AAC Blackout 51 Tooth Flash Hider Ratchet Mount 7.62/

Proprietary features eliminate muzzle flash even on CQB-length barrels. Blackout is inherently stronger and more impact-resistant than 4 prong designs while not being subject to the rapid erosion of closed-ended units. High strength corrosion-resistant aerospace alloy and ultra-hard Nitride finish provide the highest level of durability. Military tested and selected.
