The Radian Weapons A-DAC 15 lower receiver (part no. R0391) is machined from billet 7075-T6 aluminum in an OD Green finish, built as a fully ambidextrous lower for AR15-style firearms. Beyond the Talon ambidextrous safety selector, left-side magazine release, and right-side bolt release, the A-DAC 15 features the patented A-DAC (Ambidextrous Dual Action Catch), which lets right-handed shooters lock the bolt to the rear without taking their hand off fire control. It is built for shooters who want serious ambidextrous functionality beyond the standard mirrored controls found on most AR-15 lowers.
