The Andro Corp 5.56 NATO AR-15 Barreled Upper Receiver is built from high quality parts like a 4150CMV barrel, 7075-T6 aluminum receiver and heavy duty Melonite finishes. The upper receiver also features a dry lube finish on the interior reducing the friction with the bolt carrier for a smoother and more reliable action. The flat top picatinny rail is T-marked for easy identification of your optics position if you plan on using a quick detach mount.
