AAC 100206 Blackout 51T Flash Hider 5.56mm 1/2-28TPI Black Nitride Alloy
AAC’s Blackout 51T flash suppressor is the most efficient design available. It has been military tested and selected. 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.
