Comstock Armory Hybrid Muzzle Device 1/2x28 Full Size 9mm Bore - Plan-B Suppressor Mount

Comstock Armory Hybrid Muzzle Device 1/2x28 - 9mm Bore - Plan-B Suppressor Mount

Engineered for shooters who demand performance without compromise, the Hybrid Muzzle Device by Comstock Armory delivers the perfect balance of recoil reduction, flash suppression, and suppressor compatibility. Designed to work seamlessly with popular .900″-24 adapters like the Comstock LPA, Q Plan-B, and Rearden Atlas, this full-size muzzle device enhances your rifle’s control and durability while maintaining a sleek, no-nonsense profile.

Crafted from high-strength 17-4 PH stainless steel and finished in black nitride, the Hybrid Device is built to withstand extreme conditions and high-volume fire. Its rotationally symmetric design eliminates the need for timing or shims, while pre-drilled pin holes make it easy to permanently attach to 14.5" barrels. Whether you're running suppressed or unsuppressed, this device acts as a sacrificial blast baffle, protecting your suppressor and improving overall shooting dynamics—without the obnoxious blast signature of traditional brakes.
