Comstock Armory Recessed Micro Brake (1/2-28, 5.56 bore) Plan-B Suppressor Mount

Recessed Micro Brake compatible with common .900-24 adapters like the Comstock LPA, Q Plan-B, and Rearden Atlas. The recessed micro brake greatly reduces recoil and blast baffle wear, and unlike most brakes out there, it does not need to be timed with shims. It also has minimal protrusion into the suppressor to ensure proper fitment, even when used with recessed style adapters.
