Description
If you've been curious about chassis systems but worried they'd turn your rifle into something unrecognizable, the MDT XRS bridges that gap better than most. It's built around a full-length CNC-machined 6061 aluminum core wrapped in high-strength polymer panels that keep things lighter without sacrificing rigidity. The whole package weighs just under 4 pounds, so it works for both hunting and target work without being a boat to carry around.
What Makes the XRS Stand Out
The real differentiator here is that it doesn't force you to choose between traditional and tactical. You get both grips in the box—a traditional swept grip and a vertical tactical grip—so you can figure out what works for your hand and shooting style. Swapping them takes about 30 seconds with basic tools. The textured polymer panels aren't just there to look good either; they insulate the action from temperature swings and keep your hands in the right place without adding bulk.
Precision Where It Counts
Under the skin is a precision aluminum V-block bedding system that locks your action down tight and consistent. That translates to tighter groups and predictable shooting whether you're on a bench or in the field. The chassis accepts standard AICS magazines and includes an ambidextrous latch, so you're not locked into proprietary hardware. Length of pull adjusts from 13.25 inches up to over 15 inches with the included spacer kit, and the cheek piece dials in quickly for different scope heights or shooting positions.
Built for Modular Thinking
The 12-inch forend comes threaded for M-LOK, so you can hang lights, bipods, or other gear without modification. There's support for ARCA rails too if you're into tripod shooting. Everything about the XRS is designed to grow with your needs. If you want to swap the forend for an enclosed version down the road or add internal weights to dial in balance, MDT makes those pieces and they bolt right in.

Frequently Asked Questions
Does the XRS chassis come with AICS magazines?
No, the chassis accepts standard AICS pattern magazines but none are included in the box. You'll need to source magazines separately depending on your caliber. The ambidextrous magazine latch works with standard aftermarket AICS mags.
Can I switch between the vertical and angled grips easily?
Yes. Both grips are molded and textured, and they swap via four simple screws. Most people can swap them in under a minute, so experimenting with different grip angles is straightforward.
Will the XRS work with a free-floating barrel?
The XRS chassis design supports a free-floating barrel. The precision aluminum V-block bedding system locates your action without touching the barrel, so barrel float remains intact when the action is properly installed.
What makes the XRS different from a full tactical chassis?
The XRS is designed as a crossover between traditional rifle stocks and precision chassis. It keeps the familiar ergonomics and feel of a classic stock shape while giving you the modularity, adjustability, and performance benefits of a modern chassis system. If you want precision features without the pure tactical look and handling, this is the sweet spot.
