  • DOJ Legal Filing Renews Concerns About ATF’s Posture on Braced Pistols
    on March 20, 2026 at 9:07 PM

    The saga of ATF’s enforcement of the National Firearm Act’s “short barreled rifle” provisions against braced pistols has been a roller coaster ride of shifting interpretations. NRA-ILA has been keeping up with, reporting on, and advocating for reform the entire time. It seemed we had reached a low point with the publication of the rule Factoring Criteria for Firearms With Attached “Stabilizing Braces” during the Biden-Harris administration. Yet NRA, along with other pro-Second Amendment groups, successfully challenged that rule in court, and its enforcement was enjoined against NRA members, as well as other plaintiff groups in similar suits. Eventually, the rule was vacated in its entirety. Unfortunately, that did not provide the lasting relief many had hoped.
