Description
The Orthos Raider S4 Competition Highland Elite is a premium, competition-ready 12 gauge semi-automatic shotgun built around a gas-operated system and loaded with factory upgrades. This example features the striking Highland Camo Cerakote finish, 18.5" chrome-lined barrel, Crimson Trace red dot optic, and a camo sling.
Designed for speed and control, the Raider S4 Competition model includes an XL ambidextrous charging handle, enlarged loading port, fluted bolt, and QD sling mount on the left side of the receiver. Orthos also equips this shotgun with its patented SHOCK FORCE recoil system, helping reduce felt recoil and making even 3" magnum shells more manageable. The carbon fiber adjustable comb stock, adjustable cheek pad, and rubber overmolded grip help the shooter dial in a comfortable fit.
Additional highlights include a T6 7075 hardened aluminum receiver, M-LOK aluminum handguard, top-mounted Picatinny rail, ghost ring rear sight, and the patented FIBERTRON LED fiber optic front sight. Partnered with Black River Manufacturing for the furniture, this shotgun blends performance, durability, and standout styling into a serious competition or defensive platform.
This package includes the Crimson Trace red dot, camo sling, factory box, paperwork/manual, and accessories shown in the photos.
