Description
Product Overview
The Radian Weapons A-DAC 15 Ambidextrous Lower Receiver (OD Green) sets the benchmark for full-ambidextrous AR-15 ergonomics and billet machining precision. Machined from aircraft-grade 7075-T6 billet aluminum, this premium lower receiver combines an oversized flared magazine well, an integrated trigger guard, and Radian's durable Olive Drab Green anodized finish.
At the center of its design is the patented A-DAC (Ambidextrous Dual Action Catch) system, which allows shooters to lock the bolt to the rear without taking their dominant firing hand off the grip. Simply draw the charging handle back while depressing the right-side magazine release button to lock the bolt. Outfitted with pre-installed Radian Talon 45/90 ambidextrous safety selectors, enhanced takedown pins, and a Self-Adjusting Receiver Tensioner (SART), the A-DAC 15 delivers an ultra-stable, duty-grade platform.
FFL Required: This item is a regulated firearm component (serialized lower receiver). Shipment must be directed to a licensed Federal Firearms Licensee (FFL) dealer for in-person background check and transfer in accordance with federal and state laws.

Frequently Asked Questions
How does the patented A-DAC (Ambidextrous Dual Action Catch) work?
The A-DAC system links the right-side magazine release button to the bolt catch mechanism. To lock the bolt open without taking your hand off the pistol grip, pull the charging handle back while holding down the right-side magazine release button, then release the charging handle.
Are proprietary lower receiver parts included with the Radian A-DAC?
Yes. All proprietary hardware comes pre-installed or supplied in the package, including the extended bolt catch, left-side magazine release paddle, right-side magazine release button, right-side bolt release paddle, hammer pin, SART tensioner, and Radian Talon safety selector.
What is the function of the SART (Self-Adjusting Receiver Tensioner)?
The SART is a spring-loaded plunger located inside the lower receiver rear lug pocket. It constantly exerts tension against the upper receiver's rear pin lug to eliminate upper/lower receiver slop and wobble without binding the takedown pin.
Is this lower receiver compatible with standard AR-15 upper receivers and triggers?
Yes. The A-DAC 15 accepts standard mil-spec dimension upper receivers and aftermarket triggers (such as Geissele, TriggerTech, and Timney).
