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. • Sub-MOA Accuracy Guarantee w/ Black Hills Match Grade Ammunition • Billet Machined 7075-T6 Upper Receiver w/ M4 Feed Ramps • Proprietary Extended Aluminum Handguard w/ Magpul M-LOK Modular Mounting System and Integrated Upper/Handguard Stainless Steel Anti-Rotation Pin • Chambered in 6mm ARC • 5/8X24 Thread Pitch • Enhanced Black Nitride M16 Bolt Carrier Group • Lightweight Forward Assist • Radian Raptor-SD Suppressor-Optimized Ambidextrous Charging Handle • Direct Impingement Gas System • 18 Rifle Length Gas System
