Radian A-dac 15 Lower Receiver

The Radian A-DAC 15 Lower Receiver represents precision engineering for AR-15 platform builders and tactical professionals who demand reliability without compromise. Designed as a fully regulated firearm component, this lower receiver serves as the serialized foundation for complete rifle builds, custom configurations, and modular weapon systems used in law enforcement, military training, and civilian tactical applications. The A-DAC designation reflects Radian Weapons' commitment to ambidextrous functionality and enhanced ergonomics—critical features for operators who require seamless platform operation across varied mission profiles and shooting positions.

Built with mil-spec dimensional compliance, the A-DAC 15 lower receiver integrates Radian's renowned ambi-controls architecture, enabling left and right-handed shooters to operate controls without grip repositioning or manual manipulation of safety levers. The receiver features a hard-coat anodized finish that resists corrosion, wear, and finish degradation in field environments—essential for operators exposed to moisture, sand, and extended use cycles. Weighing 1.5 lbs and measuring 7 x 3.5 x 11 inches, the lower receiver maintains a compact footprint while providing full ergonomic surface area, allowing installation of ambidextrous charging handles, mag releases, and safety selectors that transform the rifle into a truly ambi-configured weapon system.

This lower receiver is compatible with mil-spec upper receivers and AR-15 components, making it ideal for shooters building duty rifles, competition platforms, or tactical home-defense systems. Installation requires proper upper receiver mating, trigger group assembly, and compliance with federal and local firearms regulations—professional gunsmithing or licensed FFL oversight is recommended for those unfamiliar with lower receiver assembly. Whether you're a seasoned armorer customizing a patrol rifle or a civilian builder seeking ambi-accessibility for improved handling, the Radian A-DAC 15 delivers the precision and control expected from a purpose-built tactical receiver.
