Are Pistol Braces Legal in Minnesota?

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.
