The Radian Weapons Radian Upper 18" 6mm Arc Brown is a complete upper assembly built around the proven Model 1 design, blending precise machining with a sleek, extended handguard. Its 18" barrel is chambered in 6mm Arc and capped with a Dead Air KeyMo muzzle brake, while the long M-LOK handguard and ambidextrous Raptor-SD charging handle support smooth handling and accessory mounting.
This upper is well suited for precision range work, training, and hunting where the efficient 6mm Arc cartridge and sub-MOA accuracy guarantee can be fully appreciated. The rifle-length gas system, enhanced M16 bolt carrier group, and billet 7075-T6 receiver work together for consistent performance and soft recoil characteristics. It is a refined option for shooters who value Radian Weapons’ careful craftsmanship and attention to detail.
