The Dead Air KeyMicro Flash Hider in 5/8-24 SIG Taper (Dead Air part no. DA120) is a short, lightweight muzzle device that works as a flash hider by itself. Dead Air designed it for use with either the KeyMicro Adapter or the KeyMo Adapter, and paired with one of them it becomes a suppressor mounting platform. It is machined from 4140 HT alloy steel with a Black Nitride finish and measures 2.063 inches overall. The design uses the same technology found in Dead Air’s KeyMo system. For a host with a 5/8-24 SIG Taper muzzle thread, it is a compact way to get a flash hider that can later carry a suppressor.
