The Comstock Armory Compact Muzzle Brake (brand part no. MBC-12-9) is a 9mm brake with 1/2×28 threads, sized for PCCs and 9mm AR builds that want recoil control without a long can of steel on the muzzle. Comstock Armory keeps it to 1.6 inches overall and 1.9 ounces, and the design installs without shim timing — it torques straight on using the 3/4-inch wrench flats. Among rifle accessories, this compact brake favors 9mm carbine shooters chasing flatter follow-up shots.
