For operators and serious builders, the lower receiver is the foundation of AR-15 performance and ergonomics. A well-designed lower can streamline manipulations, speed reloads, and reduce the need for awkward hand movements under stress. The RADIAN WEAPONS AX556 LOWER RECEIVER answers those demands with machine-grade materials and a purpose-built ambidextrous control layout.

Precision Machining and Materials

Machined from billet 7075-T6 aluminum, this lower offers a rigidity and finish that stamped or cast lowers can’t match. The choice of 7075-T6 is deliberate: it provides high tensile strength and durability while maintaining a weight profile suitable for duty and competition rifles. At a listed price of $514.95, the AX556 sits in the premium tier where fitment and longevity matter.

Ambidextrous Controls Built for Speed

Where the AX556 stands out is its fully ambidextrous design. The Talon Ambidextrous Safety Selector provides left- and right-side access to safe and fire positions. The left-side magazine release and right-side bolt release are positioned for intuitive reach.

A-DAC: Ambidextrous Dual Action Catch

The patented A-DAC (Ambidextrous Dual Action Catch) is a tactical-level innovation. It enables right-handed shooters to lock the bolt to the rear without removing their support hand from firing control — a significant advantage when performing transitions or conducting rapid reload drills.

Included Hardware and Compatibility

Everything you need for the ambidextrous setup ships with the lower: extended bolt catch, left-side magazine release paddle, right-side magazine release button, right-side bolt release paddle, and hammer pin. That proprietary hardware streamlines installation and keeps the build clean. As a member of the Lower Receivers category, it’s intended for AR-15-style builds and pairs well with standard mil-spec components.
