The AR-15 flash can is a muzzle device that directs flash and gases forward, away from the shooter. It reduces side blast and keeps the shooter comfortable during rapid fire. Builders thread it onto standard AR-15 barrels with a 1/2″ x 28 thread pitch. It fits AR pistols, SBRs, and standard rifle uppers without modification. Shooters use it on short-barreled builds for close quarters and indoor range sessions. An AR-15 flash can improves shooting comfort without significantly reducing the flash signature of the muzzle.
