Dead Air DA304 KeyMount Flash Hider .30 cal | M15x1

The Dead Air DA304 KeyMount Flash Hider is a .30 caliber muzzle device engineered to provide a stable, low-profile mounting point for KeyMo-equipped suppressors. Its design centers on mass-shifted equal-length tines to eliminate the characteristic ping of traditional flash hiders, and it is built for compatibility with KeyMo and KeyMicro adapters. Constructed from 4140 HT alloy steel and finished in Black Nitride, the unit includes a pre-drilled pin-and-weld hole to support permanent installations when desired.
