MDT XRS Ruger American Short Action Chassis – Black | Hunting & Precision Rifle Competition
The MDT XRS Ruger American Short Action Chassis in Black (105345-BLK) 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 traditional stock profile and understated black finish are equally suited to field use and precision rifle shooting.
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.

Complete Your Ruger American Build – AICS Magazines
The MDT XRS Ruger American Short Action features an integrated AICS-pattern detachable magazine interface, making it easy to configure your rifle with compatible precision rifle magazines.
Magazine selection depends on your specific cartridge. AICS-pattern magazines are available for popular short-action chamberings, including .308 Winchester, 6.5 Creedmoor, and other supported cartridges.
Magazine Compatibility: The XRS uses the AICS-pattern magazine interface rather than the original Ruger American factory-stock magazine system. Select magazines appropriate for your rifle's cartridge and feeding requirements. Compatibility with AR-pattern magazines should not be assumed.
Want a Dedicated Competition Chassis? Explore MDT ACC Premier Gen2
The XRS is an exceptional crossover between hunting and competition. But if your Ruger American is becoming a dedicated PRS or precision rifle competition build, the MDT ACC Premier Gen2 Chassis is worth considering.
Available in a Ruger American Short Action configuration, the ACC Premier Gen2 offers a more competition-focused design with integrated ARCA mounting, extensive modular weight adjustment, and ergonomics developed around positional precision rifle shooting.
For a dedicated competition setup, the ACC Premier provides greater specialization. For shooters who want a capable hunting rifle and competitive precision rifle platform in one package, the XRS remains an outstanding all-around choice.
Prefer Traditional Craftsmanship? Discover MDT TIMBR CORE Walnut
If the traditional styling of the XRS is what appeals to you most, the MDT TIMBR CORE takes that appeal even further with genuine walnut craftsmanship.
The MDT TIMBR CORE Walnut Stock – Ruger American SA, 114010-WNT combines natural walnut furniture with an internal aluminum micro-chassis, providing modern action support in a traditionally styled rifle stock.
For shooters who want traditional wood aesthetics with a more hunting-oriented stock profile, the TIMBR CORE is a compelling alternative. At approximately 2.6 lbs without bottom metal, it is also lighter than the XRS.
For a configuration that includes the corresponding CORE bottom metal, consider the MDT TIMBR CORE Ruger American SA Walnut Kit – 116033-WNT.
The TIMBR CORE is a separate rifle-stock system, not a replacement panel set for the XRS.
