The DPMS AR15 B5 lower receiver is a .223 Remington and 5.56 NATO lower built on 7075-T6 aluminum forgings. It has MIL-A-8625F Type III Class 2 hardcoat anodizing and a manual safety. The kit includes a milspec carbine receiver extension with a standard carbine buffer, a B5 Bravo stock and grip, and a B5 enhanced trigger guard. A Panther Polished Trigger, or PPT, and a staked M4 lock nut are included as well.

This lower suits a builder who wants a ready-to-build lower for a standard AR-15 upper. The milspec extension and carbine buffer match a standard carbine setup, and the B5 stock and grip are already included, so the builder can focus on the upper and the rest of the rifle. Hunters who plan to use the finished rifle should check their state wildlife agency's rules for AR-15 rifles and cartridges before they build.
