Comstock Armory Compact Muzzle Brake .578×28 – .45 Cal BorePlan-B Compatible Suppressor Mount
Built for durability and suppressor performance, this Compact Muzzle Brake (MBC) is compatible with common .900″-24 adapters such as the Comstock LPA, Q Plan-B, and Rearden Atlas. Designed to reduce recoil and extend suppressor life, the MBC also functions as a sacrificial blast baffle, significantly minimizing blast baffle wear during high-volume shooting.
Unlike traditional directional brakes, this model features a rotationally symmetric design, eliminating the need for shims or timing—making installation simple and efficient.
Precision machined from 17-4 PH stainless steel and finished in a tough black nitride coating, it offers exceptional strength, corrosion resistance, and long-term reliability. The .578×28 thread pattern makes it compatible with many common rifle-caliber barrels.
