The Dead Air KeyMicro Flash Hider 1/2-28 is a 9mm muzzle device threaded 1/2-28 from Dead Air Silencers (brand part no. DA115). A pistol-caliber carbine is a natural home, either bare or ahead of a KeyMicro suppressor mount. It is machined from 4140 heat-treated alloy steel with a Black Nitride finish and measures 2.063 inches overall, a short, lightweight shape suited to a variety of platforms. Designed for the KeyMicro Adapter or KeyMo Adapter, it also functions as a minimalist flash hider by itself.
