US Rifle Upper Receiver (RTZ)

Description

Our billet crafted upper receiver cut to accept our proprietary RTZ (Return To Zero) optic mounting system. This grants users true 3-axis return to zero technology, the only of its kind.

US Rifle AR15 Uppers are made from 7075 aluminum just like the lowers.  Why?  Because this particular alloy is stronger and lighter than 6061 alloy aluminum.  When you build a rifle with a US Rifle receiver set, you’re building functional art.  The lines blend seamlessly.  The minimalistic brass deflector, the omission of a forward assist, and the Thermal fit of the barrel all contribute to the intentional efficiency and efficacy.

We offer Uppers as a raw (no finish), Mil-Spec Class 2 (Black), Type III (Hardcoat) Anodize.

Thank you for choosing ADR!
