The Dead Air KeyMicro Flash Hider 1/2-28 (Dead Air part no. DA115) is a short, lightweight muzzle device with a 9mm bore, cut to the common 1/2-28 thread. It is machined from 4140 heat-treated alloy steel with a black nitride finish and is 2.063 inches long overall. A pistol caliber carbine is a natural home for it, either bare or ahead of a KeyMicro mount. Dead Air designed it for the KeyMicro Adapter or the KeyMo Adapter, and it also works as a minimalist flash hider by itself.
