R0480 .223 Wylde 17.5" FDE The design philosophy behind the Radian Model 1 is simple: use the highest quality raw materials, most precise CNC machining equipment, and best components available to create a weapon that seamlessly blends form and function. Beyond quality and aesthetics, the Model 1 features fully ambidextrous controls, adding much-needed utility for both left and right handed shooters. Every Model 1 is assembled by hand, one at a time, by a trained gunsmith who inspects, test fires, and cleans the weapon to personally guarantee it meets the most rigid quality standards. No detail has gone overlooked, which is why the Model 1, like every Radian product, is guaranteed for life.
