Dead Air Armament KeyMo Flash Hider 1/2x28 – AR-15 5.56/.223 Suppressor Mount

The Dead Air KeyMo Flash Hider combines primary flash suppression with quick-attach suppressor mounting capability. Designed as a standalone flash hider that doubles as a KeyMo suppressor host, this muzzle device reduces visible signature while providing a secure, repeatable interface for KeyMo-compatible suppressors. When running unsuppressed, it functions as a conventional flash hider; when you need sound suppression, it accepts any KeyMo mount suppressor with a simple quarter-turn lockup.

Machined from high-strength steel with a durable black oxide finish, the KeyMo Flash Hider installs on standard 1/2x28 threaded barrels common to AR-15 rifles in 5.56 NATO and .223 Remington. The KeyMo taper mount system ensures consistent suppressor alignment and zero retention across multiple attach/detach cycles. Includes crush washer for proper timing. Note: Suppressor use requires compliance with NFA regulations including Form 4 approval and appropriate tax stamp.
