Orthos Raider S4 N91 Elite 12 Gauge 18.5" Barrel - N91 Cerakote

Experience next-level recoil mitigation and rapid target acquisition with the Raider N91 Elite 12 Gauge Semi-Automatic Shotgun in N91 Cerakote. Engineered around a gas-operated semi-automatic action and built on a hardened T6 7075 aluminum receiver, the Raider N91 Elite features the patented SHOCK FORCE recoil system—delivering superior recoil reduction that makes firing heavy 3-inch magnum loads exceptionally comfortable. Paired with an 18.5-inch 4140 steel chrome-lined barrel accepting Benelli standard choke tubes, this tactical shotgun combines long-term durability with smooth, high-velocity cycling.

Designed in partnership with Black River Manufacturing, the Raider N91 Elite comes fully equipped with premium ergonomics and enhanced tactical controls. Highlights include an M-LOK aluminum handguard, an angled 3-piece modular vertical grip, an oversized charging handle, and an enhanced bolt release lever for effortless operation. Aiming is driven by a Ghost Ring rear sight paired with the patented FIBERTRON LED illuminated fiber-optic front sight for rapid low-light target alignment. Complete with a carbon fiber stock featuring an adjustable cheek pad, combat sling, breacher choke, and a 7+1 capacity (2.75" shells), this package is backed by a lifetime warranty.
