Comstock Armory Compact 9mm Muzzle Brake – 1/2×36
The Comstock Armory Compact 9mm muzzle brake (SKU: MBC-1236-9) is a specialized, suppressor-ready muzzle device designed specifically for 9mm PCC (pistol caliber carbine) platforms that utilize the traditional 1/2×36 thread pitch.
The MBC-1236-9 is the compact version of Comstock’s flagship muzzle brake. It is engineered for shooters who need to reduce felt recoil and muzzle rise while maintaining a short overall firearm length.Â
- Precision 9mm porting: the internal chamber and ports are specifically tuned for 9mm gas volume, effectively mitigating the “snap” of blowback-operated PCC systems.
- Plan-B compatible: designed to interface seamlessly with the .900″-24 adapter system, including the Comstock LPA, Q Plan-B, and Rearden Atlas.
- Sacrificial baffle protection: when a suppressor is attached, the brake acts as a primary blast baffle, absorbing the erosive force of high-pressure gases to extend the life of your silencer.
- No timing required: the rotationally symmetric design allows a simple “direct-to-shoulder” installation without shims or crush washers.
- Durable build: machined from 17-4 PH stainless steel with a black nitride finish for maximum heat and corrosion resistance.
