Description
Take a factory Remington 700 long action and turn it into a legitimate long-range platform without breaking the bank. The MDT Oryx Sportsman is machined from a single piece of 6061-T6 aircraft-grade aluminum, finished in a Mil-Spec Type 3 hard anodized gray, so you get a rock-solid spine running from the forend to the buttpad. The action beds down on a V-block, the barrel free floats, and the whole thing bolts up with two screws. If you can run a screwdriver and torque wrench, you can install this at the kitchen table in about ten minutes.
What the Oryx Sportsman Does for Your 700
The biggest upgrade most folks notice right away is the feel. Settle in behind the scope and there's a more direct connection between you and the rifle, thanks to that stiff aluminum core cutting out the flex you get from a factory tupperware stock. You also pick up removable AICS-pattern magazines, which is a huge step up from fumbling with an internal box. Long action models run the 3.715-inch AICS mags, so you can top off fast and carry the right amount of ammo for the day.
Dialing In the Fit
The integrated buttstock is fully adjustable, with a length of pull that runs 13 to 13.5 inches out of the box and room to add more with MDT's spacer kit. The cheek riser adjusts too, so you can get your eye lined up behind the optic the same way every single time. It accepts standard AR-15 grips, so if you've got a favorite pistol grip already, swap it right in. The full-length M-LOK forend gives you plenty of real estate for a bipod, sling, or ARCA rail when you want to run a tripod.
This chassis has earned its reputation in the field and on the clock, showing up in NRL Hunter, PRS, and rimfire matches. Whether you're stretching your hunting rig out past where you're comfortable now or getting your feet wet in precision matches, the Oryx Sportsman is a lot of chassis for the money.

Frequently Asked Questions
Will the Oryx Sportsman fit my Remington 700 long action?
Yes, this model is cut specifically for the Remington 700 long action in a right-hand configuration. It also works with popular 700 clone actions from makers like Defiance and Terminus, which is handy if you plan to build off this platform down the road. Just double check your action is a right-hand long action before you order.
What magazines does the Oryx Sportsman chassis use?
It runs AICS-pattern magazines, and the long action version uses the 3.715-inch length mags. That means you get removable box magazine capability even if your factory rifle came with an internal box. MDT and other brands make AICS mags in various capacities and calibers to match your setup.
How hard is it to install the Oryx chassis?
It's about as easy as chassis swaps get. Pull your barreled action out of the factory stock, drop it into the Oryx, and snug down the two action screws that come included. Most folks have it done in ten to fifteen minutes with no gunsmithing required.
Can I adjust the length of pull and cheek height?
Absolutely. The buttstock comes with an adjustable length of pull from 13 to 13.5 inches and an adjustable cheek riser so you can line up behind your optic consistently. If you need more length of pull, MDT offers a spacer kit that adds up to about an inch total.
