The Blackout 51T flash suppressor eliminates muzzle flash, even on CQB-length barrels. It 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. This model has 5/8x24 tpi threads.
