MDT XRS Chassis System – CZ 457 – Black
The MDT XRS Chassis System for CZ 457 combines the familiar fit and feel of a traditional rifle stock with the performance and adjustability of a modern precision rifle chassis. Designed as a versatile performance upgrade, the XRS provides a solid platform for both hunting and target applications while retaining a traditional stock-style profile.
Each XRS Chassis is built around a full-length CNC-machined 6061 aircraft-grade aluminum core with high-strength textured polymer side panels. The aluminum core provides a rigid foundation, while the polymer panels help insulate the chassis from changing environmental conditions.
Precision V-Block Bedding
The MDT XRS uses a precision aluminum V-block bedding system designed to provide a secure fit between the chassis and rifle action. This rigid bedding platform helps maximize the performance and accuracy potential of the rifle.
The chassis also provides a free-floating barrel configuration, helping maintain consistent barrel clearance.
Traditional Stock Feel with Chassis Performance
The XRS Chassis is designed for shooters who prefer the familiar ergonomics of a traditional rifle stock but want the advantages of a modern chassis system.
Its configuration combines traditional stock-style handling with features such as:
- Adjustable length of pull
- Quick-adjust cheek piece
- Interchangeable grips
- M-LOK accessory mounting
- AICS-pattern magazine compatibility
- Ambidextrous magazine latch
- V-block bedding
- Free-floating barrel
This makes the MDT XRS Chassis System CZ 457 a versatile option for upgrading a factory rifle or building a customized precision rifle platform.
Adjustable Ergonomics
The XRS features an adjustable length of pull using spacers, allowing adjustment from 13.25″ to 15+”. This makes it easier to tailor the stock dimensions to the shooter’s preferred fit.
A quick-adjust cheek piece allows the cheek position to be adjusted for the height of the optic above the bore.
The XRS also includes interchangeable angled and vertical grips. These grips can be swapped to customize hand placement and help achieve a comfortable and consistent trigger interface.
M-LOK Forend
The XRS features a generous 12″ forend with integrated M-LOK slots. These mounting points provide flexibility for attaching compatible accessories and mounting solutions.
The forend also supports the attachment of ARCA or Picatinny rails, making the chassis suitable for a variety of shooting setups.
AICS Magazine Compatibility
The MDT XRS Chassis accepts standard AICS-pattern magazines and features an easy-to-manipulate ambidextrous magazine latch.
This provides straightforward magazine operation while giving the chassis broad compatibility with standard AICS-pattern magazine systems.
Durable Polymer Construction
High-strength textured polymer side panels surround the aluminum chassis core. The panels provide a comfortable gripping surface while helping insulate the shooter’s hands from temperature changes.
This construction helps maintain comfortable handling across changing outdoor conditions.
