Comstock Armory Compact Muzzle Brake 1/2x28 9mm Black Nitride - Plan B Compatible

The Comstock Armory Compact Muzzle Brake is a compact, suppressor-ready muzzle device engineered for 9mm Luger and similar pistol-caliber carbines. Machined from 17-4 PH stainless steel and finished in a tough Black Nitride coating, it delivers long-lasting durability and corrosion resistance in a short, snag-free package.

This brake uses a standard 1/2x28 thread pattern, the industry-standard pitch for 9mm Luger rifle and pistol-caliber carbine barrels, and is rated for projectiles up to .357 diameter. The Plan-B mounting interface accepts common .900"-24 adapters from Q, Rearden, and the Comstock LPA system, letting you swap suppressors on and off quickly without tools. The rotationally symmetric design effectively tames felt recoil and shields the blast baffle of a mounted suppressor from carbon and debris.

Built for real-world use, the compact profile measures just 1.6" OAL and incorporates 3/4" wrench flats for easy installation and removal with a standard crows-foot or socket. Whether you run a 9mm AR-pattern carbine or any other pistol-caliber carbine with the appropriate thread pitch, this brake offers a clean balance of recoil control, suppressor compatibility, and a low-profile footprint.
