The AAC BLACKOUT flash suppressor is the most efficient design available to today's enthusiast or operator. The proprietary features eliminate muzzle flash, even on CQB length barrels. The BLACKOUT is inherently stronger and more impact resistant than any of the four prong designs, while at the same time 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.
