CMMG 16" 5.56mm SBN Barrel

CMMG's WASP finish (weapon armament surface protection) is a Salt Bath Nitride Finish surface conversion process or more commonly referred to as Nitriding. The Nitriding conversion is applied to the barrel inside and out, along with the front sight base on our LE rifles and uppers. Nitriding offers improved wear, abrasion, and corrosion resistance when compared to hard chrome lining or phosphating. Unlike chrome lining, where the chrome is built up on the surface, Nitriding converts the surface without the risk of dimensional build up. CMMG has been utilizing this nitriding process for many years with our LE series rifles.
