Comstock Armory Compact 9mm Muzzle Brake – 5/8×24
The Comstock Armory Compact 9mm Muzzle Brake (SKU: FHC-58-9) is a streamlined, suppressor-ready muzzle device designed for 9mm platforms using larger barrel threads. It offers significant recoil reduction in a “micro” footprint while serving as a precision mounting interface.
The FHC-58-9 is engineered for 9mm carbines, sub-guns, and specialized rifles (like the .350 Legend) that utilize a 5/8×24 thread pitch. It is optimized for shooters who want to minimize the overall length of their firearm while retaining the ability to quickly attach a suppressor.Â
- Plan-B Compatible: Specifically designed to interface with the .900″-24 internal geometry used by the Comstock LPA, Q Plan-B, and Rearden Atlas mounts.
- Recoil Mitigation: The internal porting is tuned to vent high-pressure gases effectively, reducing felt recoil and muzzle flip for faster follow-up shots.
- Sacrificial Baffle: Functions as an initial blast baffle when a suppressor is attached, absorbing the erosive force of unburnt powder and hot gases to protect the silencer’s internal components.
- Zero-Timing Installation: The rotationally symmetric porting eliminates the need for shims or crush washers. It is designed to be torqued directly to the barrel shoulder for perfect concentricity
