Dead Air KeyMo Flash Hider | .30 Cal | 5/8-24 | DA302

The Dead Air KeyMo Flash Hider (DA302) is a muzzle device and suppressor mount designed for .30-caliber systems using 5/8-24 threads. It uses a patent-pending, mass-shifted equal-length tine design intended to eliminate the characteristic “ping” found on some muzzle devices when used with Dead Air KeyMo/KeyMicro-equipped suppressors. The KeyMo Flash Hider is constructed of heat-treated steel with a black nitride finish and includes a pre-drilled pin and weld hole at the 6 o’clock position.

Typical applications include providing a dedicated mounting interface for NFA-rated suppressors during precision shooting setups and for range training where reliable attach/detach performance and reduced muzzle signature are desired.
