All KKM barrels are made using U.S. manufactured 416 Stainless steel bar stock which is then heat treated and vacuum tempered to 42 to 45 RC. All Barrels are CNC machined to obtain superior dimensional tolerances. Using our unique Button Rifling process, all KKM barrels offer superior accuracy over stock barrels.
