Comstock Armory MBL 1/2x28 Muzzle Brake Suppressor Mount - Plan-B Compatible

Take control of your rifle’s performance with the MBL Muzzle Brake—a game-changing upgrade for shooters who demand maximum recoil reduction, suppressor protection, and effortless installation. Designed for compatibility with top-tier .900″-24 adapters like Comstock LPA, Q Plan-B, and Rearden Atlas, the MBL delivers quick suppressor attachment without compromising durability or alignment.

Unlike traditional brakes that require tedious shimming, the MBL features a rotationally symmetric design that installs cleanly and securely—no timing needed. Its sacrificial baffle architecture dramatically reduces blast baffle wear, extending the life of your suppressor while keeping your rifle running smoother and flatter. Built from high-strength 17-4 PH stainless steel and finished in black nitride, this brake is engineered to withstand the harshest conditions and highest round counts.
