Radian Weapons A-DAC 15 Complete Pistol Lower 5.56 SBA3 Brace

The Radian Weapons A-DAC 15 is a complete AR-15 pistol lower receiver built for 223 Remington and 5.56x45mm NATO. It uses a patented ambidextrous dual action catch (A-DAC) bolt hold-open system that lets right-handed shooters lock the bolt rearward without breaking their grip, plus ambidextrous magazine release buttons and a bolt release paddle.

The lower is machined from billet 7075-T6 aluminum with a Radian Black Cerakote finish. It includes an ambidextrous Talon 45/90 safety selector that converts between 90-degree and 45-degree throw without extra parts, and a SART self-adjusting receiver tensioner to reduce upper-to-lower wobble.

The package ships with an SB Tactical SBA3 pistol stabilizing brace, a Magpul K2 grip, a 6-position MIL-SPEC receiver extension with Radian QD end plate, and the extended bolt catch and takedown pin set. It fits AR-15 upper receivers and requires only an upper to complete a pistol build.
