Oryx Chassis Review – rifleshooter.com



During my last two decades in the shooting business I’ve noticed a few trends. Rifles in particular have changed quite a bit. In the late 90s, bolt-action rifles either had a wood or synthetic stock. Some had blind magazines, some had a hinged floor-plate, and a couple had a simple detachable box magazine. Fast forward two decades and you wide spread adoption of detachable box magazines, and a third choice in a rifle stock, a chassis system. When I was standing behind the gun counter twenty-something years ago, I would have never guessed this would be the case!

Chassis are different than stocks in a number of ways. Unlike a piece of wood that can swell warp or bend, or an expensive fiberglass stock that requires a good deal of work to properly install and bed, a good chassis will have a aluminum bedding block that holds the action in place. The chassis typically free floats the barrel and the adds a detachable magazine system. For precision rifles, chassis have become the go to “stock” solution, and, until recently, chassis were fairly expensive. Modular Driven Technologies, has recently introduced the Oryx Chassis, a complete chassis system for the bolt action rifle with an MSRP of less than $400 ($399 as of June 2019).

Unlike many more expensive chassis on the market, the Oryx Chassis comes ready to install with all parts in place. It has a butt stock, magazine system (less magazine), and pistol grip installed. Simply removed your current factory rifle from the stock, place it in an Oryx Chassis, secure it with the provided hardware and you are ready to shoot better.

Given my long history with MDT and MDT products (I had published the first review of an MDT chasiss in the USA) I was excited to hear about the Oryx and received one that would fit a Remington 700 short-action to review. Chassis in hand, I had the chassis around for a few weeks waiting for the perfect test rifle, then I found it, a mis-marked Remington 700 ADL in 223 Remington that I paid $298 for shipped to my FFL.

MSRP on this particular rifle is in the $500 range, I couldn’t pass it up. This isn’t a heavy barrel varmint gun. This gun came equipped with a standard profile barrel that has a relatively slow 1:12″ twist (for the lighter bullets typically used by hunters). After testing and evaluation with some hand loads, the best five shot 100 yard group I was able to produce was .628 MOA which is fairly impressive, especially when you consider the factory trigger was set at over 6 pounds!

While it was a great buy for the money, I couldn’t help but think the stock was lacking. Many factory rifle stocks suffer from the same range of issues, they don’t have an adjustable length-of-pull, the comb is fixed, no detachable magazine system, barrels are poorly free floated and the bedding surfaces in are fairly substandard. This seemed like the perfect task rifle for the Oryx Chassis.

Rather than install the Oryx at my shop, I decided to do it in the field. My plan was I’d shoot the rifle in the factory stock, swap it for the Oryx chassis and fire it with the same 5 loads. While this meant a pilgrim installation on the tailgate of my Silverado, it would show me how easy installation was.

To install the Oryx, the rifle needs to be safe and empty. As an added safety measure I like to remove the bolt on rifles when I am working with them. On the 700 ADL, this requires the removal of three socket head cap screws (above). The barreled action can now be lifted out of the stock.

The Remington 700ADL also requires the extra step of removing the blind magazine from the bottom of the barreled action. This magazine is secured with a small screw. On most other guns, including the Remington 700 BDL and Howa 1500, this process is even easier since you are only removing two action screws.

Installation of the chassis is now fairly straight forward. The barreled action is dropped into the Oryx and the two provided socket head cap screws are used to tighten it in place. I like to rest the chassis on the recoil pad in a vertical position when I tighten a barreled action in place. I find this helps ensure that the recoil lug on the barreled action is making adequate contact with the appropriate surface on the chassis.

With the chassis in place, the rifle is now ready for the range. The entire process takes less than ten minutes, at which point you end up with an AICS style detachable magazine system, adjustable length of pull, M-LOK fore end, vertical pistol grip (interchangeable), aluminum V-block bedding system and adjustable comb. Pretty cool, huh?

As a reminder, the rifle was equipped with a Nightforce Steel 20 MOA base and a Leupold Mark 4 4.5-14 scope with M1 turrets.

What’s function without looks? Well, the Oryx looks pretty sharp as well!

I’m glad I did the Oryx swap at the range. I was only a few minutes away from having shot the rifle in its factory configuration when I settled in behind it. I was immediately pleased by the way the Overmolded rubber pistol grip filled my hand and allowed my wrist to relax in the prone position. While a traditional rifle stock is comfortable to shoot offhand or carry in the woods, they are difficult to shoot from the prone position. This issue was immediately rectified.

With the help of an Allen Key, I loosened the two screws on the cheekpiece and adjusted it up slightly. This, along with the pistol grip and bipod now much further in front of the rifle made for a stable shooting platform. I couldn’t wait to start getting some rounds off.

In case you didn’t read my Remington 700 ADL review (even you should have), these are the five, five-shot groups I fired with the 50 grain Nosler Ballistic tip at 100 yards. I’m running new Starline brass, CCI 400 primers and Varget powder.

My best group, shown above, was .658″ (.628 MOA). Let’s see how the same loads in the same barreled action would do with the Oryx Chassis!

Wow, best group .428″ (.409 MOA)! Keep in mind I shoot real guns and publish real groups, I was really impressed with this increase in accuracy. No doubt that I could improve things even further by swapping the factory trigger out for a Timney 510 and working on some more hand loads!

The table below shows differences in group size before and after the Oryx Chassis was installed.

The table above lists the size of each five-shot group for each of the five loads tested with the factory stock and then Oryx Chassis (I calculated percent change by subtracting the factory rifle group from the Oryx rifle group, dividing by the Oryx group and multiplying by 100%). Three of the five test loads were smaller with the Oryx. When all groups were averaged together, the Oryx Chassis groups were 19% smaller, with the best group for each being 54% smaller with the Oryx!

I am very impressed with the Oryx Chassis. In this case, less optics and rail, I paid $298 for the rifle and installed it on a $399 rail. Total price for the rig was less than $697! Even if you couldn’t score a 700 ADL for that low of price, you could still easily build a nice heavy barrel chassis gun for less than $1,000 (I’d consider a basic Remington 700 SPS Varmint as a donor or a Howa 1500 Barreled action from Brownells). I’d say that is great news for a lot of shooters!

So what are my thoughts on the Oryx Chassis?

  • Solid Value– For less than $400 you get a solid aluminum chassis with a AICS style adjustable magazine system, adjustable length of pull (via shims), M-LOK forend, adjustable comb, overmolded rubber pistol grip and enhanced accuracy!
  • Great ergonomics– In the adjustability department, chassis always beat stocks. The Oryx is no exception, with a few minutes of installation time you can make your rifle fit you the way you want it too.
  • Increased accuracy- I gained an average of 19% increase in accuracy over the 5 loads with the best load being 54% smaller in the Oryx. .4 MOA from a sub $700 chassis rifle system, I love it!
  • Easy installation– simply remove and replace a couple screw and you are in business!
  • Big fan! I really like the idea of a complete aluminum chassis system available to shooters for less than four hundred bucks!
