The Radian Weapons A-DAC 15 Lower Receiver in Radian Gray is a billet-machined AR-15 pattern lower built from 7075-T6 aluminum (Radian Weapons part no. R0388). It features integral trigger guard geometry, a flared magazine well and fully ambidextrous controls. The patented A-DAC catch lets you lock the bolt back without changing grip, and the SART system helps reduce upper-to-lower wobble. A Type III hard anodize base with a Radian Gray Cerakote topcoat protects the surface from wear. It is a clean, rigid starting point for a custom AR-15 build.
