Advanced Armament 64743 Blackout Flash Hider 9mm 1.75 in- 2.375 in L Aerospace Alloy Black Nitride

AAC's Blackout Flash Hider has proprietary features to 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 nitride finish provide the highest level of durability. It is military tested and selected. This is the non-mount version for use without a silencer, in Fast-Attach for 9MM HK MP5-style 3-Lug barrels.
