The Radian Model 1 Upper Receiver and Hand Guard are precision CNC machined as a matching set, structurally reinforced in critical areas for improved strength and rigidity. The upper receiver is cut from billet 7075-T6 aluminum and assembled with dust cover, hand guard anti-rotation pin, light weight forward assist, and Raptor-SD Ambidextrous Charging Handle. The hand guard features Magpul M-LOK accessory mounting slots that attach to the barrel nut using four steel cross bolts coated in black nitride for corrosion resistance. Every surface has been precision machined and chamfered to ensure no uncomfortable, sharp edges can be found. The upper and hand guard are then sprayed with Radian Cerakote options for a perfectly matching finish.
