Comstock Armory MBC 5/8x24 Compact Facemount 9mm Bore Muzzle Brake - Plan-B Compatible

Comstock Armory MBC 5/8x24 Compact Facemount 9mm Bore Muzzle Brake - Plan-B Compatible

When space is tight and performance matters, the Comstock MBC (Muzzle Brake Compact) delivers. Designed for shooters who demand recoil control, suppressor compatibility, and rugged reliability in a compact footprint, the MBC is the ideal upgrade for modern carbines and unconventional platforms like the PSA AKV, Tavor/X95, VZ 61, and SCAR 16s—especially those lacking a proper barrel shoulder.

Crafted from high-strength 17-4 PH stainless steel and finished in durable black nitride, this rotationally symmetric brake eliminates the need for timing or shims. It’s built to reduce recoil, minimize blast baffle wear, and serve as a sacrificial baffle to extend suppressor life. Compatible with popular .900″-24 adapters like the Comstock LPA, Q Plan-B, and Rearden Atlas, the MBC offers fast suppressor attachment and removal without compromising performance.
