MDT XRS Ruger American Short Action Chassis – FDE | Hunting & Precision Rifle Competition
The MDT XRS Ruger American Short Action Chassis in Flat Dark Earth (105345-FDE) combines the familiar styling and comfortable ergonomics of a traditional rifle stock with the rigidity, adjustability, and modular performance of a modern precision rifle chassis.
Whether you're upgrading a Ruger American hunting rifle, building a precision target rifle, or preparing for PRS-style competition, the XRS provides an exceptionally versatile foundation. Its Flat Dark Earth finish complements the traditional stock profile while offering a distinctive, field-ready appearance.
Why We Recommend the MDT XRS
At Pete's Pillars, we believe the MDT XRS is one of the most underrated chassis systems MDT makes. While dedicated competition chassis often receive the most attention, the XRS offers something arguably more valuable to many rifle owners: versatility.
It retains the familiar feel and traditional appearance of a conventional rifle stock while delivering the structural advantages of a full aluminum chassis. You can hunt with it, compete with it, and customize it without committing your rifle to one particular discipline.
For Ruger American owners, that combination is especially appealing. The XRS provides rigid action support, adjustable ergonomics, and modular accessory mounting while retaining the practical handling characteristics of a traditional hunting stock.
Beneath its textured polymer exterior is a full-length CNC-machined 6061 aluminum core with precision V-block bedding. Adjustable cheek height, spacer-adjustable length of pull, and interchangeable grips allow shooters to personalize their fit while maintaining familiar stock ergonomics.
It's the traditional rifle-stock aesthetic many shooters prefer, with the performance and adaptability of a modern precision chassis underneath.
One Ruger American Chassis for Hunting & Competition
The greatest strength of the MDT XRS is how easily it adapts to different shooting applications. Rather than choosing between a dedicated hunting stock and competition chassis, shooters can configure the XRS for both purposes.
- Hunting: Traditional stock geometry, textured gripping surfaces, and adjustable ergonomics provide a practical foundation for field rifles.
- PRS & Precision Rifle Competition: Rigid aluminum bedding, optional chassis weights, and accessory mounting options support positional shooting and rifle balance customization.
- Long-Range Target Shooting: Adjustable cheek height and length of pull help establish a comfortable, repeatable shooting position behind precision optics.
- All-Around Ruger American Builds: Keep the rifle streamlined for hunting or add weights, ARCA accessories, and competition equipment as your needs evolve.
For shooters who want one capable rifle rather than separate hunting and competition setups, the XRS delivers an excellent balance of practicality and precision-oriented features.

Customize Your MDT XRS – Forends, Weights & Balance
One of the greatest advantages of the XRS is its ability to evolve with your shooting. Keep the chassis streamlined for hunting, or add strategically positioned weights and mounting accessories for precision rifle competition.
- MDT XRS Enclosed Forend – 105277-BLK: Replace the standard forend with an enclosed aluminum design featuring an integrated full-length ARCA/RRS dovetail and additional M-LOK mounting positions. An excellent upgrade for competition bipods, tripod interfaces, and positional shooting accessories.

- MDT XRS Buttstock LOP Spacer Weight – 105330-BLK: Add approximately 0.8 lb of rearward weight while increasing length of pull by 0.5". A practical option for balancing heavier barrels, optics, and forward-mounted accessories.
- Pete's Pillars M-LOK Mini Weights – PPWM: Our American-made steel mini weights provide 6 oz per pair of compact exterior weight adjustment. Case-hardened and black nitrided, they offer a practical way to fine-tune chassis balance without oversized exterior weights.
Complete Your Ruger American Build – AICS Magazines
The MDT XRS Ruger American Short Action features an integrated AICS-pattern detachable magazine interface. Pair your chassis with a magazine appropriate for your specific cartridge and shooting application.
For shooters building around popular short-action chamberings such as .308 Winchester and 6.5 Creedmoor, MDT offers several compatible AICS-pattern magazine options.
- MDT Polymer AICS 10-Round Magazine – FDE, 104447-FDE: A Flat Dark Earth magazine for compatible .308 Winchester and 6.5 Creedmoor-family cartridges. A natural color match for your FDE XRS chassis.
- MDT AICS Poly/Metal Hybrid 10-Round Magazine – 103089-BLK: Combines polymer and metal construction for supported short-action cartridges. A practical choice for precision rifle competition and range shooting.
- Magpul AICS 5-Round Short Action Magazine – MAG549-BLK: A lower-capacity magazine option for compatible .308-family cartridges, especially useful for hunting configurations.
Magazine Compatibility: The XRS uses an AICS-pattern magazine interface rather than the original Ruger American factory-stock magazine system. Magazine selection depends on cartridge dimensions and receiver configuration. Compatibility with AR-pattern magazines should not be assumed.
Want a Dedicated Competition Chassis? Explore MDT ACC Premier Gen2
The XRS is an outstanding crossover between hunting and competition. For Ruger American owners building a dedicated PRS or precision rifle competition setup, MDT offers a more specialized alternative.
The MDT ACC Premier Gen2 Chassis – Ruger American SA provides a competition-oriented platform with integrated ARCA mounting, a longer forend, modular weight adjustment, and ergonomics designed around positional shooting.
For a dedicated competition rifle, the ACC Premier Gen2 offers additional specialization. But for shooters who want one rifle capable of hunting, target shooting, and competing, the XRS remains one of MDT's most versatile chassis systems.
Prefer Traditional Craftsmanship? Discover MDT TIMBR CORE Walnut
If the traditional aesthetics of the XRS are what appeal to you most, the MDT TIMBR CORE offers an alternative that takes traditional craftsmanship even further.
The MDT TIMBR CORE Walnut Rifle Stock – Ruger American SA, 114010-WNT combines genuine walnut construction with an internal aluminum micro-chassis, offering the warmth and character of a traditional wood stock with modern precision bedding technology.
For shooters who appreciate natural walnut, classic stock proportions, and traditional rifle craftsmanship, the TIMBR CORE is an appealing alternative. At approximately 2.6 lbs without bottom metal, it is also lighter than the XRS.
For a more complete configuration, consider the MDT TIMBR CORE Ruger American SA Walnut Kit – 116033-WNT, which includes the corresponding CORE bottom metal.
The TIMBR CORE is a separate stock system rather than a replacement panel kit for the XRS. Confirm rifle generation and action compatibility before ordering.
