Description
The Comstock Armory Full Size Flash Hider is a suppressor-ready muzzle device built for AR-platform rifles and pistols chambered in 9mm Luger. Its 5/8×24 thread pitch is also commonly found on 350 Legend and .30-caliber barrels, making it a versatile option for pistol-caliber carbine and barrel-shortening builds.
Machined from high-strength 17-4 PH stainless steel and finished in a tough Black Nitride (Nitride/Melonite) coating, the FHL-58-9 measures 2.14 inches overall and weighs 2.3 oz. The body is pin-drilled for permanent installation on 14.5″ barrels via pin and weld, allowing builders to maintain a non-NFA overall length while keeping the muzzle suppressor-ready.
The Plan-B compatible mounting interface allows quick attachment and removal of compatible Plan-B mount suppressors. Gas vent geometry directs expanding gases outward to reduce blast baffle wear on the host suppressor, extending service life and reducing blast at the shooter’s position.
