Comstock Armory Compact Flash Hider 1/2x28 9mm Facemount Black Nitride - Plan B Compatible

The Comstock Armory Compact Flash Hider is a short, suppressor-ready muzzle device machined from high-strength 17-4 PH stainless steel and finished in a corrosion-resistant black nitride coating. Designed around a 1/2x28 thread pattern and intended for use on 9mm barrels (suitable for bullets up to and including 9mm), this facemount version is purpose-built for the Plan-B suppressor mounting system and is also compatible with common .900"-24 suppressor adapters for fast, repeatable suppressor attachment and removal.

The Compact Flash Hider directs expanding gases outward and forward to reduce blast baffle wear on a mounted suppressor, while its short 1.6 inch overall length and lightweight 1.85 oz design make it an excellent fit on compact 9mm AR pistols, 9mm PCCs, and short-barrel rifle builds where length and weight savings matter. Compared to a standard A2-style flash hider, the design is reported to cut perceived recoil by up to 50 percent, while still keeping the muzzle signature in check on un-suppressed hosts.

Installation is straightforward: the 1/2x28 thread pattern fits all common 9mm barrels, and the shoulderless barrel fit with no-shim install design makes it a clean drop-on option. The Plan-B interface lets the end user install or remove a compatible suppressor without tools and without changing point of impact, making the FHC-12-9-FM a flexible host-side mounting solution for shooters running both suppressed and unsuppressed configurations.
