Description
The MDT ORYX Sportsman Chassis takes a factory Remington 700 Long Action and turns it into a rifle that feels like it belongs on a barricade or a bipod instead of a gun store rack. This version is set up for right-handed shooters and finished in Flat Dark Earth, a color that blends in well with most optics and accessory setups. Instead of dropping your barreled action into wood or polymer, you're bolting it into a solid piece of aluminum that was designed from the ground up to help your factory rifle shoot tighter groups.
What Makes the ORYX Sportsman Chassis Feel Different
The chassis is machined from aircraft grade 6061 aluminum and finished with a MIL-Spec Type III hard anodized coating, so it holds up to years of use in the truck, the field, or on the line. Your action gets bedded on an aluminum block for a rigid, repeatable foundation, and the barrel channel is free floated the entire length of the forend. That combination is what actually tightens up groups compared to a stock factory setup, since you're removing the flex and inconsistency that comes with a traditional stock.
Fitting the ORYX Sportsman Chassis to You
Length of pull adjusts from roughly 13 to 13.5 inches right out of the box, and MDT's spacer kit lets you stretch that out even further if you need a longer stock for a bigger frame. The cheekpiece adjusts too, so getting behind a scope or a red dot lines up your eye correctly instead of forcing you to crane your neck. It runs AR15 pattern pistol grips, so you can swap in whatever grip angle feels best in your hand, and the forend includes M-LOK slots along with an ARCA rail interface for bipods and tripod work.
On the feeding side, this chassis is built around AICS pattern magazines, giving your Remington 700 detachable box mag capability it didn't have from the factory. It also plays nice with clone actions from makers like Defiance and Terminus if you ever upgrade down the road. Whether you're chasing coyotes at first light, working through a PRS stage, or just want a more stable platform for punching paper at distance, this chassis gives a factory rifle a serious upgrade without the cost of a full custom build.

Frequently Asked Questions
Will the ORYX Sportsman Chassis fit my Remington 700 Long Action barreled action?
Yes, this chassis is inlet specifically for the Remington 700 Long Action footprint, so your factory barreled action drops right in. It also fits several clone actions from makers like Defiance and Terminus, so it's a solid option even if you upgrade your action later on.
What magazines work with the ORYX Sportsman Chassis?
This chassis is built around AICS-pattern magazines in the 3.715 inch long action length. Keep in mind the magazine itself is not included with the chassis, so you'll want to pick one up separately if you don't already have one.
Can I adjust the fit of the ORYX Sportsman Chassis for my body size?
Definitely. Length of pull adjusts in the 13 to 13.5 inch range out of the box, and MDT sells a spacer kit if you need more length than that. The cheekpiece also adjusts up and down so you can get proper eye alignment with your scope or optic.
Is this chassis only for competition shooting?
Not at all. While the ORYX Sportsman Chassis has a strong track record in PRS and NRL Hunter matches, plenty of hunters run it for coyote, hog, and whitetail hunting thanks to the ARCA rail and M-LOK forend for mounting bipods or tripod adapters. It's a versatile chassis that works just as well in a blind as it does on a competition stage.
