Radian Weapons Model 1 Complete Upper Features The Radian Weapons Model 1 Complete Upper is built around an 18 match grade steel barrel with a black nitride finish 1:7 twist rate and 5/8x24 threading topped with a Dead Air KeyMo muzzle brake that transitions directly to compatible Dead Air suppressors for seamless suppressed fire in the 6mm ARC chambering. A rifle-length direct impingement gas system optimizes dwell time for the 18 barrel configuration for consistent reliable cycling across the full range of 6mm ARC loads. The Radian Raptor-SD suppressor-optimized ambidextrous charging handle ensures positive fluid charging from either side of the weapon for left- and right-handed shooters running cans or standard configurations. The complete 6mm ARC upper receiver is machined from billet 7075-T6 aluminum with M4 feed ramps and a lightweight forward assist topped with a proprietary 17 M-LOK aluminum handguard secured to the upper via an integrated stainless steel anti-rotation pin for a rigid zero-flex interface across the extended handguard length. Brown Cerakote finish covers all components for a cohesive corrosion-resistant field-ready aesthetic suited to hunting and outdoor long-range shooting applications and the sub-MOA accuracy guarantee with Black Hills match grade ammunition backs every hand-assembled unit. Radian s lifetime guarantee covers the Model 1 Complete Upper as a no-compromise 6mm ARC upper receiver for shooters who demand professional-grade long-range accuracy and suppressor-ready capability.
