Overview

The Orthos Arms Raider S4 is a gas-operated semi-automatic 12-gauge shotgun featuring an 18.5-inch 4140 full steel smooth chrome-lined barrel with a Benelli-standard thread pattern and a included breacher choke tube. Built on a T6 7075 hardened aluminum receiver with an Alpine Camo Cerakote finish, it utilizes a top-mounted Picatinny rail and an M-LOK aluminum handguard paired with an angled 3-piece modular vertical grip. Designed for heavy use, the shotgun incorporates a patented SHOCK FORCE recoil system and an adjustable cheek pad integrated into the carbon fiber adjustable stock to manage 3-inch magnum shells comfortably.

Sighting is handled by a ghost ring rear sight and a patented FIBERTRON LED front sight that provides a subtle glow to the fiber optic element. Additional features include an advanced trigger, oversized charging handle, large enhanced lever bolt release, oversized safety switch, spring-assist ejector, front and rear sling mounts, and an included combat sling.
