Adams Arms is a leading force in piston system AR-15 components and rifles. The 5.56 Mid-Length Tactical EVO Piston Upper Assembly with 14.5" barrel is a short-barreled upper that incorporates patented Adams Arms technology and the Samson Evolution free-floating forearm.

The mid-length piston system will give you the benefits of a longer forearm by providing 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 free-floating forearm is a 12.37" tube that extends around the gas block, giving you enough space to mount the removable picatinny rail pieces to meet all of your needs.

The AR-15 piston system parts and the barrel have been treated with a salt nitride melonite process making them harder and more corrosive resistant than hard chrome.
