Comstock Armory 4-Prong Flash Hider 1/2x28 .223/5.56 2.14" Black Nitride - Plan B Compatible

The Comstock Armory 4-Prong Flash Hider is a precision muzzle device threaded in standard 1/2x28 for .223 Remington / 5.56 NATO AR-platform barrels, engineered to deliver serious flash suppression while doubling as a Plan-B compatible suppressor mount for fast, repeatable suppressor attachment.

CNC-machined from 17-4 PH stainless steel and treated with a tough black nitride (melonite) finish, the four-prong design cuts muzzle flash without the timing shims required by many competing brakes. At just 2.14" overall length and 2.3 oz, it adds minimal bulk and weight to the host rifle, while the aggressive prong profile keeps blast signature down on short-barrel and night-vision setups.

The hider ships predrilled for pin-and-weld, allowing builders running 14.5" barrels to permanently attach the device and reach the 16" minimum overall length required for a non-NFA configuration. 3/4" wrench flats on the body make installation and removal straightforward at the bench, and the unit threads onto any standard 1/2x28 muzzle without the need for shims or indexed timing.

The rear of the hider accepts common .900"-24 adapter interfaces, making it directly compatible with the Q Plan-B, Rearden Atlas, and Comstock LPA suppressor mounting systems. Whether you're pinning a 14.5" SBR carbine or building a duty rifle that needs quick suppressor swap capability, the Comstock Armory 4-Prong delivers durable stainless construction, low flash signature, and versatile suppressor interface compatibility in one compact package.
