The Orthos Arms Raider S4 Chisel Elite is a gas-operated, semi-automatic 12 gauge shotgun built for shooters who want a fast-handling, modern scattergun that is ready to run straight out of the box. It pairs an 18.5 in. chrome-lined barrel with a hardened aluminum receiver, an M-LOK handguard, a collapsible Chisel stock and a long list of enhanced controls. The goal behind the Raider S4 is simple: put the upgrades most owners would add later into the gun from the start, so it is ready for home defense, 3-gun style practice or general field use the day it comes home. Recoil Control You Can Feel The heart of the Raider S4 is the patented SHOCK FORCE recoil system, which comes standard on every gun. It is designed to soak up felt recoil so that even 3 in. magnum shells stay comfortable to shoot. Combined with the gas-operated action, it helps keep the muzzle steadier between shots, which means faster follow-up shots and less fatigue over a long range session. The shotgun chambers both 2-3/4 in. and 3 in. shells, so it handles everything from light target loads to full-power buckshot and slugs. Chisel Stock and Adjustable Fit The Chisel Elite takes its name from the Chisel stock. The furniture was developed in partnership with Black River Manufacturing, and the stock includes a built-in plate for mounting an RMR-footprint red dot. An adjustable cheek pad lets you set your head position for a consistent cheek weld, whether you are using the sights or an optic. With the stock collapsed the shotgun measures 40 in. overall, a handy length for moving through a house or getting in and out of a vehicle. A skeletonized, rubber overmolded grip gives a secure hold with wet or gloved hands. Sights and Optics Ready Out of the box the Raider S4 uses a ghost ring rear sight with the patented FIBERTRON LED front sight. A small LED gives the fiber optic front sight a subtle glow, so it stays easy to pick up in dim light where a plain fiber optic fades out. A top-mounted Picatinny rail runs along the receiver for a red dot, magnified optic or other accessory, and the stock plate offers another way to run an RMR-footprint dot. Built From Quality Materials The receiver is machined from T6 7075 hardened aluminum, which keeps weight in check without giving up strength. The 18.5 in. barrel is 4140 steel, smooth bored and chrome lined for corrosion resistance and easier cleaning. It accepts Benelli-standard choke tubes, a widely available pattern that makes it easy to tune the gun for buckshot, slugs or birdshot. The aluminum M-LOK handguard gives you plenty of room to add a weapon light, a vertical grip or other accessories. Front and rear sling mounts come standard, and a combat sling is included. Enhanced Controls Orthos fits the Raider S4 with the kind of controls that usually come as aftermarket upgrades. The advanced oversized charging handle and large enhanced bolt release make loading and clearing the gun effortless, even under stress. An oversized safety switch is easy to find and work by feel. The advanced trigger offers a clean, predictable press, and a spring-assisted ejector throws empties clear for reliable cycling. Capacity The tube holds 6+1 rounds of 3 in. shells or 7+1 rounds of 2-3/4 in. shells, giving you plenty of on-board capacity for a defensive or competition shotgun. At 9.5 lbs, the gun has enough weight to help settle recoil while staying easy to carry and point.
