AAC BLACKOUT 90T Flash Hider 1/2x28 – 51T Ratchet Mount Compatible

The AAC BLACKOUT 90T Flash Hider serves as both a stand-alone flash suppressor and a quick-detach mount for AAC 51T ratchet-mount suppressors. Its 90-tooth taper interface ensures repeatable, secure lockup when mounting compatible suppressors, while the prong design effectively breaks up muzzle flash during unsuppressed fire.

This muzzle device threads directly onto barrels with 1/2x28 TPI threading, standard for .223/5.56 NATO and .300 Blackout firearms. CNC-machined from heat-treated steel with a matte black finish for corrosion resistance. Includes crush washer for proper timing. Compatible with AAC 51T ratchet-mount suppressors only—not compatible with other AAC mounting systems or non-AAC suppressors without adapters.
