Radian Weapons Model 1 Complete Upper 6mm ARC 18" M-LOK

The Radian Weapons Model 1 is a complete AR-15 upper receiver kit chambered in 6mm ARC, built around an 18" barrel with a 1:7 twist rate. The upper is finished in Cerakote Brown and manufactured to tight CNC tolerances using premium raw materials, with hand assembly and inspection by a trained gunsmith. The gas system length is consistent with a rifle-length setup suited for an 18" barrel operating via direct impingement. A free-float M-LOK handguard is included, providing a modern, lightweight rail attachment system. The upper ships with an ambidextrous control set integrated into the receiver design.
