The 5.56 Carbine MOE 16" Upper is a standard M4 style upper that incorporates the patented Adams Arms technology. The piston system parts and the barrel have been treated with our salt nitride Meloniting process making them harder and more corrosive resistant than hard chrome. Add the patented Adams Arms piston system and you'll have an upper that will run cleaner, cooler, and longer than any other AR upper you own.
Includes bolt carrier assembly and charging handle
