Orthos Raider S4 12 GA 18.5" OD Green Shotgun

The Orthos Raider S4 is a gas operated semi auto 12 gauge, and this one wears OD Green Cerakote over an aluminum receiver. It chambers both 2 3/4" and 3" shells, and the magazine tube holds seven 2 3/4" shells or six 3" magnums. The 18.5" steel barrel is smooth bored and chrome lined, and it takes Benelli standard choke tubes, with a breacher choke in the box. A Picatinny rail runs along the top, and the aluminum handguard is M-LOK, with an angled three piece modular vertical grip attached.

Recoil goes into the patented SHOCK FORCE system built into the adjustable stock, and the cheek pad adjusts as well. Black River Manufacturing produces the furniture. For sights you get a ghost ring rear and the FIBERTRON front, a fiber optic sight lit by a small LED. The controls are sized up: an oversized charging handle, a large bolt release lever and an oversized safety, along with a spring assist ejector and a rubber overmolded grip. It weighs 9.5 lbs, has front and rear sling mounts and comes with a combat sling. Use shells running 1250 fps or faster, and plan on a 50 round break in with heavy high brass loads.
