Radian Weapons ADAC-15 Complete Pistol Lower Receiver Radian Black

The Radian ADAC-15 Complete Pistol Lower in Radian Black is a premium, ambidextrous foundation for AR-style pistol builds and compact rifles. Machined from billet 7075-T6 aluminum with an integral trigger guard and flared magazine well, it’s engineered for durable, repeatable function and exceptional ergonomics. The patented A-DAC (Ambidextrous Dual-Action Catch) lets right-hand shooters lock the bolt to the rear without moving off fire control speeding reloads and improving control under stress. Factory-included hardware and thoughtful attention to fitment mean this lower gets you closer to a finished, reliable build faster.

Radian blends purposeful features A-DAC right-side bolt hold, Talon ambidextrous 45/90 safety selectors, left-side magazine release paddle, and right-side bolt release with precision machining and anti-wobble tech (SART spring-loaded plunger). The result is a ready-to-run lower that reduces play, improves ergonomics for bilateral shooters, and ships with the proprietary parts needed for swift assembly.
