Sleek Billet Upper Receiver for AR-15

This billet upper receiver keeps up with Fortis’ commitment to high quality and top-notch aesthetics.  Cleanly machined lines make this one-piece receiver stand out from mil-spec, with smooth contours around the forward assist socket, and a slim brass deflector.

Mil-Spec Materials and Fit

Just like a standard AR-15 upper receiver, the Fortis Billet upper is machined from 7075-T6 aluminum.  Plus, it gets a mil-spec Type III Hardcoat Anodized finish, providing longterm durability against the elements.  Any standard AR-15 components like barrels, dust covers, forward assists, and charging handles work with this upper, so you can customize to your liking.

This receiver also features an additional charging handle latch on the right side, specifically for the Fortis Clutch Left-Handed Charging Handle.
