Comstock Armory Compact Muzzle Brake 1/2x36 - 9mm Bore Plan-B Compatible Suppressor Mount

Comstock Armory Compact Muzzle Brake 1/2x36 - 9mm Bore
Plan-B Compatible Suppressor Mount

Designed for durability and performance, this Compact Muzzle Brake (MBC) is compatible with common .900″-24 adapters such as the Comstock LPA, Q Plan-B, and Rearden Atlas. Built to reduce recoil while protecting your suppressor, the MBC also functions as a sacrificial blast baffle, significantly reducing wear on your suppressor’s internal components.

Unlike many traditional brakes, this model features a rotationally symmetric design, eliminating the need for timing or shims—making installation simple and straightforward.

Machined from 17-4 PH stainless steel and finished in black nitride, it offers outstanding strength, corrosion resistance, and long-term durability. The 1/2-36 thread pattern makes it ideal for select AR9 and pistol-caliber carbine barrels.
