Overview

For shooters building a precision AR-style platform, control and ergonomics can make the difference between a good shot and a great one. Ambidextrous controls, durable materials, and machining tolerances that support consistent builds are priorities for serious users and custom builders alike.

RADIAN WEAPONS A-DAC 15 LOWER RECEIVER is a stripped lower receiver machined from billet 7075-T6 aluminum and finished in a custom gray Cerakote. The receiver integrates fully ambidextrous controls and the patented A-DAC (Ambidextrous Dual Action Catch), enabling right-handed shooters to lock the bolt to the rear without taking their hand off the fire control area.

Key features and why they matter

Billet 7075-T6 construction

The lower is machined from billet 7075-T6 aluminum, offering superior strength-to-weight over cast or forged alternatives. For builders focused on long-term durability and tight tolerances, that material choice supports reliable component fitment and consistent performance under repeated use.

Patented A-DAC system

The A-DAC (Ambidextrous Dual Action Catch) is the headline feature: it allows a shooter to lock the bolt to the rear without breaking grip or transitioning hands. That single-handed bolt lock capability improves reload speed and weapon manipulation for both training and tactical scenarios.

Ambidextrous controls and Talon selector

Fully ambidextrous controls and the included Talon ambidextrous safety selector make this lower a natural choice for left- and right-handed shooters, competition rigs, or rigs shared between users.

Compatibility and finish

Multi-caliber rated and compatible with standard mil-spec upper receivers, this lower gives builders flexibility when selecting barrels and bolt carrier groups. The custom gray Cerakote finish resists corrosion and provides a clean, professional appearance straight out of the box. The manufacturer-suggested price is $514.95.
