The Battle Arms Development Authority Elite Lightweight Billet Upper Receiver in black anodized (brand part no. AE-UR-BLK) is a stripped AR-15 upper machined from 7075-T6 billet aluminum. Battle Arms gives it a patent-pending lightweight design and cuts an M4 feed ramp into the receiver. The finish is a hard anodized flat black, and the receiver accepts standard Mil-Spec AR upper parts. It suits a light AR-15 build that still runs common parts.

Key Specifications

• The receiver is precision CNC machined from billet 7075-T6 aerospace aluminum, a strong alloy that keeps weight down.
• The design is patent-pending and lightweight, built to trim ounces from the upper.
• Weight is about 6.3 ounces, a figure worth counting when you build a light rifle.
• An M4 feed ramp is cut into the receiver to help rounds feed from the magazine into the chamber.
• The finish is hard anodized flat black to MIL-A-8625F, Type III, Class 2, which stands up to wear.
• It is compatible with standard Mil-Spec AR upper receiver parts, so parts you already own will fit.
• It is compatible with the FORTIS REV II rail (the version with indexing tabs), a handguard option for the build.
• The platform is AR-15, so it pairs with an AR-15 lower and common AR-15 parts.
• The upper ships stripped, so you add the barrel, bolt carrier group and handguard yourself.
• All components, material and packaging are made in the USA, a plus for builders who prefer domestic parts.
