Statute-cited, not legal advice, last verified 2026-10-20
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 is an NFA firearm; a configuration that remains a pistol is not. Since October 9, 2026, ATF does not enforce the NFA's Form 1 approval and registration requirements for SBRs, as a matter of enforcement discretion, but an SBR still needs an approved Form 5320.20 before interstate transport, state law still applies, and ATF says enforcement could resume if the policy changes. The federal making tax has been $0 since January 1, 2026 under the One Big Beautiful Bill Act.
Federal baseline verified 2026-10-09. 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.
