Comstock Armory Compact 9mm Flash Hider - 1/2x28 - FHC-12-9

The Comstock Armory Compact 9mm Flash Hider is a short, suppressor-ready muzzle device designed for firearms with 1/2×28 threads and projectiles up to 9mm. Its compact 1.6-inch profile helps reduce muzzle flash while keeping added length and weight to a minimum.

The FHC uses the common .900″-24 Plan-B interface, making it compatible with systems such as the Comstock LPA, Q Plan-B, and Rearden Atlas. Its internal geometry redirects expanding gases outward to help reduce suppressor blast-baffle wear, while the rotationally symmetric design eliminates the need for timing with shims.
