CMMG AR-15 Revolution M4 LE A3 Flat-Top Upper Assembly 5.56x45mm NATO 1 in 9" Twist 16" Barrel Chrome Molly Matte with Revolution Modular Rail Handguard, Flash Hider
CMMG's durable Weapons Armament Surface Protection (WASP) Melonite treatment is a unique protective coating applied to the barrel that surface-hardens the metal, extending barrel service life by reducing friction in the bore and lessening bore surface wear. Also referred to as Nitriding, this treatment produces an extremely hard, slick surface on steel that resists carbon adhesion and increases corrosion resistance, making for easier cleaning and maintenance. Nitriding converts the steel's surface without any build-up, retaining all the benefits of traditional chrome lining without suffering from the accuracy degradation commonly encountered due to uneven application of chrome inside the barrel's bore.
