AAC Blackout Flash Hider - 5.56mm 51T
The AAC Blackout is an extremely effective flash hider that is also a silencer mounting device. The Blackout has a 3 prong design with very thick prongs with rounded edges so they don't catch on everything. The 3 prong symmetrical design does not need to be timed with shims, simplifying installation. Threaded with AAC's 51 Tooth Ratchet Mount for AAC Sound Suppressors. It is built to be as tough and durable as possible with AAC's SCARmorô finish over heat-treated 17−4PH stainless. Rear of device is recessed to slightly overlap the barrel 0.06" with barrels up to .750 diameter. Will not mount properly on barrels with diameter larger than .750".
Diameter at prongs: 0.860"
Diameter where it overlaps barrel: 0.935"
Weight: 4.3 ounces
