Radian Weapons AR-15 Upper Features The Radian Weapons Upper/Handguard Set pairs a billet 7075-T6 aluminum upper receiver with a matching 14 inch M-LOK handguard machined as a set so the fit and finish line up perfectly. Both pieces are structurally reinforced in critical areas giving the assembly added strength and rigidity over a standard forged upper. The upper comes complete with a dust cover lightweight forward assist and handguard anti-rotation pin already installed. Topping it off is the Radian Raptor-SD ambidextrous charging handle giving left and right handed shooters equally fast positive manipulation of the bolt carrier group. The handguard attaches to a 7075-T6 aluminum barrel nut using four steel cross bolts washers and nuts all coated in black nitride for corrosion resistance under hard use. Magpul M-LOK slots run the length of the handguard for mounting lights grips bipods and other accessories wherever the build calls for them. Every machined surface is chamfered during production so no sharp edges are left to catch gear or hands during use. Finished together in a matching Olive Drab Green Cerakote the Radian Weapons Upper/Handguard Set gives builders a cohesive duty grade foundation for an AR-15 build.
