Orthos Arms Raider S4, 12ga, 18.5" Barrel, 3" Chamber, 7+1 Capacity, OD Green, Semi-Auto Shotgun

Orthos Arms Raider S4, 12ga, 18.5" Barrel, 7+1, OD Green Cerakote Semi-Auto Shotgun

The Orthos Arms Raider S4 OD Green brings thoughtful comfort and sighting features to a full-featured semi-automatic 12 gauge. An 18.5-inch chrome-lined barrel and gas-operated action provide the foundation, while the SHOCK FORCE recoil system and adjustable cheek pad help make the shotgun more comfortable to spend time with. OD Green Cerakote gives the finished package a distinctive, understated appearance.

The Raider holds 7+1 rounds with 2-3/4-inch shells or 6+1 with 3-inch shells. A FIBERTRON LED-assisted fiber-optic front sight, ghost-ring rear sight, aluminum M-LOK handguard and oversized controls are included in the configuration. If you want a semi-auto shotgun with the furniture and sighting details already in place, the Raider S4 offers plenty to appreciate.

An 18.5-Inch Chrome-Lined Barrel and Versatile Chamber

The Raider's 18.5-inch barrel is made from 4140 steel with a chrome-lined smooth bore. Its 3-inch chamber accepts suitable 2-3/4-inch and 3-inch 12-gauge shells, providing flexibility when selecting ammunition for range use. The gas-operated action cycles automatically, with a spring-assist ejector included in the operating system.

The magazine tube holds seven 2-3/4-inch shells or six 3-inch shells, with one additional shell in the chamber. That distinction makes capacity clear for either shell length. A breacher-style choke tube comes with the shotgun, and the barrel uses the Benelli Standard choke interface for compatible choke selection.

SHOCK FORCE Recoil Furniture for a More Comfortable Fit

The adjustable stock incorporates Orthos' patented SHOCK FORCE recoil system, designed to soften felt recoil at the shoulder. It is a useful feature on a 12 gauge, especially when you want to enjoy an extended range session. The adjustable cheek pad adds another way to tailor the contact point between you and the shotgun.

Furniture developed with Black River Manufacturing continues that attention to the points you touch. A rubber-overmolded grip supplies a textured, cushioned contact surface. At the handguard, the angled three-piece modular vertical grip and M-LOK rail grips let you shape a comfortable hold around the Raider's front end.

FIBERTRON Illumination and Ghost-Ring Sights

The FIBERTRON front sight adds a small LED to a fiber-optic aiming element. The LED provides a subtle glow, helping the front reference remain visible when ambient light is less favorable for an unassisted fiber optic. A ghost-ring rear sight completes the sighting arrangement.

The top Picatinny rail also gives you a defined mounting interface for a compatible optic and mount. You can begin with the included sights and select an optic around your preferences. The sight system and rail make the Raider easy to configure for the kind of range experience you enjoy.

Oversized Controls and Aluminum Construction

An oversized charging handle, oversized safety switch and large enhanced bolt-release lever provide generous contact surfaces. Those details are easy to appreciate during normal handling, especially when smaller controls feel fiddly. The enhanced trigger is part of a configuration that gives attention to more than the barrel and finish.

A hardened 7075-T6 aluminum receiver supports the action, paired with an aluminum M-LOK handguard. OD Green Cerakote unifies the exterior, while M-LOK slots provide places for compatible accessories. Front and rear sling mounts work with the included combat sling, so a carrying setup is part of the package.
