The Orthos Arms Raider S4 FDE 12 gauge semi-auto shotgun delivers elite-level performance in a rugged, flat dark earth finish that blends seamlessly into tactical environments.

The adjustable carbon fiber stock includes a customizable cheek pad for a perfect fit, while the gas-operated semi-automatic action ensures reliable cycling across various ammunition types, from light target loads to full-power defense rounds. Paired with premium Black River Manufacturing furniture, this shotgun offers exceptional ergonomics and modularity straight from the factory.

Built for demanding use, the Raider S4 FDE boasts a durable T6 7075 hardened aluminum receiver, an 18.5" chrome-lined 4140 steel barrel with Benelli-standard choke compatibility (including the included breacher choke), and an M-LOK aluminum handguard topped with a Picatinny rail for optics and accessories. Key enhancements include an oversized advanced charging handle, large enhanced bolt release lever, spring-assisted ejector, rubber overmolded grip, angled 3-piece modular vertical grip with M-LOK rail sections, front and rear sling mounts, and an oversized safety switch. The patented FIBERTRON LED front sight provides a subtle, battery-powered glow to the fiber optic for lightning-fast target acquisition in any lighting condition, backed by ghost ring rear sights for precision.

Weighing just 9.5 lbs with a collapsed length of 40", the Raider S4 FDE maintains excellent balance and maneuverability, offering 6+1 capacity for 3" shells or 7+1 for 2¾" shells.
