Orthos Arms Raider S4 Elite Features The Orthos Arms Raider S4 Elite is built around a gas operated semi automatic system that cycles reliably across both 2 3/4 inch and 3 inch 12 gauge shells. The patented SHOCK FORCE recoil system integrated into the adjustable comb stock significantly reduces felt recoil letting shooters stay on target through fast strings of fire. An oversized charging handle and enlarged bolt release make manipulation quick even under stress or with gloved hands. The 18.5 inch chrome lined barrel resists corrosion and fouling keeping the action running cleanly through extended range sessions. Furniture from Black River Manufacturing includes an angled three piece MLOK vertical grip and a top mounted Picatinny rail for optics or lights. The FIBERTRON LED front sight adds a subtle glow to the fiber optic bead improving target acquisition in low light while the ghost ring rear sight offers a fast intuitive sight picture. An adjustable cheek pad lets shooters dial in a proper stock weld for consistent aim point after point. Rounding out the package is a combat sling and spare breacher choke tube for added versatility in the field.
