The Dead Air KeyMicro Flash Hider 5/8-24 (Dead Air part no. DA116) is a short, lightweight muzzle device with a 9mm bore, cut to the 5/8-24 thread. It is machined from 4140 heat-treated alloy steel with a black nitride finish and runs 2.063 inches long. It suits a host that uses the 5/8-24 pitch and wants flash control without adding length. Dead Air designed it for the KeyMicro Adapter or the KeyMo Adapter, and it also functions as a minimalist flash hider by itself.
