Karl forgot his most important rule: change nothing before a match. One wouldn't think a slightly larger magazine would cause problems...one would be wrong.

The halo dmr is slowly coming together.

I have to say, MDR has shown a considerable amount of confidence (and more than a little guts) in giving you their product line to test.

Hand this over to 9-hole reviews. 6.5 MDR practical accuracy out to 1,100 yards.

Me: What caliber is your MDR? InRange: *Pulls out a rifle bag of parts* All of them Good video, it's interesting that the 25 round mags cause issues but at least there is a solution and a fairly easy one at that.

I hope you’ll show this against a spinner.

I know you've said these 2g ACM videos get less views but I want to say they're my favourite. Nothing backs up an opinion like a proof of concept, and the hypothesis/analysis attached to these videos is a real treat

Cool to see that rifle again. It is a clever design.

That barrel really took a pounding on the 3rd stage.

I always find MDR coverage interesting, and the quirks that come with it. But really cool to hear the non-bullpup guy of the channel call it the best bullpup on the market. Inspires a bit of confidence and might actually get this in the 6.5 now. Thanks for all you do at InRange, guys!

I have to say that watching the MDR eject the spent case when dropping the bolt is pretty sexy.

I’ve always rooted for the desert Tech after how responsive they were.

Gotta love Desert Tech! They do some real interesting modular designs

Master Chief: I need a weapon. Karl: Say no more.

Karl…after seeing several reviews, including yours a few years ago, I purchased an MDRX in 223 Wylde since shortly❤ after introduction. Since then, because I enjoyed it so much, I’ve sold off my AR15’s. A short while later I purchased a 6.5 Creedmoor barrel. Enjoyed that so much I purchased another frame and then had two MDRX’s. Some days at the range I shoot them both. Got rid of my AR10. Heck, had so much fun with my MDRXs, I ordered a 300 Blackout and got rid of my AR9 pistol. I’ve built a nice little collection of MDRXs. Me…I see myself as a protector, not a collector. I’ve learned in life that learning one weapon system incredibly well is a good thing. I have no problems with any of these MDRXs. You learn how to use them and maintain them, and they just run.

that case coming out when you dropped the bolt at the 6-rd mag change really surprised me. forgot about the wild ejection system the MDR has

As someone said here, I'm one of these bullpup fan boys, but god I'm so happy that you finally tested it in 6.5 CM, as it seems this is the cartridge this gun was made for. Thanks for showing us all of that! Keep up the good work!

Great to see another desert tech video. It's been interesting watching about the rifles since your first tests and the open dialogue between DT and the public.

Still screams shades of the 'Halo DMR' to me. And I want one badly as a result. 🤔🧐🥰😎🤓

"What ammo does this take?" DT: "Yes."

Love your videos on the MDR. Always great info and details on solutions when you run into any issues. Good stuff.

I was very curious about this concept, thrilled to see you running it Karl!

great review. I appreciate that you engage the manufacturer and its their feedback that is also in evaluation. sincerely hope channel support keeps you busy during these times!

Honestly this gun its so cool. I'm glad to see it representing what a good bullpup can actually be like

Great video, Karl! Looking forward to seeing you put the MDR through its paces again

Always nice to see more of this gun.

I bought ammo the other day, and there was 30-06 that was cheaper than any of the .223/5.56 they had. It's nuts.

Great video! I hope you post more of this soon! It's really interesting to see that 6.5 in action in a modern platform.

I've been looking into this gun and was literally just thinking what it would be like in 6.5 CM. Creepy lol, you guys are awesome.

I have a couple of the Magpul Bipods, 1 black and 1 FDE, and I am impressed with them. For a $100 you get a Made in The U.S.A. bipod that is lightweight, very well made and looks & feels solid. The price is perfect. Anything less expensive is either foreign or has too much going on with springs and bits that stick out and get hung up on anything. There are other well made, slim, made in the U.S. bipods but they are far more expensive. Magpul really has a winner here, so much so that that finding one in stock can take you on quite the journey!

Keep these videos coming I love MDR stuff

You're welcome! Thank you for the wonderful content!

