The Radian A-DAC 15 lower receiver is machined from billet 7075-T6 aluminum and built for AR-15-style platforms. It features ambidextrous controls, an integral trigger guard, and a flared magazine well, with Radian’s A-DAC mechanism designed to let right-handed shooters lock the bolt to the rear without changing hand position. The SART receiver tensioning system helps reduce upper-to-lower wobble for a consistent fit.
