Description

CMMG 12.5" Barrel SBN Multi Role (300 BLACKOUT)CMMG's Weapon Armament Surface Protection (WASP) 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.Length - 12.5"Material - 4140 CrMoProfile - Multi Role ProfileFinish - Salt Bath Nitride Finish (Melonite)Gas System Length - PistolGas Block Journal - .750"Twist Rate - 1:7 inchesMuzzle - 5/8"-24 TPIChamber - 300 BLKAll NFA/ATF Rules ApplyDepending on your state and local laws, you could use this barrel with a lower receiver that is a Registered SBR, or Pistol.
