PETE'S PILLARS | USA-MADE ORYX CHASSIS UPGRADES
Keep the Oryx. Gain the Rail.
Your MDT Oryx deserves the same ARCA versatility found on dedicated competition chassis. The Pete's Pillars Full-Length ARCA Rail brings a continuous support-mounting surface, three integrated QD sling cups, and precision-machined billet aluminum construction to the Oryx forend. Made in the USA and ready to take your rifle further.
Good positioning makes a difference. Whether you're sliding a bipod forward for prone shooting, drawing it back for a barricade, or securing your rifle to a tripod, a full-length ARCA rail gives you room to work. Our MDT Oryx Full-Length ARCA Rail brings that flexibility to the chassis you already own, with the sling-mounting features to match.
A Full-Length Advantage for Your Oryx
Instead of working around a short rail section, you get a continuous ARCA interface beneath the Oryx forend. Move compatible bipods, tripod clamps, and other ARCA accessories along the rail to suit the stage, shooting position, terrain, or balance of your rifle. From NRL22 and PRS to centerfire precision and field shooting, it's a practical upgrade you'll appreciate every time you change positions.
For shooters comparing the MDT 104595 factory Oryx ARCA rail, Pete's Pillars offers its own purpose-built solution with three integrated QD sling cups and custom-machined M-LOK mounting hardware. You're getting more than a mounting track: you're adding meaningful sling flexibility to a platform that's already earned its place on the firing line.
Three QD Sling Cups. One Less Compromise.
Adding a full-length rail shouldn't mean giving up convenient sling attachment. We've integrated three QD sling cups directly into the ARCA rail so you can configure your sling without using a separate rail-mounted QD adapter. That leaves more of the ARCA surface available for your shooting supports while keeping the Oryx ready for competition and the field.
Billet Aluminum. Hardcoat Finish. Mounting Hardware Included.
We machine this rail from billet aluminum and finish it in black hardcoat anodizing for a durable, clean-looking match with the Oryx chassis. The kit includes the mounting hardware, including our machined M-LOK nuts, so the rail and its attachment components are designed to work together from the start. These are the details that matter when you're building a rifle around dependable equipment.
Finish Building Your Oryx
We manufacture more than the rail. Match it with our Pete's Pillars Oryx Rear Buttstock Weight to tune rear balance and gain additional ambidextrous QD sling attachment points. For shooters adding mass up front, our solid M-LOK exterior weights add 12.3 ounces per pair, while the pocketed version adds 11.5 ounces per pair.
Need more places to mount those weights? Genuine MDT Oryx M-LOK Side Panels add mounting positions along the sides of the forend. Put the ARCA rail to work with an MDT Ckye-Pod Gen3 Compact, a premium ARCA-capable bipod made for demanding precision rifle shooting. Pete's Pillars makes the Oryx upgrades and supplies the complementary MDT gear to build a complete setup.

Frequently Asked Questions
Oryx compatibility, ARCA accessories, QD sling cups, mounting hardware, and building out your chassis.
Will this rail fit my MDT Oryx chassis?
Yes. This rail is made for the standard MDT Oryx Sportsman forend, including Oryx rimfire and centerfire chassis builds. It's an Oryx-specific upgrade, with the fit and full-length profile designed around that chassis.
Why choose a full-length ARCA rail instead of a short section?
More room to position your support equipment. A full-length rail lets you slide a compatible bipod or tripod clamp forward or back for prone, barricades, field positions, or your preferred balance point. It's one of the most useful upgrades you can make to an Oryx used for positional shooting.
How many QD sling cups does this rail have?
Three integrated QD sling cups. They're built into the rail, so you have sling attachment options without adding another adapter to the ARCA surface. Use your compatible QD sling swivels; swivels are not included with the rail.
Does it come with the hardware to mount it?
Yes. The kit comes with the mounting hardware, including Pete's Pillars machined M-LOK nuts. The billet aluminum rail and its attachment hardware are designed as one complete Oryx upgrade.
Will my ARCA bipod or tripod clamp work with it?
Yes, the rail provides a full-length ARCA interface for compatible bipod and tripod clamps. You can position the support where it works best for the rifle and shooting position. The MDT Ckye-Pod Gen3 Compact with its ARCA-capable head is one excellent pairing.
Can I use this rail with Oryx M-LOK side panels and exterior weights?
Absolutely. The ARCA rail runs beneath the forend, while compatible M-LOK side panels give you mounting positions along its sides. Add our solid or pocketed Pete's Pillars exterior weights to tune front-end balance and make the Oryx your own.
How does it compare with the MDT 104595 Oryx ARCA rail?
Both bring full-length ARCA mounting to the Oryx. The Pete's Pillars design combines that mounting flexibility with three integrated QD sling cups, billet aluminum construction, and our machined M-LOK mounting hardware. It's a premium USA-made option for shooters who want more from their existing Oryx.
Small Change. Big Impact. Pete's Pillars.
