Unique design redirects concussion forward to provide better flash suppression than standard A2 suppressor on short-barreled AR-15/M16/M4 rifles and other centerfire gas-operated weapons. Virtually eliminates side blast to protect nearby personnel during CQB, building entries, and when shooting from inside vehicles. Lessens felt recoil and reduces muzzle rise to help keep sights on the target for fast follow up shots and superior recoil management on full-auto assault rifles, especially with barrels 13" or shorter. High-carbon steel with matte black manganese phosphate finish stands up to the heat and pressure of thousands of rounds. Convenient, ¾" wrench flats allow easy installation with the same wrench used to remove factory flash suppressor. Crush washer included.
