The Radian Weapons Radian Upper 14.5" 6mm ARC Brown is a complete Model 1 upper built for shooters who want premium accuracy and refined handling in a compact AR-15 package. Centered around a 14.5-inch 6mm ARC barrel with a pinned Dead Air KeyMo flash hider for a 16-inch overall length, it combines a billet 7075-T6 upper receiver, extended M-LOK handguard, and Radian’s enhanced bolt carrier group for smooth, reliable operation.

This upper is well suited for precision-focused range work, competition-style builds, and hunting where the 6mm ARC cartridge’s reach and efficiency shine. The mid-length gas system and Raptor-SD charging handle help keep the shooting experience soft and controllable, while the brown Cerakote finish offers a distinctive, durable look. It is a strong choice for AR-15 owners who value Radian’s attention to detail, careful assembly, and long-standing reputation for high-end components.
