MDT Oryx Mossberg Patriot Long Action Chassis – Black
The MDT Oryx 104905-BLK gives the Mossberg Patriot Long Action a rigid, adjustable chassis platform for shooters building a more capable hunting, long-range, or precision rifle.
By replacing the conventional factory stock with an aluminum chassis system, the Oryx provides a more stable foundation for the action along with adjustable ergonomics, AICS-pattern magazine compatibility, and modern accessory mounting.
A Stronger Foundation for the Mossberg Patriot
The Oryx chassis supports the rifle action in a rigid aluminum structure designed to provide a consistent interface between the action, stock, and shooter.
For Patriot owners looking to move beyond a traditional hunting stock, it offers a straightforward path into a modern precision-rifle configuration without requiring a fully competition-focused chassis.
- Rigid aluminum chassis construction
- Adjustable cheekpiece
- Adjustable length of pull
- M-LOK accessory mounting
- AICS-pattern magazine compatibility
- Ambidextrous magazine release
- Integrated barricade-style magwell
- Interchangeable grip design
Built for Hunting & Long-Range Shooting
The Mossberg Patriot is commonly used as a practical hunting rifle, and the Oryx gives the platform more adjustability and accessory support without losing that field-oriented purpose.
The adjustable cheekpiece helps establish consistent alignment behind larger optics, while the M-LOK forend provides mounting points for bipods, sling hardware, and other field accessories.
For longer-range shooting, the more rigid chassis foundation and repeatable stock geometry make it easier to build a rifle around stable prone, bench, tripod, and supported field positions.
Room to Build Toward Positional Shooting
The Oryx also gives the Patriot room to grow beyond a basic hunting setup.
Adding an ARCA rail, forend weights, rear weight, and a precision bipod can move the rifle toward a more positionally capable setup for practical long-range shooting and competition-style training.
