Dark Hour Defense Billet Upper Receiver AR15 Black

Dark Hour Defense Billet Upper Receiver AR15 Black. The upper is machined from 7075 T6 billet aluminum and has a type 3 mil-spec hard coat anodizing. The upper has extended feed ramps and a 1913 top rail. The design features a "dove tail" which is an elongated triangular section at the rear of the receiver; this increases rigidity. The triangular section at the rear of the receiver enhances reliability and function as the triangular section extends back towards the shooter. The design of the upper has a "widened slot" to accommodate the installation of a rail section (such as a hand guard or a bipod) without sacrificing the iconic look of an AR.
