The 5.45 Carbine Tactical Evo 14.5" Upper is a short barreled upper that incorporates the patented Adams Arms technology and the Samson extended free floating forearm. The midlength piston system will give you the benefits of a longer forearm by giving the user a longer, more ergonomic grip, a longer sight radius between the front and the rear sight for quicker sight acquisition and less felt recoil. 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. The free floating Evolution rail was manufactured for us by Samson Manufacturing and is a 10" 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 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.

This 5.45 upper includes a 30 round stainless steel magazine and a Wolff Extra Power Hammer Spring.
