Description

The MDT XRS Chassis for the CZ 457 sits in a sweet spot a lot of rimfire shooters have been chasing. It gives you the rigidity, adjustability, and accessory options of a full-blown precision chassis while keeping the shape and handling of a conventional rifle stock. Drop your CZ 457 action in and you get a rifle that shoulders naturally but performs like something built for the firing line.

What Makes the XRS Chassis Tick

The backbone here is a full-length core that is CNC machined from 6061 aircraft-grade aluminum, wrapped in high-strength textured polymer side panels. Those panels do double duty, giving you a secure grip while insulating your hands from cold metal on frosty mornings. The precision aluminum V-block bedding system locks the action in place for consistent, repeatable placement, and the barrel free-floats so shifting weather and humidity stay off your groups. At roughly 3.9 pounds depending on the inlet, it holds a nice balance between a carry-friendly hunting build and a stable target setup.

Dialing In Your Fit With the XRS

Adjustability is where this chassis really earns its keep. Length of pull runs from 13.25 inches out past 15 inches using the included spacers, and the quick-adjust cheek piece lets you set comb height to match your scope's height over bore in seconds. It also ships with two interchangeable grips, one angled and one vertical, so you can pick the hand position and trigger reach that suits your style. Swapping them takes just a couple of screws.

Building It Out

The generous 12-inch forend comes loaded with M-LOK slots for bipods, ARCA rails, Picatinny sections, and whatever else your discipline calls for. For the CZ 457 inlet, MDT sets this chassis up to run factory rimfire magazines, so you can keep using the mags you already own. Whether you're shooting rimfire matches, working on fundamentals, or heading out for small game, the XRS gives you a solid foundation to grow into.

Frequently Asked Questions

Which magazines does the XRS Chassis use on the CZ 457?

For the CZ 457 inlet, MDT builds the XRS to run factory rimfire magazines, so the mags that came with your rifle will work. Just note that the AICS-pattern magazine compatibility you'll see mentioned on the centerfire XRS versions does not apply to this rimfire setup. Keep using your standard CZ 457 mags and you're good to go.

Is installing the CZ 457 into the XRS Chassis a drop-in job?

Pretty much. The inlet is already machined specifically for the CZ 457 action, so it's a straightforward swap with basic tools and the supplied hardware. Most folks have it done in a few minutes without any additional fitting or gunsmithing.

Can I mount a bipod and ARCA rail on the XRS forend?

Yes. The 12-inch forend is loaded with M-LOK slots, so you can attach M-LOK bipods directly or add ARCA and Picatinny rail sections for even more mounting options. That gives you plenty of room to set up bipods, weights, and other accessories for the way you shoot.

Does the XRS Chassis come with interchangeable grips?

It does. MDT includes both an angled grip and a vertical grip in the box, and swapping between them only takes a couple of screws. This lets you fine-tune your hand placement and trigger reach to match whether you prefer a modern AR-style feel or a more traditional rifle grip.
