MDT Oryx Chassis

About as hard as removing 2 screws, moving the action to the Oryx and putting the two screws back, takes less than 5 minutes. It would take less, but on of the screws is under the mag release to you have to install that separately after the two action screws.

Looks good man, any issues with mags feeding? Stupid question here but are you using the mag that came with the chassis?

Magazines work excellent in the .473 bolt face Americans ( 308 Winchester, 243 Winchester, 6.5 Creedmoor and so on.) A magazine is not included with the chassis as we cannot predict what caliber you have. It's an AICS pattern magazine well so there are lots of options for magazines.

Thank you for the response! I was trying to figure out if the magpul ones would work also.
 
Hey josh I have a ruger American predator in 6.5 cm. How easy would the install be for the oryx considering where the action screw is? Also would the short action 308 mags offered on the website work directly with my gun? I have the standard predator not the version that is AI mag compatible from the factory. Thanks in advance.

Its easy like rcmig said. The mag release is held in place against the cross/retaining pin under its own spring pressure, take some pressure off of it by pressing on the release and you can drift the cross pin out with little to no effort. At that point its just the action screws like any rifle. But unless youre pressing on it specifically to remove the retention pressure its solid and you dont really have to worry about it falling out on you.

Magpul 7.62 AC P-Mags can work, they generally require a bit of fitting since they are optimized for a Remington 700.
 
My MDT 30-06 length max (think it’s 3.560 or 3.570” but can’t remember exactly) is working great in the oryx shooting 284 Win @ 3.273”. Rounds feed fantastic but It is a little harder to get in the chassis than some others. Every found feeds great though so can’t complain.
 
Has anybody tried to modify that oryx chassis with a bag rider? I’m also considering adding some weight to the back end as I’m running a heavy varmint barrel. My groups are all sub .5” with Berger 180 hybrids and also 180 eld-ms but I want more...
 
Considering switching to a chassis for my Ruger AP 6.5 CM. Oryx is probably top of my list given the value. Lots of good info in here.

I've been evaluating two different versions of bag rides from Jamer (https://www.jamerllc.com/) One vision is shorter, wider and really locks into a rabbit ear bag for shooting from a rest and the other is long and narrow and works well for a squeeze bag. Both versions slip on in place of the LOP spacer. I have the first one on my 6.5 and the other style on my .223.

Thanks for the link. Going to save that for later.
 
Those look nice I might pick one up. The long skinny one is for squeeze bags is that right? Don’t use rabbit ears much anymore except on my solely BR guns.
 
I am looking at a Mossberg Patriot Predator in 6.5 PRC, which seems to be near the limit of a short action. It is a fairly recent variant of the Patriot, and I would like to drop it into an Oryx Chassis. Is there any modifications to the stock or mag well, or the recommended magazines I should be aware of?
 
I have two patriots in 6.5 PRC but left them
in their original stock. I have an oryx inlet for savage axis and didn’t need anything else other than the 30-06 mag which is a little shorter than the LA of most mfg.

You can go to MDT’s website and get answers for Oryx as well. They were great on getting back to me. I didn’t know that they had a patriot inlet on the Oryx.

You would need a no-binder plate magazine to modify the feed ramp of the rifle.
 
I have a Rem 783 that I am considering this chassis stock for; are there any Rem 783 owners on here who can share their experiences?

Are there any magazine concerns that I should be aware of etc?

@DRAGON64, I have an Oryx for my .223 783, super happy with the set up. I got the MDT polymer .223 magazine and it's fed great from the start, a little tight going into the mag well maybe but nothing horrible. PM me if you have any other specific questions.

Thanks for the feedback. My 783 is chambered in 6.5 Creedmoor, so I would think the MDT polymer 308 mags would work best?
 
The chassis is machined for AICS mags so you can run the MDT ones or other AICS mags too. I used the MDT Polymer mag because it's one of the few AICS compatible options for .223 but you shouldn't be limited to just MDT mags in the chassis. One day I took my chassis out and forgot the MDT mag so I threw a Magpul 5 rounder in to use as a sled, it worked fine.

Yes, the polymer 308 mags are a good choice alongside any true AICS pattern magazine.

I prefer the MDT mags to the AI due to the fact that the MDT mags have a ramp up on the follower...and the AI has a sharp wall. Where this affects me is.....Sometimes I'm single loading a round....for ELR...and with the MDT mag I can simply toss in a round and run the bolt forward. With the AI mag I have to press it below the feed lips and have it feed in from the mag.

Some people like the hard stop of the AI...because it lets you know you are out of rounds...but I count pretty good...so I know when I need a mag change...heh.

So remember that in your Mag choice.

I purchased the oryx chassis for my remington 700 22-250. The only caliber magazine recommend is the 308. I thought this was strange since the rounds are different lengths. I figured oh well, maybe they know something I don't. I filled the magazine with 22-250 went to chamber a round and it ended up in the front of the magazine facing down, I removed the round and tried to again. the round still wants to point down while trying to chamber.

I called the nearest oryx dealer and they sent me out a 22-250 magazine from legacy. This magazine would not insert and lock correctly. Frustrated, I called them back and explained the issue. They stated they sent out the wrong magazine and sent me out the MDT magazine in the 308 caliber. Still thinking... how can a 308 magazine accommodate the 22-250. I waited for the package to arrive. Well it arrived a week or so later and still the same issue,

Trouble shooting mode... lining up 10 rounds of 308 caliber and 10 rounds of 22-250 it is clear that the 308 rounds stack straight up and down in line with the magazine.

