AAC BLACKOUT FH 90TV Flash Hider 1/2x28 – AR-15 5.56/.223/300 BLK

The AAC BLACKOUT FH 90TV is a three-prong flash hider designed to reduce muzzle flash while serving as a quick-detach mounting platform for AAC 90-tooth suppressor systems. The 90-tooth taper mount design provides a secure, repeatable lockup with minimal point-of-impact shift when attaching or removing compatible suppressors. As a standalone device, it effectively disrupts flash signature without adding excessive length or weight to your rifle.

Installation requires a 1/2x28 threaded barrel, standard on most AR-15 rifles chambered in 5.56 NATO, .223 Remington, and 300 Blackout. Constructed from heat-treated steel with a black oxide finish for corrosion resistance. Includes crush washer for proper timing. Compatible with AAC suppressors featuring the 90-tooth mount system—verify suppressor compatibility before purchase as this mount is not universal across all AAC models.
