Radian Weapons A-DAC 15 Lower Receiver — Black

The Radian Weapons A-DAC 15 is a billet-machined AR-15 lower receiver constructed to provide fully ambidextrous controls and a user-focused bolt hold-open solution. Machined from 7075-T6 aluminum, the receiver integrates an A-DAC (Ambidextrous Dual Action Catch) that allows right-handed shooters to lock the bolt to the rear without changing their firing grip. The design includes a SART spring-loaded plunger to reduce upper/lower wobble and ships with proprietary hardware and enhanced takedown pins for a semi-complete installation.
