All KKM barrels are made using U.S. manufactured 416R Stainless steel bar stock which is then heat treated and vacuum tempered to 42RC. All Barrels are CNC machined to obtain superior dimensional tolerances.

All Threaded Barrels also include a thread protector.

Using their unique Button Rifling process, all KKM barrels offer superior accuracy over stock barrels. Our Glock barrels come with fully supported match chambers for shooting factory or reloaded ammunition as well as lead or jacketed bullets.

Please note: Barrels may only be returned if they are unused and in re-sellable condition. If the item is defective—i.e., does not function—we will accept a return within the 30-day period only.
