The billet-machined 7075-T6 upper and ADAC-15 lower are finished in Radian Black and built on the AR-15 platform. The kit is designated Multi caliber, giving builders flexibility when selecting a compatible barrel and components.
The ADAC-15 lower integrates a right-side bolt release and Radian’s A-DAC feature, which enables bolt hold-open via the magazine release. This control layout is part of the kit’s core design and is built into the receiver.
The 8.5 in free-float M-LOK aluminum handguard mates to the upper through a proprietary interface that uses a hardened steel anti-rotation pin. This system is engineered to secure the handguard-to-receiver union and is specific to this Model 1 configuration.
Radian’s ambidextrous Raptor-SD charging handle is included, complementing the receiver set and handguard. The kit ships as item R0435 and is designed and manufactured in Oregon, USA. As noted, it is not a complete firearm.
