The MDT XRS takes your CZ 457 action and drops it into a modern chassis that still looks and handles like a traditional rifle stock. That middle-ground feel is the whole point here. You get the rigidity, adjustability, and accessory options of a precision chassis, but the ergonomics stay familiar enough that it never feels like you're wrestling a competition-only race gun. It's a genuine crossover, and that's exactly why so many CZ 457 owners land on it.
Underneath the textured polymer panels sits a full-length CNC-machined 6061 aircraft-grade aluminum core. That aluminum backbone is what gives the rifle its consistency, and the precision V-block bedding system locks your action in tight for repeatable shot placement. The polymer side panels aren't just for looks either. They insulate your hands from cold steel on frosty mornings and stay comfortable when the temperature climbs, so your grip stays consistent no matter the conditions.
Fit is where this chassis earns its keep. Length of pull adjusts from 13.25 inches out past 15 inches using the included spacers, and the quick-adjust cheek piece gives you roughly 1.5 inches of vertical travel to match your cheek weld to your scope height. The chassis ships with both an angled grip and a vertical grip, and swapping between them is a quick job that lets you set up your hand placement and trigger reach the way you like it. The ambidextrous magazine release works cleanly from either side.
The generous 12-inch forend comes loaded with M-LOK slots across its faces, so mounting an ARCA rail, a picatinny section, a bipod, or a barricade stop is straightforward. There's a built-in barricade stop and a wide, flat forend bottom that adds real stability off bags and obstacles. At around 3.9 pounds depending on inlet, it keeps things manageable whether you're building a rimfire trainer, a target rig, or a capable hunting setup. This variant is cut specifically for the CZ 457 and runs factory CZ 457 rimfire magazines.
This chassis is machined specifically for the CZ 457 action, so it's a drop-in swap for most owners using standard tools. You retain your rifle's original magazine release lever, and MDT includes the correct hardware to complete the install. If you're not comfortable working on your own action, having a gunsmith handle it is never a bad idea.
The CZ 457 version of the XRS is designed to run factory CZ 457 rimfire magazines. This is an important distinction, since the centerfire XRS models use AICS-pattern magazines instead. Stick with your standard CZ 457 mags and you're good to go, and the ambidextrous mag latch releases smoothly from either side.
Yes, both are adjustable. Length of pull runs from 13.25 inches out past 15 inches using the included spacer kit, and the quick-adjust cheek piece gives you about 1.5 inches of vertical travel to line up your cheek weld with your optic. That range covers most body sizes and shooting positions comfortably.
The 12-inch forend has M-LOK slots built into its faces, so you can attach ARCA rails, picatinny sections, bipods, barricade stops, and other accessories. It also has an integrated barricade stop and a wide, flat bottom for shooting off bags and obstacles. That makes it easy to configure the rifle for competition, hunting, or general range work.
