MDT Oryx Ruger American Long Action Chassis – Arctic Snow Camo
Upgrade your Ruger American Long Action into a more capable precision rifle with the MDT Oryx 116677-ASC, finished in our custom Arctic Snow Camo Cerakote.
The Oryx combines the rigidity, adjustability, and modularity of an aluminum chassis with a straightforward design that works just as well for hunting and recreational long-range shooting as it does for positional and competition use.
For Ruger American Long Action owners, it provides a substantial step beyond the factory stock while allowing the rifle to remain as simple or become as specialized as the shooter wants.

Custom Arctic Snow Camo Cerakote
The Arctic Snow Camo finish gives the 116677-ASC a crisp, high-contrast custom appearance built around lighter winter-inspired tones.
This is a custom Cerakote finish applied to the Oryx platform while retaining the same aluminum chassis structure, adjustable ergonomics, AICS-pattern magazine compatibility, and M-LOK accessory mounting underneath.
It is an excellent option for shooters who want something distinctly different from MDT's standard Black, Gray, FDE, and ODG finishes while keeping the proven functionality of the Oryx system.
Oryx Performance for the Ruger American Long Action
The 116677 brings the familiar Oryx chassis system to the Ruger American Long Action, giving shooters a rigid foundation for hunting, long-range, and precision-oriented builds.
The action is supported by an aluminum V-block bedding system while the barrel remains free floated, helping eliminate the flex commonly associated with lightweight factory stocks.
Adjustable cheek height and length of pull allow the rifle to be fitted around the shooter and optic, creating a more repeatable position behind the rifle.
Precision, Value & Performance
The Oryx is designed to deliver the core advantages of a modern precision chassis without requiring the shooter to move immediately into a heavier and more expensive dedicated match platform.
Its aluminum structure provides a rock-solid foundation for the barreled action, while the free-floated forend, adjustable buttstock, detachable-magazine system, and accessory mounting give the Ruger American significantly more room to grow.
That combination makes the Oryx particularly strong for shooters building a capable rifle around an affordable factory action.
Start with the Chassis. Build from There.
One of the biggest advantages of the Oryx is its modular add-on design.
A basic rifle can remain relatively clean with a bipod and magazine, or the chassis can be expanded with a full-length ARCA rail, exterior weights, rear weight, sling hardware, tool-less cheek adjustments, and other accessories.
You invest in the features that actually benefit the rifle rather than paying for everything up front.
Long-Action Capability
The Ruger American Long Action allows the Oryx platform to support the longer cartridges commonly chosen for hunting and long-range shooting.
The rigid chassis foundation, adjustable shooter fit, detachable-magazine system, and generous barrel clearance make it well suited to heavier precision barrels, larger optics, and field-oriented long-range builds.
Competition, Hunting & Long Range
The Oryx works across a wide range of shooting disciplines.
For positional and PRS-style shooting, the rigid chassis and integrated barricade stop provide consistent contact against bags, barricades, and other props.
For long-range shooting, the adjustable cheekpiece and length of pull help establish consistent eye alignment and shoulder position behind the optic.
For hunting, the rifle can remain relatively simple without unnecessary weights or competition accessories while still benefiting from the rigid aluminum bedding structure and adjustable fit.
M-LOK Accessory Mounting
The Oryx includes M-LOK mounting along the underside of the forend, providing attachment points for bipods, accessory rails, weights, sling hardware, bag riders, and other compatible equipment.
Optional Oryx side panels can further expand exterior accessory and weight mounting as the rifle's intended use changes.
Add Full-Length ARCA
For shooters using ARCA-compatible bipods, tripods, barricade equipment, or positional shooting supports, the Oryx can be upgraded with a full-length ARCA rail.
The Pete's Pillars full-length Oryx ARCA rail extends along the bottom of the forend and also adds integrated QD sling cups.
It is one of the most useful upgrades for turning a basic Oryx into a more capable long-range or positional shooting platform.
Tune the Rifle's Balance
The Oryx platform allows additional weight to be positioned where it actually benefits the rifle.
Exterior M-LOK forend weights can move the balance point forward, while the Pete's Pillars replacement aluminum rear buttstock weight can add mass toward the rear.
This allows a competition-oriented rifle to be tuned around bags and barricades while a hunting rifle can simply leave those components off and remain lighter.
Adjustable Shooter Fit
The Oryx buttstock includes adjustment for both cheek height and length of pull.
These adjustments allow the rifle to be fitted around the shooter's body, optic height, and preferred shooting position rather than forcing the shooter to adapt to a fixed factory stock.
Optional cheek-riser wheel knobs can also provide faster, tool-less cheekpiece adjustment.
AICS-Pattern Magazine Compatibility
The 116677-ASC Ruger American Long Action uses long-action AICS-pattern magazines, providing access to a widely supported detachable-magazine system.
Magazine selection should be matched to the specific cartridge and rifle configuration.
Heavy-Barrel Friendly
The Oryx provides clearance for barrels up to approximately 1.25 inches in diameter, making it suitable for many heavier hunting, target, and precision barrel profiles.
The barrel remains free floated throughout the forend, helping prevent stock or chassis pressure from interfering with the barrel.

Build Out Your Ruger American Oryx

For Ruger American Long Action owners, that means a factory rifle can become a substantially more capable hunting or precision platform without immediately stepping into the cost and weight of a dedicated competition chassis.
