CMMG Barrel AR-15 300 AAC Blackout (7.62x35mm) Medium Taper Contour 1 in 7" Twist 16.1" Carbine Gas Port Chrome Moly Matte
The barrel is composed of Chrome Moly Steel and finished inside and out with CMMG's durable salt bath nitride finish. The unique treatment applied to the barrel surface-hardens the metal, extending barrel service life by reducing friction in the bore and lessening bore surface wear. It 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 of the benefits of traditional chrome lining without suffering the accuracy degradation commonly encountered due to uneven application of chrome inside the barrel's bore.
