Lantac USR AR-15 Stripped Upper Receiver

The Lantac® USR™ AR-15 Stripped Upper Receiver boasts a special proprietary bore that is ultra smooth to help reduce bolt carrier friction for much smoother operation. What’s more, the barrel nut threads, bore, and barrel extension surfaces are all machined in one operation so they’re perfectly concentric and perpendicular to the barrel and fixing assembly. Designed with M4 feed ramps, this striped upper receiver is constructed from billet 7075-T6 aluminum with a corrosion-resistant hardcoat anodized finish. Made in USA.

This is a stripped upper receiver. Forward assist and port door NOT included.
