The AR-15 flash hider mounts to the muzzle and reduces the visible flash signature when the rifle fires. It disperses burning gases as they exit the barrel, which cuts down on visible flash at the muzzle. Shooters use this muzzle device on AR-15 rifles for better visibility during low-light shooting. It threads onto standard 1/2″ x 28 threaded barrels for a secure fit. It works on carbine and rifle-length builds without modification. This device keeps the shooter better oriented on target during rapid fire sessions.
