The AAC Blackout flash suppressor is the most efficient design available. The proprietary features eliminate muzzle flash, even on CQB-Length barrels. The Blackout is inherently stronger and more impact resistant than four prong designs, while not being subject to the rapid erosion of closed ended units. A high strength corrosion-resistant aerospace alloy, and ultra hard Nitride finish provide the highest level of durability. Military tested and selected.
