This Tactical Upper Carbine is a M4 profiled upper that incorporates the patented Adams Arms Piston technology and a tactical extended free floating forearm. The piston system parts and the barrel have been treated with a salt nitride meloniting process, making them harder and more corrosive resistant than hard chrome. The free floating quad rail is manufactured by Samson Manufacturing and is a 10-inch rail that extends along the sides and bottom of the gas block, giving you more rail space for whatever your tactical needs may be. With the Adams Arms piston system, you'll have an upper that will run cleaner, cooler, and longer than any other AR upper you own.
