Description
The MDT XRS is the chassis for the person who likes the feel of a traditional rifle stock but wants the guts of a modern precision platform underneath it. Built around a full-length CNC-machined 6061 aluminum core wrapped in high-strength textured polymer panels, it drops your Remington 700 short action barreled action into a rigid, repeatable foundation without any bedding compound or gunsmithing. The polymer skins keep the chassis from getting freezing cold or blistering hot in your hands, which matters when you're sitting on a mountainside in November or grinding through a match in July. At roughly 3.9 pounds depending on the inlet, it lands in a sweet spot between a hunting rig and a target gun.
Building Around the XRS Chassis
The aluminum V-block bedding system does the heavy lifting on accuracy. Your action torques directly to the metal spine, so barrel harmonics stay consistent shot to shot and the barrel free-floats out to a fat 1.25-inch diameter. That means you can run a heavy varmint or match profile without touching the forend. Installation is about as simple as it gets: pull your two action screws, drop the barreled action in, torque it down, and you're done. Most folks knock it out at the bench in under an hour with a hex key and a torque wrench.
Dialing In the XRS Fit
This is where the XRS earns its keep. Length of pull adjusts from around 13.25 inches out past 15 with the included spacers, and the quick-adjust cheekpiece gives you up to 1.5 inches of comb rise to get your eye lined up behind a tall scope. The chassis ships with both an angled grip and a vertical grip, so you can set your hand and trigger reach the way you like it. Feeding comes from standard AICS-pattern magazines through an easy ambidextrous latch, and the 12-inch forend carries M-LOK slots on multiple faces for bipods, ARCA rails, sling hardware, and weights. Whether it becomes a hunting rifle, a range toy, or a match gun is entirely up to how you spec it out.

Frequently Asked Questions
What magazines does the MDT XRS chassis use?
The XRS feeds from standard AICS-pattern short-action magazines through an ambidextrous latch, so you have plenty of options from metal AICS mags to MDT's own polymer mags. A true short-action AICS magazine is the safe bet for reliable feeding. Some polymer AICS mags can fit tight depending on your specific action, and if you ever run into clearance issues MDT will send out a different-length mag latch to sort it out.
Will the MDT XRS fit a heavy or bull barrel?
Yes. The forend free-floats and clears barrels up to 1.25 inches in diameter, which covers most heavy varmint and match profiles. Your barrel won't touch the chassis, so harmonics stay consistent for tighter groups.
How hard is it to install the XRS chassis on a Remington 700?
It's about as simple as a chassis swap gets and needs no gunsmithing. You remove the two action screws from your factory stock, drop the barreled action into the XRS, and torque the provided screws to spec. Most people finish the job in under an hour with a hex key and a torque wrench.
Is the XRS a good fit for both hunting and target shooting?
That's exactly what it was designed for. At roughly 3.9 pounds it's light enough to carry into the field but rigid and adjustable enough for the range or a match. The interchangeable grips, adjustable comb, and M-LOK forend let you configure it as a lightweight hunter or a loaded-up precision rig.
