We carry CMMG accessories, including conversion kits, AR barrels, complete uppers and other parts kits designed to work with a variety of barrels from 9mm to 5.56 and .22. Most models feature CMMG’s Weapon Armament Surface Protection (WASP), which consists of a salt bath nitride finish to improve resistance against abrasions, corrosion and general wear and tear when compared to hard chrome- or phosphate-lined parts. This process, otherwise known as nitriding, helps prevent buildup and keeps operation smooth and seamless.

Our entire selection of CMMG AR15 parts is on sale, so shop with us today and save on your next addition to your AR build.
