Banned
No. PICA names arm braces as an assault-weapon feature, so a braced detachable-magazine semiautomatic pistol is prohibited. Effective 2023-01-10.
Controlling law: 720 ILCS 5/24-1.9; 720 ILCS 5/24-1(a)(7)(ii) & 5/24-2(c)(7)
Contested entry
PICA applies a one-feature test to a pistol that accepts a detachable magazine, and one listed feature is a buffer tube, arm brace, or other part that protrudes horizontally behind the pistol grip and is designed to allow the firearm to be fired from the shoulder. PICA is written independently of federal classification, so the vacatur of the ATF rule changed nothing here, and an AR pistol independently trips the magazine-outside-the-grip feature, meaning removing the brace does not cure it. Registration closed January 1, 2024 and no new acquisitions are permitted. Illinois short-barreled rifles are Curio & Relic only under 5/24-2(c)(7), so the Form 1 path is closed for ordinary builds. The Seventh Circuit upheld PICA in Barnett v. Raoul on July 9, 2026.
Federal law
The 2023 ATF stabilizing-brace rule was vacated nationwide and is not enforced, but that does not categorically make every brace-equipped firearm a pistol. Under 26 U.S.C. § 5845, federal classification still turns on whether the specific weapon is designed and intended to be fired from the shoulder. A brace-equipped firearm that meets the short-barreled-rifle definition requires NFA approval and registration; a configuration that remains a pistol does not. Building an actual short-barreled rifle is still an NFA act: Form 1, fingerprints, CLEO notification, a NICS check, and registration all apply. The federal making tax has been $0 since January 1, 2026 under the One Big Beautiful Bill Act, and eForm approvals currently run days to a couple of weeks.
Scope: Pistol stabilizing braces (SB Tactical, Maxim Defense, A3 Industries and similar) and the braced pistols they mount on. Short-barreled rifles and state assault-weapon feature tests are tracked as separate classes.
