PETE'S PILLARS | MADE IN USA | MDT ORYX UPGRADES
Keep Your Sling. Keep Your M-LOK Slot.
The Pete's Pillars MDT Oryx Rear Buttstock Weight gives you two integrated QD sling cups—one on each side—so you can attach your sling without occupying the bottom M-LOK slot. Keep that slot open for a bag rider or rear support accessory, whether you're carrying your rifle through the woods or moving between positions at a match. Made in USA.
A sling shouldn't force you to give up another accessory. On the MDT Oryx, the bottom rear M-LOK slot is valuable space for a bag rider or other support equipment. Our machined aluminum replacement moves sling attachment to the sides of the stock, letting you use your sling and your rear M-LOK accessory together. It's a clean, practical upgrade for both hunters and competition shooters.
Sling Mounts on Both Sides. Bottom Slot Wide Open.
With a QD sling cup on the left and right, you can set up the Oryx for the sling position you prefer. Attach your sling for the walk to your stand, through the field, or between competition stages while leaving the bottom M-LOK position ready for a rear bag rider. No extra QD mount taking up that slot. No need to choose between carrying your rifle and using your preferred rear support.
Add Our Full-Length ARCA Rail. Run a Bipod and a Sling.
Pair the rear weight with our Pete's Pillars Full-Length ARCA Rail for MDT Oryx to get more out of your chassis from front to back. The rail provides a continuous ARCA surface for positioning a compatible bipod or tripod clamp, plus integrated QD sling mounting points. Run your bipod and sling together instead of sacrificing one mounting position for the other. That's a particularly useful combination for a hunting rifle that also sees the bench—or a competition rifle you carry between stages.
An Extra 5.4 Ounces Where a Front-Heavy Rifle Needs It.
There's another advantage built into this replacement: balance. The original Oryx polymer rear part weighs about 1.9 oz; our machined aluminum version weighs approximately 7.3 oz. That's 5.4 oz of additional rear weight to help offset a heavy barrel, suppressor, large optic, or forend-mounted accessories. You get useful rear mass without bolting an awkward weight onto the outside of your stock.
For more control over the front of the rifle, add our solid M-LOK exterior weights at 12.3 oz per pair or the pocketed M-LOK weight set at 11.5 oz per pair. Genuine MDT Oryx M-LOK Side Panels provide additional mounting positions. For a premium ARCA-compatible support setup, take a look at the MDT Ckye-Pod Gen3 Compact.

Frequently Asked Questions
Sling mounting, open M-LOK space, ARCA bipods, weight, and MDT Oryx compatibility.
Why add this rear weight to my Oryx?
For the two integrated QD sling cups first. They let you attach your sling without taking up the bottom M-LOK slot, so you can keep a bag rider or other rear accessory installed. You also gain about 5.4 oz of rear weight to help balance a front-heavy rifle.
Can I use a sling and a rear bag rider at the same time?
Yes. The sling attaches to a QD cup on either side of the replacement weight, while the bottom M-LOK slot stays available for your rear bag rider or compatible support accessory. That is the big advantage of this upgrade.
Can I run a bipod and a sling with your full-length ARCA rail?
Absolutely. Our Full-Length Oryx ARCA Rail gives you an ARCA mounting surface for a compatible bipod plus integrated QD sling cups. Pair it with this rear weight for convenient sling placement at both ends of the rifle. A great setup for hunting, PRS, and NRL22.
Will this fit my MDT Oryx chassis?
Yes. It is made to replace the rear polymer component on the MDT Oryx chassis, whether your Oryx is built around a rimfire or centerfire action. It keeps the factory-style rear arrangement while adding useful sling mounting and weight.
How much weight does it add?
The Pete's Pillars aluminum replacement weighs approximately 7.3 oz compared with around 1.9 oz for the original polymer piece. That adds about 5.4 oz behind the action to help settle a rifle with a heavy barrel, suppressor, or front accessories.
Does it include the sling swivels?
It includes the two QD sling cups built into the weight. Use your preferred compatible push-button QD swivels and sling; the swivels are sold separately.
Is it made in the USA?
Yes. Made in USA by Pete's Pillars. The replacement is machined from aluminum for the MDT Oryx chassis, giving you dual QD sling mounting and added rear balance in one clean part.
Small Change. Big Impact. Pete's Pillars.
