Abstract

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."

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

[[Page 24454]]

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 federal law.
---------------------------------------------------------------------------

    \1\ Some NFA and GCA provisions still refer to the ``Secretary 
of the Treasury.'' However, the Homeland Security Act of 2002, 
Public Law 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.
---------------------------------------------------------------------------

    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 
readily restored 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

[[Page 24455]]

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.
---------------------------------------------------------------------------

    \3\ See 86 FR 30826.
---------------------------------------------------------------------------

    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\ 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.
---------------------------------------------------------------------------

    \4\ See Factoring Criteria for Firearms With Attached 
``Stabilizing Braces,'' 88 FR 6478 (Jan. 31, 2023).
---------------------------------------------------------------------------

    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\

    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 to 
the plaintiffs in that case. Then, on November 8, 2023, a separate 
district court in the 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

that plaintiffs challenging the 2023 final rule were likely to succeed 
on the merits and remanded the case to the district court with

    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 various 
injunctions, for all intents and purposes, ATF has never actively 
enforced the 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 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 nationwide, so 
revising the relevant definitions will provide clarity and confirm for 
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 Sec.  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 Sec.  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 is necessary, 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.

[[Page 24457]]

    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.

1. Need Statement
    On 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\

---------------------------------------------------------------------------

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 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

[[Page 24459]]

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.

 wage.
------------------------------------------------------------------------

    Based on the methodology outlined by HHS, the estimated leisure 
wage is $26, which is used to calculate the hourly savings. Based on 
these cost inputs, Table 3 below outlines the Form 4 application costs 
and hourly burdens forgone and estimates the overall savings per Form 4 
application.

Per-application savings.............................  ..............  ..............  ..............  ................  ................          165.00
--------------------------------------------------------------------------------------------------------------------------------------------------------

    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

[[Page 24460]]

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 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.
---------------------------------------------------------------------------

    \32\ See Factoring Criteria for Firearms With Attached 
``Stabilizing Braces,'' 88 FR 6478 (Jan. 31. 2023).
---------------------------------------------------------------------------

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 14192 regulatory 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 power and 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,

[[Page 24461]]

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 not constitute 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, recordkeeping, 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 and reviewing 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 U.S.C. 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. ATF specifically 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 <a href="https://www.regulations.gov">https://www.regulations.gov</a>. 
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 <a href="https://www.regulations.gov">https://www.regulations.gov</a>. 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

[[Page 24462]]

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 not 
have 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.
    <bullet> Federal e-rulemaking portal: ATF recommends that you 
submit your comments to ATF via the federal e-rulemaking portal at 
<a href="https://www.regulations.gov">https://www.regulations.gov</a> 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.
    <bullet> 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 available through the federal e-rulemaking portal, at <a href="https://www.regulations.gov">https://www.regulations.gov</a> (search for RIN 1140-AA98).
