Radian Model 1 Upper 18″ 6mm ARC – OD Green

Built to the most demanding standards in the industry, the Radian Model 1 18″ Upper in 6mm ARC and OD Green finish represents the pinnacle of precision rifle craftsmanship. Radian Weapons engineers every component with premium raw materials and processes each part on state-of-the-art CNC machining equipment, resulting in an upper receiver assembly that seamlessly blends exceptional form with real-world function.

The Model 1 features fully ambidextrous controls, making it equally capable in the hands of left- and right-handed shooters — a critical advantage in competitive, tactical, and hunting applications. Every upper is hand-assembled one at a time by a trained Radian gunsmith who personally inspects, test fires, and cleans the assembly before it ships, ensuring it meets Radian’s famously rigorous quality standards.

The 6mm ARC (Advanced Rifle Cartridge) chambering delivers an outstanding balance of long-range accuracy, flat trajectory, and manageable recoil — making this upper an excellent choice for precision rifle competitors, hunters pursuing medium to large game, and serious enthusiasts who demand more from their AR-platform builds. The 18″ barrel length maximizes velocity and ballistic performance from the 6mm ARC cartridge, while the OD Green finish offers a tactical, field-ready aesthetic.

Backed by Radian’s lifetime guarantee, this upper is a long-term investment in performance, reliability, and craftsmanship.
