Radian Weapons AX556 AR-15 Billet Black Stripped Lower

The Radian Weapons AX556 (also known as the A-DAC 15) is a premium fully ambidextrous AR-15 stripped lower receiver engineered for builders who want the most ergonomic and feature-rich foundation available for a custom AR-15 rifle or pistol.

Machined from a solid billet of 7075-T6 aluminum, the AX556 features an integral trigger guard and a flared magazine well for faster, more reliable reloads. The receiver is finished in Radian Black - a MILSPEC Type III hardcoat anodized base topped with a protective Cerakote coating for exceptional wear and corrosion resistance.

True ambidextrous controls are the heart of the AX556. The receiver comes equipped with a Talon 45/90 ambidextrous safety selector, an extended left-side bolt catch and release, a right-side bolt release, and a right-side magazine release - giving left- and right-handed shooters identical control layouts. Radian's proprietary Self-Adjusting Receiver Tensioner (SART) keeps the upper and lower locked together tightly without the wobble common to standard receivers, and enhanced takedown pins round out the premium package.

This is a stripped lower receiver only and does not include an upper, lower parts kit, pistol grip, trigger, stock, or magazine. Made in the USA and built to accept standard AR-15 pattern components in multi-caliber configurations, the Radian AX556 is the starting point for a top-tier custom build.
