Radian Weapons is best known for the Raptor ambidextrous charging handle and the Talon safety selector, and the Model 1 lower receiver brings that same obsessive machining to the foundation of an AR build. Radian's approach is to build fully ambidextrous controls into the receiver rather than bolting them on afterward.

This is the ADAC-15 lower in black — ADAC standing for Ambidextrous, Dual Automatic Catch, referring to the mirrored bolt catch and magazine release that let a left-handed shooter, or anyone shooting from an unconventional position, run the rifle without breaking their firing grip. A serialized receiver and a premium starting point for a serious AR-15 build.
