Comstock Armory Hybrid 9mm Flash Hider/Muzzle Brake – 5/8×24
The Comstock Armory Hybrid 9mm flash hider/muzzle brake (SKU: hyb-58-9) is a high-performance, multi-functional muzzle device designed for 9mm platforms using larger barrel threads. It provides a balanced solution for shooters who want the recoil reduction of a brake and the signature reduction of a flash hider in a single, suppressor-ready mount. The HYB-58-9 is engineered for 9mm carbines, sub-guns, and specialized hunting rifles (like .350 Legend) that utilize a 5/8×24 thread pitch. It functions as a highly effective standalone device or as a precision mount for Plan-B-style suppressor adapters.Â
- Hybrid port geometry: Internal porting bleeds off gases to reduce felt recoil and muzzle rise while disrupting gas flow to significantly reduce visible muzzle flash.
- Plan-B compatible: Fits perfectly within the .900″-24 internal geometry of the Comstock LPA, Q Plan-B, and Rearden Atlas suppressor mounts.
- Sacrificial baffle design: When suppressed, the hybrid ports take the brunt of the high-pressure gas and unburnt powder, protecting your suppressor’s blast baffle from premature erosion.
- Direct-to-shoulder install: The rotationally symmetric porting means no timing or shims are required—simply torque it directly to the barrel shoulder.
