Product Description

The LANTAC USR™ Upper Standard Receiver is a precision-machined billet upper receiver engineered to provide exceptional fit, smooth operation, and enhanced reliability. Manufactured from 7075-T6 aluminum, it features a proprietary ultra-smooth internal bore that reduces bolt carrier friction for improved cycling performance.

Critical machining operations ensure the barrel nut threads, receiver bore, and barrel extension surfaces are perfectly concentric and perpendicular, promoting precise barrel alignment and consistent accuracy. Finished with a Mil-Spec Type III Class 2 hardcoat anodizing, the USR™ is built for long-lasting durability in demanding shooting environments.
