AAC 51T BLACKOUT FLASH HIDER

The 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 SCARmor finish provide the highest level of durability. Military tested and selected.
