The Dead Air KeyMicro Flash Hider (brand part number DA120) is a short, lightweight .30-caliber flash hider machined from 4140 heat-treated alloy steel, threaded 5/8-24 and finished in Black Nitride. Dead Air built the KeyMicro line around the same mounting technology found in its industry-best KeyMo system, so it suits a wide variety of rifle platforms beyond just Dead Air-suppressed builds. KeyMicro muzzle devices are also compatible with the KeyMo Adapter, giving owners a straightforward path to a quick-attach Dead Air suppressor down the road. It is a compact, no-nonsense flash hider for shooters who want KeyMo-grade mounting technology in a shorter footprint.
