Legal
Yes. Braces are unregulated, but a braced firearm 26 inches or shorter is a pistol under Michigan law with pistol purchase rules.
Controlling law: MCL 750.222(f); MCL 750.224b; MCL 28.422
Contested entry
Michigan classifies by overall length rather than by what the rear attachment is called: any firearm 26 inches or less in length is a pistol, so a braced AR pistol carries the full pistol regime, meaning a purchase license or concealed pistol license for private transfers, an RI-060 pistol sales record filed with the state police, and pistol carry rules. Because the test is length, a long or fully extended brace that pushes the firearm past 26 inches flips it out of pistol status, and MCL 750.228 bars newly registering anything over 26 inches as a pistol. Michigan has no assault weapon ban, and short-barreled rifles are lawful under MCL 750.224b when federally compliant.
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.

What to buy
If your state is green on the map, these are the braces that matter. The SB Tactical SBA3, SBA5, and SBA6 are the buffer-tube cuff standards across AR pistols, the Maxim Defense SCW is the shortest collapsed PDW system shipping, and the FS1913A and A3 Industries HDA3 Universal cover folding 1913 hosts like the Scorpion, Stribog, and Kuna.
