MDT XRS CZ 457 FDE Chassis – Precision Rimfire, NRL22 & Hunting
The MDT XRS CZ 457 Chassis in Flat Dark Earth (105051-FDE) brings together traditional rifle-stock styling and modern precision chassis engineering. Designed for the CZ 457 rimfire platform, it combines the familiar feel of a conventional rifle stock with the rigidity, adjustability, and modular performance of a full aluminum chassis.
Whether you're building a competitive NRL22 rifle, upgrading your precision .22 LR setup, or configuring a capable small-game hunting rifle, the XRS provides exceptional all-around versatility. Its Flat Dark Earth finish complements the traditional stock profile while giving your CZ 457 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: the freedom to build one rifle that performs well across multiple disciplines.
It preserves the familiar feel, classic proportions, and comfortable handling of a traditional rifle stock while delivering the structural advantages of a modern precision chassis. You can hunt with it, compete with it, and customize it without committing your rifle to one particular purpose.
For CZ 457 owners, this combination is especially appealing. The XRS provides the rigid action support, adjustable ergonomics, and accessory mounting desired for precision rimfire competition while retaining the practical handling characteristics of a conventional hunting rifle.
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 without sacrificing traditional stock ergonomics.
It's the traditional rifle-stock aesthetic many shooters appreciate, with the performance and adaptability of a full 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 dedicated competition chassis and a conventional hunting stock, the XRS offers a practical foundation for both.
- NRL22 & PRS Rimfire: Rigid aluminum bedding, adjustable ergonomics, and modular weight options provide a versatile foundation for positional competition.
- Small-Game Hunting: Traditional stock geometry, textured gripping surfaces, and comfortable ergonomics make the XRS practical for field use.
- Precision Target Shooting: Adjustable cheek height and length of pull help establish a comfortable, repeatable position behind precision optics.
- All-Around CZ 457 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 CZ 457 rather than separate hunting and competition rifles, the XRS delivers an excellent balance of traditional handling and precision-oriented functionality.
