Key Features

• 18″ Match-Grade Barrel: Why it matters — delivers sub-MOA accuracy at extended ranges, making it ideal for precision shooting and varmint hunting.
• Ambidextrous Controls: Why it matters — left-handed shooters get the same speed and leverage as right-handed users without swapping parts.
• SB Tactical SBA3 Brace: Why it matters — offers a stable shooting platform while maintaining legal pistol configuration, with adjustable length of pull.
• Cerakote Flat Dark Earth Finish: Why it matters — resists corrosion, scratches, and harsh weather, keeping the rifle looking field-ready for years.
• Gunsmith-Inspected Assembly: Why it matters — each rifle is hand-checked by a trained Radian gunsmith, reducing the chance of out-of-spec tolerances.

Who It’s For

This rifle is built for the traditional shooter who values precision and reliability over flash. It suits competitive shooters in PRS or NRL Hunter matches, hunters after coyote or deer at moderate distances, and collectors who appreciate Radian’s fit-and-finish. If you want a do-it-all rifle that runs 6mm ARC hard without sacrificing comfort, this is your rig.

Pros & Cons

• Pros: Match-grade accuracy, full ambidextrous operation, durable Cerakote finish, SBA3 brace improves shooting stability, gunsmith-inspected build.
• Cons: Higher price point — you pay for the precision and brand reputation. The 6mm ARC round is less common than 5.56 or .308, so ammo availability can be spotty in some regions.

The Radian Model 1 stands out with its full ambidextrous controls and 18″ barrel, giving you longer sight radius and higher velocity than the Geissele. The Zev OZ-9 is a pistol, not a direct competitor, but shows the price difference for a premium handgun. The Radian is built for precision rifle work — the Zev is for duty carry.
