MDT XRS CZ 455 FDE Chassis – Precision Rimfire, NRL22 & Hunting
The MDT XRS CZ 455 Chassis in Flat Dark Earth (105525-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.
Designed for compatible right-hand CZ 455 rimfire rifles, the XRS provides an excellent foundation for NRL22 competition, precision target shooting, and small-game hunting. Its Flat Dark Earth finish complements the traditional stock profile while giving the rifle 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 CZ 455 owners, this combination is especially appealing. The XRS provides rigid action support, adjustable ergonomics, and modular accessory mounting while preserving the comfortable handling characteristics of a traditional rimfire rifle 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 without sacrificing traditional stock ergonomics.
It's the traditional rifle-stock aesthetic many shooters prefer, with the performance and adaptability of a modern precision chassis underneath.
One CZ 455 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 competition chassis and a conventional hunting stock, the XRS provides a practical foundation for both.
- NRL22 & PRS Rimfire: Rigid aluminum bedding, adjustable ergonomics, and modular weight options provide a versatile foundation for positional precision rimfire competition.
- Small-Game Hunting: Traditional stock geometry, textured gripping surfaces, and adjustable fit provide familiar handling for field use.
- Precision Target Shooting: Adjustable cheek height and length of pull help establish a comfortable, repeatable shooting position behind precision optics.
- Custom CZ 455 Builds: An adaptable foundation for compatible CZ 455 American, Varmint, Precision Trainer, and other supported right-hand configurations.
For shooters who want one capable CZ 455 rather than separate hunting and competition rifles, the XRS offers an excellent balance of traditional handling and modern precision-oriented features.

Customize Your MDT XRS – Forends, Weights & Balance

Complete Your CZ 455 Build with Pete's Pillars Precision Parts
At Pete's Pillars, the CZ rimfire platform has been an important part of our manufacturing experience for years. From the CZ 455 through the CZ 457, we've developed and supplied precision rifle components for shooters who value quality materials, practical engineering, and dependable performance.
Consider these products when completing your MDT XRS CZ 455 build:
- Pete's Pillars CZ 455/457 Match Barrels: Explore our precision rimfire barrel options, including heavy-profile configurations for compatible CZ rifles. Verify the specific barrel model and chambering for your CZ 455 before ordering.
- CZ Factory 10-Round .22 LR Magazine – 12004: A genuine CZ factory-pattern magazine compatible with supported CZ 455 and CZ 457 .22 LR rifles. An excellent addition for practice, competition preparation, and range shooting.
- CZ 455 Optics Mounting Accessories: Explore available scope mounting options for the CZ 455 receiver. Select a rail designed specifically for the CZ 455 rather than assuming a CZ 457 scope base will fit.
Compatibility Note: CZ 455 and CZ 457 actions use different stock and receiver configurations. Although some rimfire components are shared, scope rails, firing pins, and other action-specific parts should not be assumed interchangeable.
Building a Dedicated Precision Rimfire Rifle?
The XRS is particularly attractive for shooters who want a CZ 455 capable of both NRL22 competition and traditional field use. Dedicated competition chassis may offer more specialized balance adjustment and positional-shooting features, but the XRS retains the comfortable handling and familiar appearance that make it an excellent all-around option.
For a CZ 455 owner who values versatility over a single-purpose competition setup, the XRS offers a compelling combination of modern chassis engineering and traditional stock ergonomics.
