Are Pistol Braces Legal in Michigan?

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.
