Orthos Raider S4 Features The Orthos Arms Raider S4 runs on a gas operated semi automatic system that cycles both 3 and 2-3/4 shells giving the shooter a single platform that adapts to whatever ammunition is on hand. The 4140 full steel barrel is smooth chrome lined for corrosion resistance and consistent patterning and it is fitted with a Benelli standard choke for versatility across loads. The patented SHOCK FORCE adjustable stock absorbs recoil impulse directly in the stock allowing comfortable follow up shots even with full 3 magnum shells. An adjustable cheek pad lets the shooter dial in a proper sight picture regardless of build or the optic mounted to the top rail. The receiver is machined from T6 7075 hardened aluminum and finished in OD Green Cerakote for a durable low maintenance exterior that resists wear in the field. An angled three piece modular vertical grip with M-LOK slots an oversized safety switch an advanced oversized charging handle and a large enhanced bolt release round out controls built for fast deliberate operation under stress. The FIBERTRON LED fiber optic front sight pairs with a ghost ring rear sight for quick target acquisition in low light and the shotgun ships with a combat sling a breacher choke tube and an owners manual. At 9.5 lbs and 40 overall with the stock collapsed the Raider S4 is built for shooters who want a tactical shotgun ready to run straight out of the box.
