Upgrade your Ruger American Long Action into a more capable precision rifle with the MDT Oryx 116677-WHT, finished in our distinctive custom Storm Trooper White Cerakote.
The Oryx is built around a simple idea: give shooters the rigidity, ergonomics, adjustability, and modularity of a modern aluminum chassis without forcing them into the cost, weight, or complexity of a dedicated competition platform.
For long-range shooting, hunting, PRS-style competition, and recreational precision use, the Oryx gives the Ruger American Long Action a solid foundation that can remain simple or be expanded as the rifle and shooter evolve.
Shop the Complete MDT Oryx Chassis Lineup for additional rifle platforms, factory colors, and custom Cerakote finishes.
The Storm Trooper White finish gives the Ruger American Long Action Oryx a clean, high-contrast appearance that stands apart from traditional black and earth-tone rifle builds.
This custom Cerakote finish is applied to the Oryx while retaining the full function of the chassis underneath, including its rigid aluminum construction, adjustable shooter fit, AICS-pattern magazine compatibility, and modular M-LOK mounting.
For shooters who want a Ruger American build that is immediately recognizable without sacrificing the practical advantages of the Oryx platform, the 116677-WHT offers a distinctly different option.
The 116677 brings the same Oryx chassis concept used on the Ruger American Short Action to the Ruger American Long Action.
The action is supported by a rigid aluminum chassis and V-block bedding system while the barrel remains free floated, creating a more consistent foundation than a flexible factory stock.
Adjustable cheek height and length of pull help establish a repeatable position behind the optic, while the chassis gives the rifle a modular platform for magazines, bipods, ARCA rails, weights, sling hardware, and other accessories.
The Oryx gives the Ruger American a rock-solid aluminum foundation designed to improve the connection between the barreled action and shooter.
The V-block bedding system supports the action consistently while the free-floated barrel remains isolated from unwanted stock pressure.
For shooters moving from a factory polymer stock, the result is a rifle that feels more planted and gives the shooter considerably more control over fit and accessory placement.
It delivers the features that matter most without requiring the shooter to immediately invest in a full competition chassis system.
One of the biggest advantages of the Oryx is its add-on design.
Out of the box, the chassis provides the foundation needed for a precision-oriented Ruger American Long Action build. From there, ARCA capability, weights, sling mounting, tool-less adjustments, and additional M-LOK mounting can be added only when those features become useful.
That makes the Oryx equally relevant to a hunter improving a factory rifle, a shooter getting into long-range precision, or an experienced competitor building a practical match setup.
The Ruger American Long Action opens the Oryx platform to longer cartridges commonly used for hunting and long-range shooting.
For shooters building around a long-action Ruger American, the Oryx provides the rigid bedding structure, adjustable ergonomics, detachable-magazine compatibility, and accessory mounting expected from a modern precision rifle.
It gives the Ruger American platform room to grow beyond the limitations of the original factory stock without requiring a custom action or complete rifle replacement.
The Oryx is not limited to one style of shooting.
For PRS-style and positional shooting, the rigid chassis and integrated barricade stop provide a stable interface when working from bags, barricades, props, and other supported positions.
For long-range recreational shooting, the adjustable cheekpiece and length of pull help create a repeatable position behind larger optics while the aluminum chassis provides a stable base for heavier barrels and accessories.
For hunting, the rifle can remain relatively simple with a sling and bipod, allowing the shooter to benefit from the rigid chassis without automatically turning the rifle into a heavy competition setup.
The Oryx includes M-LOK mounting along the underside of the forend, providing a modular interface for bipods, weights, rails, sling hardware, bag riders, and other compatible accessories.
Optional Oryx M-LOK side panels can further expand accessory and exterior weight mounting without requiring the chassis itself to be replaced.
For shooters using tripods, ARCA-compatible bipods, barricade stops, or other support equipment, the Oryx can be upgraded with a full-length ARCA rail.
The Pete's Pillars full-length Oryx ARCA rail runs beneath the forend and adds an extended ARCA interface along with integrated QD sling cups.
This allows the same basic Oryx chassis to grow into a more capable positional or competition platform as the shooter's needs change.
The modular Oryx system also allows the balance of the rifle to be changed as the build evolves.
Exterior M-LOK weights can add mass toward the front of the rifle, while the Pete's Pillars replacement rear aluminum buttstock weight can add mass toward the rear.
Instead of simply making the rifle heavier, weight can be positioned where it helps the rifle settle more naturally.
For competition or positional shooting, this can help the rifle sit more consistently on bags and barricades. For a hunting build, the additional weights can simply be omitted.
The Oryx buttstock allows both cheek height and length of pull to be adjusted around the shooter, optic, and preferred shooting position.
A consistent cheek weld and natural position behind the scope are particularly valuable on a long-range rifle, where small changes in head position can become increasingly noticeable as distance increases.
Optional Oryx cheek-riser wheel knobs can also convert the cheekpiece adjustment into a faster, tool-less setup.
The 116677-WHT Ruger American Long Action uses long-action AICS-pattern magazines, bringing a widely supported detachable-magazine system to the Ruger American LA platform.
Magazine selection should be matched to the specific cartridge being used. Pete's Pillars carries MDT magazines for a range of long-action cartridges and configurations.
The Oryx provides clearance for barrels up to approximately 1.25 inches in diameter, leaving room for many heavier hunting, target, and precision barrel profiles.
The barrel remains free floated throughout the forend to help prevent chassis contact from influencing the barrel as the rifle is supported or loaded into position.
The 116677-WHT is designed for compatible right-hand Ruger American Long Action rifles.
The MDT Oryx delivers the features that matter most—rigidity, shooter fit, V-block bedding, free-floated barrel clearance, detachable magazines, and modular accessory mounting—while allowing the shooter to decide what gets added next.
For Ruger American Long Action owners, that means the factory rifle can become a significantly more capable hunting or precision platform without immediately stepping into a much more expensive dedicated competition chassis.
Pete's Pillars is an authorized MDT dealer with years of experience supplying components for both rimfire and centerfire precision-rifle builds.
We stock not only the Oryx chassis itself, but also ARCA rails, weights, cheekpiece hardware, magazines, bipods, bolt components, and other parts needed to expand a Ruger American build as it develops.
Whether you are upgrading a factory Ruger American for hunting, building a long-range rifle, or putting together a practical competition setup, the Oryx provides a strong foundation without forcing you to overbuild the rifle from day one.
ARCA rail, weights, tool-less cheek riser wheels, magazines, sling hardware, bipods, and other accessories are sold separately unless specifically stated otherwise.
