Advanced Armament Corp, AAC Blackout Flash Hider & Ratchet Suppressor Mount, 90-Tooth, 7.62mm, 5/8" x 24 RH Thread (SR-7), 5.56mm, 1/2" x 28 RH Thread (SR-5) - Matte

The BLACKOUT flash suppressor is the most efficient design available. The proprietary features 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 SCARmor finish provide the highest level of durability. Military tested and selected.

THESE FLASH HIDERS ARE FOR THE SR-7 & SR-5 ONLY AND CANNOT BE USED WITH ANY OTHER 90T SILENCERS.