Where the 22-250 are shorter, they start to curve down thus the reason why they want stay cuddled in the magazine and not chamber.

The web site states for remington model 700 short action rifles. When researching magazines, the only magazines found were the 223 and 308 calibers. I call the dealer in Nevada and talked to the local gun shops here in Californina, all said the 308 caliber mag is the correct magazine.

I took the rifle and magazines to a gunsmith to get his opinion. He came to the same conclusion that the 22-250 rounds do not sit correctly in the magazine or feed to chamber correctly using the MDT 308 magazine.

I guess my question would be.. Has anyone had a similar issue and what was the fix?

Thanks in advance.

Basically everyone has that issue with 22-250 in aics mags as it has so much case taper, as you saw when you stacked em up.
Its why banana clips are ideal for cases with heavy taper, though unsupported for an aics pattern mag.

See how when these are stacked its all basically up and down with solid contact along the entirety of the case body from the rear all the way forward.
1583957645408.png


To get constant contact along the case body with a heavy taped case it has to curve, if you were to stack them up straight there would be lots of space towards the front which enables them to fall down in the front with a straight and even follower.

Try to stretch the mag spring to put more pressure at the front to keep it from nose diving.

Thank you for your reply.
I thought about spring placement but then there would be an inconsistent pressure as the spring tension releases if that makes sense. I was brain storming today after posting the original post and came up with an idea of placing a wedge between the spring and plate to keep the spring neutral yet left the front up to keep the rounds level ( if that makes sense) but I will loose probably one round in place of wedge. It’s all trial and error.
Just curious what others have done in the past.

We suggest our 308 Winchester magazine for 22-250, however, we only suggest 4 - 6 rounds at one time.
 
With respect to your suggestion.... I have heard this suggestion from my search to find a fix. Since the chassis says for model 700, I would think the chassis would be designed to accommodate the current magazines for the correct caliber on the market. Using a .308 partially filled seems to be a band aid to a known issue.

The issue is the taper on the casing which causes it to stack incorrectly in the magazine once you get above that round count. It is possible if you build up the front of the follower you could make it work.

It uses AI mags which were designed for .308 not 22-250.

The oryx is designed to use AISC mags Not rem 700 22-250 mags.

22-250 in a rem 700 inlet is a very small segment of the market. I don’t think you quite understand the how much time, effort, and money it would cost to bring a 22-250 specific mag and chassis to market.

I understand what magazines support the chassis. It clearly states that on the website.
It says nothing about using a .308 magazine for 22-250 round or partially loading a magazine. as suggested here. (this would be tribal knowledge)

I posted this in search of a fix to an issue with using a 22-250 with a .308 magazine. It doesn't seem correct though it appears it is practiced.

Not a discussion on a small segment of the market or all aspects of designing a new magazine.

Thanks for the inputs, I'll figure something out.

Any other mag latches fit this, or are replacement parts available? Recently fully seated AICS and MDT mags have been falling out of my .308 Howa Oryx with almost every shot, very odd.
Yes, we have parts available, likely a slightly weak magazine spring. Please contact Oryx through the support icon on their website.

 
@MDT_OFFICIAL Is there a trick to assembling the mag catch? I disassembled my Oryx but then decided to put the main parts back together to test feeding with the new cartridge. Getting that spring and pin back through was an adventure.

Yes, you need a slave pin, which you can either make out of a Q-tip cut to the right size or send us an e-mail and we can send you one. Also, here is a video for how to install the latch.

Do the folks at MDT know about any mods that guys have been doing on this chassis to add weight to butt stock? I'm thinking about some hollow bar for a bag rider though have already bought a bag rider... that or adding some steel as a spacer ring... any thoughts or suggestion would be greatly appreciated...

Hey I just got your bag rider and am trying to install it. Do I install it next to the butt stock or do I put the spacer next to the butt stock? Does it matter?
 
Got the parts installed and the new spring is noticeably stronger. Thanks for the excellent service!



I tapped the butt for a short pic rail to mount an accupod, and later switched to a homemade aluminum bag rider. That printed bagrider looks like it has enough meat to epoxy in lead slugs, or weights could be strapped under the cheekrest. If you have a waterjet handy,--steel buttpad spacers....
Thanks ill look into that.

I just found a picture and did the same...
 
Has anybody found a way to add additional weight to the rear end of the Oryx chassis? I have one in a savage axis inlet with a bull criterion barrel and need just maybe an extra pound somewhere close to my shoulder. I’ve thought about substituting one of the spacers and some how adding a lb in one somehow but am not all that mechanically inclined.
For $400 ($450 for me w vertical grip) it really is a solid value... I’m shooting 284 Win and it’s my only rifle w that cartridge but it shoots solid .35-.55 MOA on 75% of groups @ 100 yards but I can feel it would be better with more weight. Any thoughts?

If you have the means you can have some steel milled/waterjet cut in the shape of the LOP spacers. Should get you some extra weight.
 
You could also make a bag rider out of rectangular aluminum or steel tubing that can attach with two bolts into the flat section on the bottom of the stock. You could then fill with lead shot. If you heat the tubing with a small torch and melt the lead into one big ingot you wouldn't need end caps.