The shooting channels I watch regularly are all very enthusiastic about the 6.5 and 6mm cartridges particularly for long range precision. That MDR looks so much better and more practical with the longer handguard.

demonstrating why even experts need to practice, even if sometimes its just to try weed out unknown issues. Ace gun.

Looks like another reminder to test your match setup as you will use it. Even if it is something as small as a different magazine it seems.

Is it the feed-angle/geometry of the entire cartridge stack (or the follower?) causing a problem in ANY 25-round magazine? Or is it only the polymer feed-lips of the Magpul mags specifically? I'm not particularly trying to defend Magpul... I just want to understand exactly what is the functional root of the issue. E.g., will 25-round Lancer mags work? Will mags of any capacity work as long as they're the straight-body style rather than curved? What's the real cause of the malfunctions?

love the competition videos!!!

I LOVE THAT FORWARD CASE EJECTION.

Thanks for making this video

Seeing Karl hit the blue barrel a few times at 9:00 was a cool reminder that even if you shoot something your bullets can penatrate they won't be accurate.

I love the MDR!! Beautiful rifle

that gun is shaping more and more into the gun of my dreams. and it is a bullpup. Dear lord.

Great video Karl!

Great channel, good job!

A taller scope mount will do wonders for you ability to get your eye aligned with a not so friendly eyebox. It's difficult to convince people that need to get the scope as close to the bore is counter productive most of the time and definitely a no no with a bullpup. I love the 6.5 bullpup concept; great video.

Love to see the MDR getting tweaked and improved

Karl, pro-tip on the Magpul bipod. When you go to raise the legs: with your hand behind the legs squeeze BOTH buttons at the same time and pivit your hand forward/up to move both legs at the same time. After doing it a few time to get the movement down, putting the legs up is as fast as putting the legs down.

High praise indeed.

Damn that 6.5 creedmore sounds good!

Desert Tech, a Utah company! Great shooting!

Best patches ever

Would have liked to have seen this in person rather than [REDACTED] at a shotgun match! That thing is super cool and I’m glad you found a way to get it to function reliably. I always thought the 6.5mm calibers were underrated. With 20 round mags and a better optic that thing will be good from CQB to long range!

What is the problem with clearing malfunctions with other Bullpubs mentioned in the video? As far as i know with the FAMAS, AUG, TAVOR and L85 you can see the same via the ejection port, as you can see with the AR15, AK's ect. So why would it be harder to clear a malfunction with those? I can imagine it be harder with the MDR or the FN P90 due to them beeing more different.

Like you said, those shot timer people must have loved that muzzle break. Double ears!

Thats a very good workout

Would it not just be easier and cheaper iif Desert Tech just bit the bullet and employed Karl to sort their guns out pre market release? Just a thought... Also wish we had these instead of SA80 / L98.

Nice little rifle!

Barrel killer! Just kidding, everyone does that sometimes, especially when using optics & on the clock. Heck, I have done it off the clock & with iron sights! Great video Karl!

I have the 1-6x version of that optic, and while I originally had it on that same mount, I found it was much easier to use with the cantilevered mount that holds it further forward.

6.5 MDR best MDR Yeah muzzle brakes are fine and dandy until you shot insides Could you do a comparison with/without muzzle brake and if you can with suppressor ?

I came around to 6.5 a while ago when I realized that it was at near price parity with any non surplus .308 Obviously there is some dirt cheap .308 out there, but for the improvement in performance I'll take it

The spent cases discharge in such a pleasantly neat little pile. That is impressive for such a powerful round. Not a fan of Bullpup designs, the MDR in competent hands is a least developing some curiosity. Helluva nice, functional, modular, and accurate rifle.

The unicorn gun with the unicorn round, a match made in gun heaven.

Good report! I paid for about 5 rounds this month...or less.

Karl with nice things to say about a bullpup? It really must be the end of the world.

Freaking nice vid and gun range

Very cool!

6:08 I must know where you found that Heaven's Gate Away Team Morale Patch. It's hilarious

I like the looks of that bullpup

I spend money on the Patreon so that this channel can tell me what I need to save up for.

