State Legality MatrixPistol BracesCalifornia
Statute-cited, last verified 2026-08-04
Restricted
Restricted. California does not ban braces categorically, but common detachable-magazine AR- and AK-pattern pistols are assault weapons and a shoulder-fired configuration may be a prohibited short-barreled rifle. Effective 2000-01-01.
Controlling law: Cal. Penal Code § 30515(a)(4)(D); Cal. Penal Code §§ 17170 & 33215
Contested entry
The brace is not itself a listed assault-weapon feature. Section 30515(a)(4)(D) reaches a semiautomatic pistol without a fixed magazine when it can accept a detachable magazine outside the pistol grip, which covers common AR- and AK-pattern pistols even without a brace. A semiautomatic pistol with a fixed magazine of ten rounds or fewer does not fall within § 30515(a)(4) or (5) on that basis alone. Separately, §§ 17170 and 33215 prohibit short-barreled rifles without a civilian NFA exemption, so a brace-equipped configuration that is designed and intended for shoulder firing can still create state and federal SBR exposure.
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.
