AAC Blackout Flash Hider - 7.62mm 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. Great for .300 Blackout and 6.8SPC guns that have 5/8x24 thread patterned barrels as well as 7.62x51mm guns. Rear of device is recessed to slightly overlap the barrel 0.30" with barrels up to .750 diameter. Will not mount on barrels with diameter larger than .750".
Diameter at prongs: 0.860"
Diameter where it overlaps barrel: 0.935"
Weight: 3.8 ounces