I look forward to seeing your thoughts on the DTs. I was looking into them a few years ago and considering them for a long range rifle.

I just want to say thank you for being honest and forthcoming with information on all aspects considered. I own a 1-6 ACSS and have found it to be adequate. I'm wondering if putting a other 2X into the same optic has made the platform " less useful".

It certainly drills those targets 🔫👍👍

Really diggin' the patches there, Karl.

With your comment about muzzle brakes (on smaller intermediate cartridges) being unnecessary, would you include the stock AK-74 brake in that category? I was under the impression that it was a benefit to that rifle. Is it simply because they are disruptive to shooters alongside you, or are there other aspects of brakes that you find undesirable?

The 6.5 CM seems to be one of, if not the best balance of accuracy, kinetic punch, capacity, and acceptable recoil available today.

I love that you keep shooting bullpups, especially when you don't like them very much. It makes your conclusions more credible. I'm enamored by the concept, but as you have pointed out numerous times, the concept has flaws. I'm curious about magazine capability in 5.56: Does the MDR make it possible to shoot with magazines of a higher capacity than 30 rounds? Have you tried with a drum?

Did y'all see Cold Bore Miracles video with his MDRX chambered in 6mm ARC? It's whole heartedly impressive for such a small package.

Nice

wow a 500k rouble build?

Nice Rifle

Have you had any experience with the 1-6 acss, If so how was the eyebox on that?

50 years from now in the fifth call of duty modern warfare reboot someone is going to say the animation for the mdr is wrong because a case ejects during chambering of a fresh mag

With a 2,000-3,000 round barrel life on 6.5CM this is going to get real expensive real fast

How does a 5.56 MDR stack up against something like a AR-15 on time trials? Is there a significant difference in speed on CBQ style matches? And does it have better long range capability then a standard configuration rifle (like an AR-15)? I'm really curious to know if a best-of-breed bullpup is competitive with standard configuration rifles and carbines at short range stuff, and noticeably better at long range shooting, or is it just good "for a bullpup".

Lots of jams. Jams ruin my day. Soon as you start jamming your day is done on the score card.

Gotta hand it to Desert Tech to have the balls to send stuff to Karl. Its great to see the platform evolving.

Amazing patches

I really really really mean it when I say I really really really want a Desert Tech MDR

Whats that emblem on Carls mask? I know what the rainbow means, but i have never seen that emblem.

It's interesting to see tho how sensitive the MDR was to overgasing. Any guesses as to why that is? My guess is that the bolt travel is too short for the longer cartridges and more gas means the bolt bounces back too soon.

Cool shoulder patch!😉

This looks like a good modern service rifle contender.

The magpul bipod always looked heavy, been on the fence about it since it came out...

Stoppage can be cause by multiple reasons, i guess i saw one? When you rest your gun on the barricade hole with the front guard. You have no problem. But when you rest your barrel on that hole, you start jamming. Steel are flexible, it looks solid and straight but if you put some weight on it, it will bend, you take the weight off, it reflex back. If you put a caliper on such a setting, it may run 2~3 thou upwards, it is not big, you may shoot 1~2 inch higher. The key is, it is not true anymore. I won't say it is all the reason cause the jam, but i believe it contributed.

Top of my wishlist if I move to a free state.

What is that patch on Karl's left sleeve?

As an owner of an MDR I really appreciate you doing multiple videos on its different configurations. Correct me if I'm mistaken, but I believe you have the most testing on video with the MDR. I have the stock .308/16-inch set up and also use the 25-round PMAGs, so I'm very glad to know about the feeding problem should I ever convert to 6.5 Creedmoor. I would be very much interested in seeing how the MDR performs in .300 Blackout, should that opportunity arise.

It might be me but a few times I thought you were shooting into the drum/barricade (see @9:14 for example). Maybe an issue with a bullpup as the shortened profile does not force the shooter to clear the edge (so to speak). Having said that, I really enjoy your videos on the MDR platform. Seems like a game changer.

Did you ever do a longer range test/evaluation of this rifle? I love your content, ESPECIALLY about the MDR. Thanks for all your work and info!
