UR-01-E3-M4) comes with the standard features of a Mil-Spec upper receiver, forged from 7075-T6 aluminum and finished in a tough, black hardcoat anodize. Chambered for .223 Remington/5.56 NATO, it’s built to work with any Mil-Spec AR-15 lower receiver, making it a solid foundation for a build, a repair, or a spare upper.
