform Act of 1995.

I. Paperwork Reduction Act of 1995

Under the Paperwork Reduction Act of 1995 (“PRA”), 44 U.S.C. 3501–3521,

agencies are required to submit to OMB, for review and approval, any information

collection requirements a rule creates or any impacts it has on existing information

collections. An information collection includes any reporting, record-keeping,

monitoring, posting, labeling, or other similar actions an agency requires of the public.

See 5 CFR 1320.3(c). This proposed rule does not create any information collection

requirements, but it impacts one existing information collection covered under the PRA.

It would impact OMB control number 1140-0014: Application to Transfer and Register

NFA Firearm (Tax-Paid), which includes ATF Form 5320.4 (“Form 4”). As discussed

above, this proposed rule would reduce the number of persons who would have to

complete and submit Form 4 because persons would no longer have to register all

firearms with attached stabilizing braces as NFA firearms. The title and description of the

information collection involved in this rule, as currently approved by OMB, follows. A

description of those who provide the information and an estimate of the total annual

burden follow. The estimate covers the time for reviewing instructions, searching existing

sources of data, gathering and maintaining the data needed, and completing andreviewing the collection.

Title: Application to Transfer and Register NFA Firearm (Tax-Paid)

OMB control number: 1140-0014

Summary of the information collection: Persons with an NFA firearm must apply to ATF

for approval to transfer and register the firearm as required by the NFA (26 USC 5812).

ATF Form 5320.4 (“Form 4”) is the prescribed means for submitting this application,

facilitates and records the firearms transfer, and also serves as proof of registration once

approved.

Need for information and proposed use: ATF’s NFA Division uses the information on

this form to determine whether the applicant may legally make and register the firearm

under federal, state, tribal, and local law. The form also identifies the transferor,

transferee, and firearm(s). 26 U.S.C. 5812 provides that ATF cannot approve an

application if receiving or possessing the firearm would place the person receiving the

firearm in violation of law. The form asks an individual transferee to respond, under

penalties of perjury, to questions to determine whether they are prohibited by federal law

from possessing firearms.

Description of the respondents affected by this proposed rule: Individuals or households

Number of current respondents: 546,424 annually. This number would decrease pursuant

to this proposed rule.

Frequency of response: once

Response time estimate: 12 minutes per form (overall reduction from 30 minutes, due to

conversion to eForm, changes proposed in this rule, and other related changes)

Burden of response: 109,285 hours total for all respondents

IV. Public Participation

A. Comments sought

ATF requests comments on the proposed rule from all interested persons. ATFspecifically requests comments on the clarity of this proposed rule and how it may be

made easier to understand. In addition, ATF requests comments on the costs or benefits

of the proposed rule and on the appropriate methodology and data for calculating those

costs and benefits.

All comments must reference this document’s RIN 1140-AA98 and, if

handwritten, must be legible. If submitting by mail, you must also include your complete

first and last name and contact information. If submitting a comment through the federal

e-rulemaking portal, as described in section IV.C of this preamble, you should carefully

review and follow the website’s instructions on submitting comments. Whether you

submit comments online or by mail, ATF will post them online. If submitting online as

an individual, any information you provide in the online fields for city, state, zip code,

and phone will not be publicly viewable when ATF publishes the comment on

https://www.regulations.gov. However, if you include such personally identifying

information (“PII”) in the body of your online comment, it may be posted and viewable

online. Similarly, if you submit a written comment with PII in the body of the comment,

it may be posted and viewable online. Therefore, all commenters should review section

IV.B of this preamble, “Confidentiality,” regarding how to submit PII if you do not want

it published online. ATF may not consider, or respond to, comments that do not meet

these requirements or comments containing excessive profanity. ATF will retain

comments containing excessive profanity as part of this rulemaking’s administrative

record but will not publish such documents on https://www.regulations.gov. ATF will

treat all comments as originals and will not acknowledge receipt of comments. In

addition, if ATF cannot read your comment due to handwriting or technical difficulties

and cannot contact you for clarification, ATF may not be able to consider your comment.

ATF will carefully consider all comments, as appropriate, received on or before

the closing date.B. Confidentiality

ATF will make all comments meeting the requirements of this section, whether

submitted electronically or on paper, and except as provided below, available for public

viewing on the internet through the federal e-rulemaking portal, and subject to the

Freedom of Information Act (5 U.S.C. 552). Commenters who submit by mail and who

do not want their name or other PII posted on the internet should submit their comments

with a separate cover sheet containing their PII. The separate cover sheet should be

marked with “CUI//PRVCY” at the top to identify it as protected PII under the Privacy

Act. Both the cover sheet and comment must reference this RIN 1140-AA98. For

comments submitted by mail, information contained on the cover sheet will not appear

when posted on the internet, but any PII that appears within the body of a comment will

not be redacted by ATF and may appear on the internet. Similarly, commenters who

submit through the federal e-rulemaking portal and who do not want any of their PII

posted on the internet should omit such PII from the body of their comment and in any

uploaded attachments. However, PII entered into the online fields designated for name,

email, and other contact information will not be posted or viewable online.

A commenter may submit to ATF information identified as proprietary or

confidential business information by mail. To request that ATF handle this information as

controlled unclassified information (“CUI”), the commenter must place any portion of a

comment that is proprietary or confidential business information under law or regulation

on pages separate from the balance of the comment, with each page prominently marked

“CUI//PROPIN” at the top of the page.

ATF will not make proprietary or confidential business information submitted in

compliance with these instructions available when disclosing the comments that it

receives but will disclose that the commenter provided proprietary or confidential

business information that ATF is holding in a separate file to which the public does nothave access. If ATF receives a request to examine or copy this information, it will treat it

as any other request under the Freedom of Information Act (5 U.S.C. 552). In addition,

ATF will disclose such proprietary or confidential business information to the extent

required by other legal process.

C. Submitting comments

Submit comments using either of the two methods described below (but do not

submit the same comment multiple times or by more than one method). Hand-delivered

comments will not be accepted.

• Federal e-rulemaking portal: ATF recommends that you submit your comments

to ATF via the federal e-rulemaking portal at https://www.regulations.gov and follow the

instructions. Comments will be posted within a few days of being submitted. However, if

large volumes of comments are being processed simultaneously, your comment may not

be viewable for up to several weeks. Please keep the comment tracking number that is

provided after you have successfully uploaded your comment.

• Mail: Send written comments to the address listed in the ADDRESSES section of

this document. Written comments must appear in minimum 12-point font size, include

the commenter’s first and last name and full mailing address, and may be of any length.

See also section IV.B of this preamble, “Confidentiality.”

D. Request for hearing

Any interested person who desires an opportunity to comment orally at a public

hearing should submit his or her request, in writing, to the Director within the 90-day

comment period. The Director, however, reserves the right to determine, in light of all

circumstances, whether a public hearing is necessary.

Disclosure

Copies of this proposed rule and the comments received in response to it are
