Dead Air DA303 KeyMo Flash Hider 30 Cal M14x1 LH

The Dead Air DA303 KeyMo Flash Hider is a high-strength muzzle device purpose-built for .30 caliber rifle hosts, combining aggressive flash suppression with a precision suppressor mounting interface. Machined from 4140 heat-treated alloy steel, this flash hider is engineered to withstand hard use across a wide range of platforms while serving as the key component of Dead Air's renowned KeyMo mounting system.

The KeyMo flash hider uses mass-shifted equal-length tines that significantly reduce visible muzzle flash while eliminating the metallic "ping" common to many competing designs. At 2.70" long and weighing approximately 4 oz, the DA303 keeps your muzzle compact and balanced. Threading is M14x1 left-hand (LH), making it a direct-fit choice for .30 caliber hosts with matching left-hand threads.

Beyond flash suppression, the DA303 functions as the mounting hub for any suppressor equipped with a Dead Air KeyMo adapter, including the Sandman Series, Nomad-30, and the KeyMicro-equipped Wolfman. The integrated KeyMo interface allows rapid attachment of your suppressor with rock-solid lockup.

Whether you are building a dedicated suppressed host or simply want a premium flash hider that doubles as a future-ready suppressor mount, the Dead Air DA303 KeyMo Flash Hider delivers the rugged construction and proven engineering that has made the KeyMo system an industry favorite.
