The Noveske KX3 Flash Hider is designed to increase reliability in short barreled AR-10 and LR-308 pistols and SBR's 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 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
