The SilencerCo ASR Flash Hider (brand part no. AC1278) is a black nitride muzzle device cut with 9/16-24 left-hand threads for .30 caliber and 7.62 NATO hosts, built to significantly suppress muzzle flash and protect a shooter’s vision in low-light environments. It doubles as the mounting point for SilencerCo’s ASR quick-attach suppressors, so it stays on the rifle when the can comes off. A patent-pending resonance suppression method eliminates the tuning-fork ring common to competing three-prong flash hiders, keeping shots quieter and more controlled at the muzzle. Because its left-hand threads are cut shorter than many muzzle devices, shooters running a barrel around 13.7 to 13.9 inches sometimes pin and weld this flash hider permanently to bring the total barrel length up to the legal 16-inch rifle minimum.
