If you're building an AR with left-hand capability in mind, or you're a righty who wants lightning-fast control without breaking your grip, the Radian A-DAC 15 arrives ready to handle it. This stripped lower receiver starts with billet 7075-T6 aluminum machined to Radian's exacting standards, giving you a rock-solid foundation that won't flex or wobble under any conditions.
Every control on this lower speaks the language of versatility. The Talon ambidextrous safety selector moves smoothly from either side. A left-side magazine release paddle and right-side bolt release let both handed shooters operate the gun without fumbling or changing their shooting grip. The integrated trigger guard is built directly into the lower itself, and the flared magazine well opens up quick, sure reloads whether you're at the range or running drills.
Radian's self-adjusting receiver tensioner (SART) is a spring-loaded plunger that seats inside the lower. It does one critical job: it kills that frustrating upper-to-lower wobble that comes from wear, loose tolerances, or just the nature of mil-spec builds. The patented A-DAC system is where this receiver really shines. Right-handed users can lock the bolt to the rear by pulling the charging handle back, pressing the right-side magazine release, then releasing the charging handle. You stay in control the whole time.
Radian included every piece you need to finish the job: extended bolt catch, left-side magazine release paddle, right-side magazine release button, right-side bolt release paddle, enhanced takedown pins, and hammer pin. The Talon 45/90 safety comes in both long and short versions so you can pick what works for your hand. That's a complete package from a company that sweats the details.
The patented A-DAC (Ambidextrous Dual Action Catch) allows right-handed users to lock the bolt to the rear without moving their hand off the fire control area. You simply pull the charging handle back, press the right-side magazine release, and release the charging handle. On standard lowers, you'd need to reach back for a traditional bolt catch release with your thumb or relocate your grip.
Yes, the A-DAC 15 is compatible with standard mil-spec AR-15 upper receivers and most aftermarket components. It shares the same magazine well interface and fire control group dimensions as traditional AR-15 lowers, so your trigger pack, hammer, and springs will fit without modification.
No, this is a stripped lower receiver. It comes with the Talon safety, all the hardware needed for assembly, enhanced takedown pins, and the proprietary controls, but you'll need to source a fire control group (trigger, hammer, springs) separately to complete it.
The SART is a spring-loaded plunger that takes up the space between the upper and lower receiver. It automatically adjusts to remove wobble and keep the receivers tight without over-tightening. This reduces wear on both receivers and creates a more stable platform for accuracy and longevity.
Absolutely. The safety selector, magazine release, and bolt release are all fully ambidextrous, so the controls sit on both sides. Left-handed shooters get the same smooth, efficient operation as right-handed users, and they don't have to work around gun-specific design compromises.
The A-DAC 15 comes in Radian Black Cerakote, a high-performance ceramic coating that resists corrosion, impacts, and wear far better than standard anodizing. Cerakote is a firearms-industry standard for durability and longevity.
