AAC BLACKOUT FH 51T 7.62MM Flash Hider – 5/8x24 Thread Mount

The AAC BLACKOUT FH 51T is a flash hider designed for 7.62mm rifles, built to reduce muzzle flash while serving as a mounting platform for AAC 51-tooth fast-attach suppressors. Machined from heat-treated steel, this flash hider directs combustion gases to minimize visible signature without adding excessive weight or length to your barrel.

Threaded 5/8x24, this flash hider is compatible with common .308 Winchester and 7.62x51mm barrels. The 51T ratchet interface allows quick, repeatable suppressor attachment when paired with AAC 51T-compatible silencers. Includes crush washer for proper timing and installation.
