Description
The MDT XRS Chassis is what happens when a company that lives in the precision rifle world decides to build something that still feels like a hunting rifle in your hands. Instead of the boxy vertical-grip look most chassis systems go for, the XRS keeps a familiar buttstock shape and swept grip, so it shoulders naturally whether you're glassing a ridgeline or settled behind a bag on the line. This version drops right into a Tikka T3 short action, right-hand, and comes finished in a matte Flat Dark Earth that looks sharp and hides handling wear.
What Makes the XRS Chassis Different
Underneath the polymer skins is a full-length CNC-machined 6061 aluminum backbone that runs from the forend through the grip and into the buttstock. That rigid core is the reason it doesn't creak, flex, or feel spongy under recoil the way plenty of plastic stocks do. The precision aluminum V-block bedding gives your action a repeatable, stress-free home so you can torque your action screws down and trust your zero. MDT even includes captured action screws so you're not chasing hardware around the bench during install.
Dialing In the XRS to Fit You
Fit is where this chassis earns its keep. Length of pull adjusts with stacking spacers from roughly 13.25 inches out past 15, and the quick-adjust cheek piece lets you set scope height over bore without tools, which matters a lot if you run tall rings or a big objective. It ships with both a swept and a vertical pistol grip so you can try each and settle on what your hand likes, and swapping them takes four screws and about a minute.
The 12-inch flat-bottom forend carries M-LOK slots at the 3, 6, and 9 o'clock positions, so bipods, ARCA rails, and Picatinny sections all bolt right on. The magwell runs standard AICS pattern magazines with an ambidextrous latch, which keeps you in cheap, easy-to-find mags instead of anything proprietary. At about 3.9 pounds depending on inlet, it stays light enough to hunt with while giving you the adjustability a range or match rifle wants.

Frequently Asked Questions
Will the MDT XRS Chassis fit my Tikka T3 or T3x?
This chassis is cut for the Tikka T3 short action in a right-hand configuration, and the Tikka T3 and T3x share the same action footprint, so it works with both. Drop-in is straightforward since MDT includes captured action screws. As always, confirm your rifle is a short action and right-hand before ordering.
What magazines does the XRS Chassis use?
The XRS runs standard AICS pattern magazines through a magwell with an ambidextrous latch. That is a big plus because AICS mags are widely available and affordable rather than proprietary. You are free to pick capacities and brands that suit your caliber and use.
Can I mount a bipod and ARCA rail on the XRS?
Yes. The 12-inch flat-bottom forend has M-LOK slots at the 3, 6, and 9 o'clock positions, so you can bolt on a bipod, an ARCA rail, or Picatinny sections depending on your setup. For full-length ARCA coverage, MDT also offers a dedicated XRS Enclosed Forend as an upgrade.
Is the XRS light enough to hunt with, or is it just a range chassis?
It comes in around 3.9 pounds depending on inlet, which keeps it reasonable for carrying in the field while still giving you the adjustability a precision rig wants. The traditional stock shape and swept grip make it feel natural when shouldering on game. It genuinely bridges hunting and target use, which is the whole point of the crossover design.
