The Adams Arms Mid-Length Base Complete AR-15 Upper Assembly has everything you need in a piston upper assembly. This upper receiver can be connected to any standard AR-15 lower receiver.

Piston systems increase overall reliability while also decreasing the amount of maintenance required to keep the AR-15 operational. The short stroke gas piston operating system is designed to run cooler and cleaner than a standard direct impingement system. 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 mid-length piston system will also 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. This Adams Arms AR-15 upper incorporates M4-style handguards.
