The Radian Weapons Model 1 Upper and Handguard Set is a precision-engineered foundation for high-end AR-15 builds. CNC-machined from a matching set of 7075-T6 billet aluminum, both components are finished in a durable Radian Black Cerakote. This multi-caliber compatible set includes a 14 free-float handguard featuring the Magpul M-LOK mounting system and a stainless steel anti-rotation pin for a rigid, no-flex interface. The assembly comes pre-installed with a lightweight forward assist, dust cover, and a Raptor-SD suppressor-optimized ambidextrous charging handle, ensuring every surface is chamfered for a smooth, snag-free finish. Note: The Raptor-SD charging handle included in this set features a ported shaft designed to redirect gasses down and away from the shooter's face when firing with a suppressor.
