Description
Some folks love the shootability of a full chassis but can't get comfortable with the boxy, competition-gun feel. The MDT XRS was built for exactly that crowd. It keeps the familiar profile and hand position of a traditional rifle stock while packing in the features that make a chassis worth having: a rigid aluminum backbone, adjustable ergonomics, detachable magazines, and a free-floating barrel. For a Remington 700 short action right-hand rifle, it's one of the cleanest ways to modernize a factory gun without losing the feel you already like.
What Makes the XRS Chassis Tick
The heart of the XRS is a full-length CNC-machined 6061 aircraft-grade aluminum core wrapped in high-strength textured polymer panels. Those panels insulate your hands from cold metal in the field and give the chassis a grippy, comfortable surface. The aluminum V-block bedding system locks your barreled action in for a repeatable, accurate fit with no bedding compound or gunsmithing wizardry required. It accepts barrels up to about 1.25 inches at the free-floated forend, so heavier profiles have room to breathe.
Dialing In the Fit
Length of pull adjusts through included spacers from roughly 13 inches out past 15, and the quick-adjust cheek piece raises the comb up to about 1.5 inches to line your eye up behind higher-mounted optics. The chassis ships with two interchangeable overmolded grips, one angled and one vertical, so you can set your hand and trigger reach where it feels natural. AICS-pattern magazines feed reliably through an ambidextrous latch that's easy to work from either side.
Built to Grow With You
The generous 12-inch forend is loaded with M-LOK slots at the 3, 6, and 9 o'clock positions, ready for a bipod, ARCA rail, or Picatinny section. There's an integrated barricade stop, sling swivel studs front and rear, and a whole catalog of MDT add-on weights and enclosed forends if you want to build it out for PRS-style shooting. Installation is genuinely simple: pull two action screws, drop the barreled action in, torque it down, and you're ready to go. Weighing in around 3.9 pounds depending on inlet, it hits a sweet spot for both backcountry hunting and target work.

Frequently Asked Questions
Is the MDT XRS chassis a true drop-in for a Remington 700 short action?
Yes. For a factory Remington 700 short action right-hand barreled action, you remove the two action screws, drop the barreled action into the XRS, and torque the screws back down to spec. No bedding, no gunsmithing, and the action screws are captured so you won't lose them. Compatible Rem 700-footprint clones drop in the same way.
What magazines does the XRS chassis take?
It runs standard AICS-pattern short action magazines, including common .223-family and .308-family options, released through an ambidextrous latch that's easy to reach from either side. Reviewers have run AICS metal mags and MDT polymer mags without issues. If your particular action needs more or less mag clearance, MDT offers latches in different lengths to sort out the fit.
Can I free-float a heavier or bull-profile barrel in the XRS?
You can. The forend is free-floating and clears barrels up to roughly 1.25 inches in diameter, which covers most sporter, varmint, and many heavy profiles. If you're running a very thick straight-taper barrel, it's worth measuring first to confirm clearance.
Is the MDT XRS better suited to hunting or precision matches?
It's a crossover, which is the whole point. At around 3.9 pounds it carries well for hunting while still giving you an adjustable comb, length of pull, and M-LOK real estate for a bipod. For heavier-recoiling PRS use, many shooters add MDT's forend and buttstock weights to settle it down and better spot their own hits.
