MDT XRS CZ 457 Chassis – Black | Precision Rimfire, NRL22 & Hunting
The MDT XRS CZ 457 Chassis in Black (105051-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.
For CZ 457 owners who want one rifle capable of competing in NRL22, shooting precision rimfire matches, and heading into the field for small-game hunting, the XRS offers an outstanding balance of versatility and performance.
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 CZ 457 owners, this combination is especially appealing. The XRS provides the rigid action support, adjustable ergonomics, and modular accessory mounting expected from a precision chassis without abandoning the comfortable handling 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, length of pull, and interchangeable grips allow shooters to personalize their fit while maintaining traditional stock ergonomics.
It's the traditional stock aesthetic many shooters prefer, with the performance and adaptability of a modern precision chassis underneath.
One CZ 457 Chassis for Hunting & Competition
The strength of the MDT XRS is how easily it adapts to different shooting applications. Rather than choosing between a conventional hunting stock and a dedicated competition chassis, shooters can configure the XRS to serve both purposes.
- NRL22 & PRS Rimfire: Rigid aluminum construction, adjustable ergonomics, and modular weight options provide an adaptable platform for positional competition.
- Small-Game Hunting: Traditional stock geometry, textured gripping surfaces, and adjustable fit make the XRS comfortable and practical for field use.
- Precision Target Shooting: Adjustable cheek height and length of pull help establish a comfortable, repeatable shooting position behind precision optics.
- All-Around Rimfire Builds: Keep the rifle streamlined for hunting or add weights, ARCA accessories, and competition equipment as your shooting needs evolve.
For shooters who want one capable CZ 457 rather than separate hunting and competition rifles, the XRS offers an impressive balance of practicality and precision-oriented features.
