The Noveske KX3 Flash Hider is designed to increase reliability in short barreled AR-15 pistols by increasing back pressure. Also, the KX3 directs the muzzle blast forward of the shooter which alleviates most of the discomfort when firing the AR-15 with an abbreviated barrel. The KX3 is made of chrome moly steel that is heat-treated for further durability. The entire assembly is then phosphated for corrosion resistance and individually serialized for quality control. Although originally designed for short barreled AR-15's the Noveske KX3 will work on any barrel length
