The matched billet upper and lower receivers are CNC-machined from 7075-T6 aluminum and finished in FDE for a uniform colorway across the set. The lower is marked "MULTICAL" for caliber flexibility, and the kit is built around the AR-15 direct-impingement platform.
Radian's A-DAC system enables right-side bolt lock-back and release via the magazine-release interface, working in concert with the ambidextrous magazine release and an extended bolt catch for streamlined manipulation. The included Talon ambidextrous safety selector is configurable for either 45° or 90° throw.
The upper receiver features a forward-assist delete (no forward assist), shell deflector, and a continuous top Picatinny rail. The 15.5 in aluminum handguard provides extended coverage, an M-LOK interface for accessory mounting, and a full-length top rail for uninterrupted alignment from receiver to handguard.
Manufactured in Oregon, USA, this kit accepts standard AR-15 direct-impingement components, making it a strong foundation for a premium build. It ships in the original factory box with a fitted foam insert and includes a barrel nut wrench to support installation.
