Regardless of a federal court docket vacating the Biden-era pistol brace rule, the ATF says it by no means stopped implementing its underlying authorized interpretation — and it’s not planning to.
A bombshell court docket submitting submitted March 16 in a Southern District of Texas case has gun house owners and Second Modification advocates sounding the alarm: the Bureau of Alcohol, Tobacco, Firearms and Explosives has quietly admitted in federal court docket that it continues to implement its interpretation that some pistol-brace-equipped firearms are unregistered short-barreled rifles (SBRs) — a federal felony carrying as much as 10 years in jail — despite the fact that the rule that codified that interpretation has been universally vacated.
The Case
The submitting got here in State of Texas et al. v. Bureau of Alcohol, Tobacco, Firearms and Explosives, Civil Motion No. 6:23-cv-00013, in response to a movement filed by Gun House owners of America (GOA) looking for an injunction to cease ATF from implementing the authorized theories that underpinned the now-dead brace rule. ATF filed its reply transient on March 16, 2026, arguing the case is moot — as a result of the rule is gone — however concurrently acknowledging that it’s nonetheless implementing the NFA’s and GCA’s regulation of short-barreled rifles in opposition to some brace-equipped pistols.
Within the ATF’s personal phrases from the submitting:
“Plaintiffs additionally make a lot of the truth that defendants proceed to implement the NFA’s and GCA’s regulation of short-barreled rifles in opposition to some brace-equipped pistols, despite the fact that the Rule has been universally vacated. However that ought to come as no shock…”
The company went additional, arguing that its continued enforcement is fully unbiased of the rule itself:
“At any fee, that defendants proceed to implement sure statutory necessities and prohibitions that they’ve been delegated the authority and accountability to manage is irrelevant as to whether plaintiffs’ APA problem to the now-defunct Rule is moot.”
Translation: the rule could also be useless, however the ATF says it nonetheless has the statutory authority — and the intent — to prosecute People with braced pistols as felons.
Fast Backstory
Pistol stabilizing braces had been developed in 2012 and initially authorised by the ATF, which stated attaching one to a pistol didn’t reclassify the firearm as a short-barreled rifle. In 2014, the company doubled down, confirming that even shouldering a braced pistol didn’t change its classification. That reassurance helped drive adoption to an estimated 7 to 10 million or extra People.
Issues acquired difficult in 2015 when ATF reversed course, briefly suggesting shouldering a brace might make a gun proprietor a felon, earlier than reversing that reversal in 2017. Then, in January 2023, the Biden administration dropped the hammer with a sweeping administrative rule that successfully categorised the overwhelming majority of braced pistols as unregistered SBRs. House owners got the choice to register their firearms free of charge — however compliance estimates ranged from solely 6% to eight%.
Lawsuits flew instantly. In 2025, a federal court docket universally vacated the rule, and the Trump administration collectively dismissed not less than one associated case — Mock v. Bond — with the Firearms Coverage Coalition. It appeared just like the struggle was over.
It wasn’t.
The Authorized Catch
GOA’s lawsuit, filed in Texas, had particularly challenged the rulemaking course of below the Administrative Process Act (APA). The ATF is now utilizing that slim framing in opposition to gun house owners, arguing that as a result of GOA’s lawsuit focused the rule — not the underlying statutory interpretation — and the rule is now useless, the case is moot. The court docket, ATF argues, can not enjoin the company from implementing authorized theories that exist unbiased of any particular rule.
In brief: you killed the rule, not our interpretation. And we’re nonetheless performing on it.
What This Means for Gun House owners
If the ATF’s place holds, thousands and thousands of People who bought braced pistols in good religion — counting on a number of written ATF assurances going again over a decade — might nonetheless face federal prosecution. The company is basically claiming that its prior written approvals don’t bind it, the rule being vacated doesn’t bind it, and that absent a court docket order particularly focusing on its statutory interpretation, it should proceed treating sure braced pistols as felony SBRs.
GOA and different Second Modification organizations are anticipated to push again. However for now, gun house owners holding braced pistols could be clever to seek the advice of an lawyer and keep intently tuned to additional developments on this case.
