Product Description Machined from billet 7075-T6 aluminum, the Radian Weapons A-DAC 15 lower receiver is built to deliver durable performance with truly ambidextrous control for AR-15 style firearms. Along with a Talon 45/90 ambidextrous safety selector, left-side magazine release, and right-side bolt release, it features Radian&';s patented A-DAC (Ambidextrous Dual Action Catch) system that lets right-handed shooters lock the bolt to the rear without removing their firing hand from the fire control.

Proprietary hardware is included, such as an extended bolt catch and enhanced takedown pins.
