Introduction
Some folks want more restrictions on firearms. Some gun owners aren’t bothered by restrictions on types of firearms they don’t own. Both groups might want to pay attention to what the ATF is doing to bump stocks… err... I mean stabilizing braces.
Background on the ATF’s Final Rule
A few weeks ago, the Bureau of Alcohol, Tobacco, Firearms, and Explosives (BATFE or ATF) announced their final rule on stabilizing braces (2021R-08F “Factoring Criteria for Firearms with Attached ‘Stabilizing Braces’”) and submitted it for publishing to the Federal Register. Since then many readers have asked for my opinion or interpretation of the rule. Rather than jumping the gun and immediately sharing my thoughts, I decided to take a moment to process the information while setting up a conversation with some folks that know way more about this than I do. In other words, I called my friends at Right To Bear for some help.
2025 Update
In a Jan. 13 email, ATF clarified that recent claims labeling all braced pistols as short-barreled rifles (SBRs) were “overbroad,” walking back earlier guidance from an FIPB official; while the agency reaffirmed its stance is more limited, legal clarity around pistol braces under the NFA remains unsettled and subject to ongoing litigation.

Disclaimer
Since Right To Bear operates amidst the legal space, it made sense to me that they might know quite a bit more about this regulatory change than I do. The conversation we had was educational and frightening. Before I get into the nuts and bolts, I also need to be very clear that what is written in this post is absolutely not legal advice. I am not an attorney and neither was Scott, the Right To Bear representative that I spoke with. What I will share with you is strictly my opinion and understanding which may very well be incorrect and subject to change as the situation evolves and more information becomes available.
Rule Publication and Scope
The new rule—which was officially published in the Federal Register on January 31, 2023—has effectively reclassified certain firearms with attached stabilizing braces as short-barreled rifles (SBRs). This begs several questions:
Which firearms?
What are stabilizing braces?
What are SBRs?
Unfortunately, the answers to some of these questions are ambiguous and appear to be the beginning of a rapidly expanding legal quagmire. Nevertheless, that’s what we are here to explore.
What Is an SBR?
A short-barreled rifle is a rifle with:
A rifled barrel length of less than 16”, or
An overall length of less than 26”
…that is designed to be fired from the shoulder. An SBR is regulated under the National Firearms Act (NFA), meaning you cannot legally own one without special authorization from the ATF. That process requires:
Submitting fingerprints and passport-style photos
Undergoing a background check
Paying a $200 tax stamp
Filing the proper paperwork
Possession without compliance is a felony, punishable by up to 10 years in prison and a $250,000 fine.
What Are Stabilizing Braces?
Stabilizing braces are devices attached to the rear of a firearm and designed to be secured against the forearm, aiding in stabilization. For years the ATF has approved their use on certain “pistols,” but under the new rule any pistol with an attached brace may now fall under the SBR definition.
Which Firearms Are Impacted?
Obvious Targets : AR- and AK-platform pistols with barrels under 16”
Potentially Impacted : Any pistol whose weight, size, or design resembles a traditional SBR
Moving Targets : If marketing materials, instructions, or social-media posts suggest shouldering the brace, that can trigger SBR status—even future posts.
Broader Implications
This rule sets a scary precedent: an administrative agency, without legislative authority, effectively creating or altering criminal laws. It could empower other agencies to restrict items—like natural-gas appliances or internal-combustion engines—via regulation, sidestepping Congress.
Risks for Pre-Existing Owners
Industry experts estimate 10–40 million owners have braces on pistols. Many may be unaware they’re suddenly in illegal possession of an SBR. Ignorance is no defense. A routine traffic stop or self-defense incident could expose an unregistered SBR, triggering felony charges.

ATF’s Five Compliance Options
Depending on local laws, not all options suit everyone. Consult an attorney before proceeding.
Option 1: Replace the Barrel
How : Swap for a ≥ 16” barrel (and ensure overall length ≥ 26”).
Pitfall : Storing removed parts nearby may be deemed “constructive possession.” Consider separate storage or disposal.
Option 2: Permanently Remove the Brace
How : Modify the brace or firearm so a brace can never reattach.
Pitfall : Keeping removed parts can still pose “constructive possession” risks.
Option 3: Forfeit to ATF
How : Turn the firearm in at an ATF office.
Pitfall : No fair-market compensation; you lose your property.
Option 4: Destroy the Firearm
How : Follow ATF guidelines for destruction.
Pitfall : Improper destruction may leave it “unserviceable” (still regulated as a firearm).
Option 5: Register as an SBR
How : File e-Form 1 by May 31, 2023 (fingerprints, photos, etc.).
Pitfall : Approval isn’t guaranteed; denials leave you illegally in possession. After the window, new acquisitions can’t use this route.
Curveballs and Caveats
Litigation Injunctions : A court could halt the rule mid-stream.
ATF FAQs Change : Removal or edits to official FAQs can create confusion.
Trust Ownership : Registering under a trust requires proof the trust owned it before Jan 31, 2023.
