Dead Air's flash hider has a unique design featuring mass shifted equal length tines. The end result is a flash hider that does not "ping." It is compatible with our Sandman Series and other KeyMo equipped suppressors. The KeyMo flash hider is also compatible with our KeyMicro equipped Wolfman. When it comes to removal, the suppressor can be easily removed without carbon-locking onto the mount. This Flash Hider does come with a pre-drilled pin & weld hole at the 6 O'clock position.
