MDT ORYX Chassis Custom Cerakote · ARCA Rails · AICS Magazines · Upgrades
A one-piece aluminum chassis with practical adjustability, a free-floating barrel and plenty of room to build. Pair it with our custom Cerakote finishes, a USA-made full-length ARCA rail, AICS magazines and the bipod to match.
Everything You Need. Nothing You Don't.
The ORYX doesn't pretend to be an ACC Elite. It starts with what matters: solid construction, familiar controls and the flexibility to add accessories that actually improve your setup.
A Better Foundation
Rigid aluminum and an action-specific inlet give you a real upgrade from a sporting stock.
Fit the Rifle to You
Adjustable cheekpiece and length of pull for a comfortable, repeatable position behind the optic.
Keep Growing
Leave it simple for hunting, or add rails, panels and weights for more demanding shooting.
Not Your Average ORYX.
Complete ORYX chassis finished in our custom Cerakote patterns, the same patterns as our replacement panel sets. Select the correct rifle inlet before ordering.

ORYX FAQ
Why choose an ORYX instead of an ACC?
The ORYX emphasizes value and an integrated one-piece chassis. The ACC line adds competition-oriented adjustment, balance tuning and an expanded feature set.
What magazines does the ORYX use?
Centerfire ORYX inlets accept AICS-pattern detachable magazines, including MDT and Magpul PMAG AC. Rimfire inlets such as the CZ 457 use the rifle's own magazines. Check the listing for your configuration.
Can I get a custom Cerakote ORYX?
Yes. We offer complete ORYX chassis and replacement panel sets in our custom Cerakote patterns, and custom finishes on the other chassis we carry.
Does the ORYX have QD sling mounts?
Our ORYX rear buttstock weight adds ambidextrous QD cups, and our full-length ORYX ARCA rail adds dual QD sling cups up front.
Will an ORYX fit my rifle?
Fitment depends on manufacturer, action family, action length and inlet. Verify the exact listing before purchasing.
When will the ORYX folding kit launch?
No date yet. Join the Pete's Pillars email list above for the launch announcement.
