The Brownells Early 3 Prong 22 Caliber Flash Hider is a historically accurate muzzle device built to spec for retro and vintage AR-15 builds. Chambered in .22 caliber with 1/2"-28 threads, this steel flash hider replicates the iconic "duckbill" design that appeared on early Colt Model 601 rifles during the Vietnam War era. If you're piecing together a correct-period retro rifle or simply want the authentic look and function of first-generation AR hardware, this is the real deal—not a modern reinterpretation.
The three-prong design was eventually replaced on service rifles due to the lightweight prongs bending under field use, but for a display-quality build or shooter who isn't pushing the envelope, it delivers period-correct aesthetics. Brownells modeled this directly from original examples, so proportions and fit are genuine. The black phosphate finish matches the character of vintage military rifles and won't look out of place on a clone build.
Installation requires a strap wrench or 3-prong armorers wrench—this muzzle device has no wrench flats, so grab the right tool before you start. Whether you're restoring a parts kit or building a .22 LR upper from scratch, this flash hider keeps your vision authentic from muzzle to stock.
