Radian Weapons R0847 A-DAC 15 Lower Receiver SBA3 Flat trigger Radian Black

The Radian Weapons R0847 A-DAC 15 Lower Receiver with SBA3 and flat trigger in Radian Black is a precision-engineered AR-15 lower receiver built from aircraft-grade aluminum. This is the critical foundation component for AR platform builds, machined to exacting tolerances to ensure reliable function, tight tolerances, and compatibility with standard upper receivers and parts ecosystem. The integrated enhanced controls and robust engineering make it the choice for shooters who demand consistency across thousands of rounds.

The aircraft-grade aluminum construction provides exceptional strength-to-weight performance while resisting corrosion and handling the pressures of centerfire rifle operation. The flat trigger profile enhances trigger control and reset speed compared to curved designs, reducing lock time and allowing faster target transitions during precision work or defensive scenarios. The included SBA3 brace assembly addresses the needs of short-barreled platform builders and users seeking ergonomic stability. At 4.14 lbs, the lower receiver provides a weight baseline that remains compatible with a wide range of upper assemblies and rail systems, allowing builders to optimize their overall system weight without sacrificing structural integrity.

This lower receiver is purpose-built for competitive shooters, law enforcement armorer builds, and civilian operators who prioritize accuracy and durability. Whether configuring a precision rifle platform, a home defense carbine, or a duty-quality build, the R0847 provides a proven foundation that accepts standard AR-pattern magazines, stocks, and receivers. The flat trigger facilitates controlled, repeatable breaks essential for distance shooting or tactical accuracy requirements. Builders working with Radian Weapons components benefit from quality control standards and dimensional consistency that minimize fitment issues during assembly.
