Desert Tech MDR Prototype

MDR

Thanks to Henry Reed for this tip.

Desert Tech recently posted a video showing a functioning MDR and does it look like fun. I found it interesting that the shooter does not wrap his thumb around the pistol grip. A technique usually seen for long range shooting.

    If I’m shooting fast, sometimes I’ll remove my thumb from around the pistol grip. It’s just to avoid the tendency to push the rifle forward with that hand. This way, your primary hand is 100% committed to pulling the rifle back into your shoulder. If you’re doing a lot of movement, it’s not ideal; but from a stationary position, I feel like it helps to keep the rifle steady.

    This is the bag daddy 7.62x51Nato Version right? SWEET! Some one actually Following up on there Compact Bull…. Magpul….

    • Seburo

      Wonder which language can PDR be an acronym for vaporware?

  • patrickiv

    Front sight?

    The forward ejection is cool, though I wonder how easy it is to clear a malfunction.

  • Martin Grønsdal

    huge recoil, or does this guy fail to absorb it well?

    • TheSmellofNapalm

      How well can you keep your muzzle down when shooting .308 on full auto?

      • Joshua

        Even in semi it looked like it kicked like a mule with large amounts of muzzle rise to top it off.

        • Martin Grønsdal

          That’s what I mean too, I used the G3 in the army and a decent shooter could almost avoid muzzle rise on semi auto. On full auto, however, hehe…

          • Tomaso

            Huge weight diferance between this bullpup and the G3 …IIRC G3 is close to 11lbs. Pretty sure the MDR is under 8lbs.
            Add to the fact this is a rifle round not an intermediate round, the recoil seems low to me, The shooter is working hard to hold his sight picture..( thumb is red holding down on the select lever ) . Having shot an RFB a few times and own a FAL , I realy like the look of control this bullpup exhibits considering the caliber (7.62 NATO/308) …like the foward ejection too.

      • echelon

        The MDR is 5.56 if I’m not mistaken. Those didn’t look like 308 cases being spit out to me…

        • TheSmellofNapalm

          Do your research, the rifle is built around 7.62. Also read the YouTube comments.

          • echelon

            I guess I was mistaken. All of the previous info I’d read/seen on it indicated that it would be available in up to 5 calibers at some point, but at SHOT during an interview the rep said they were going to lead with the 5.56 version…

    • Anonymoose

      It does look like a bit of a thumper. Anyone know if it’s short-stroke or long-stroke?

      • TheSmellofNapalm

        Short-stroke

    • Ebil

      It’s a prototype (not proper spring or buffer) and does not have muzzle device.

  • Seburo

    Desert Tech is one of the few firearm companies that is actually innovating . Instead of putting crap into an AR or AK and calling it a new rifle.

  • Batouman

    We don’t need no stinking sights up in hea!!!

    • JumpIf NotZero

      Heaur.

  • Trey

    It might help him better handle the recoil if he holds the thing better with BOTH hands

  • Joshua

    The only issue I hace with these are the overly complex ejection system.

    • TheSmellofNapalm

      It’s the same ejection system we’re used to, except they’re simply redirecting the cartridge. I don’t see the issue.

      • Joshua

        You really cannot see the difference between this and the AR bolt?

        No offense meant, but cmon they are night
        night and day differences. I would hate to see a spent brass case slip and land in front of that spring loaded holder and then have the BCG go forward pinning it in place and also trying to feed another round. And trust me I can think of it Murphy will see that it happens.

        • TheSmellofNapalm

          I applaud them for trying something new and functional. Roller-delayed blowbacks weren’t perfect when they came out, and nor was DI or short-strokes. Given DT’s reputation I wouldn’t be surprised if they worked out any kinks by 2015.

          • Joshua

            Not so much kinks but unless they go to a new ejection method the scenario I layed out can and will happen, there are other stoppages I can see that would be overly complicated to clear compared to a normal ejection system.

            Murphys law and all that.

          • Krav0pt

            It seems like it might be presenting a problem already. If you go to watch the video on Youtube and read the comments regarding why the charging handle is reciprocating an individual named Nick Young, with supposed insight at DT, replied “The charging handle will be non-reciprocating it is rubbing on the bolt carrier causing it to unintentionally reciprocate some of the time. We have already addressed the issue in the next phase of development. 🙂 Thanks for noticing, very attentive!”

            I agree with you regarding Murphy’s Law. An unintentional reciprocating charging handle on a compact bull-pup configuration could present a lot of problems.

        • hod0r

          Ejector levers are at least as old as the Krag-Jorgensen and equally simple and reliable as a plunger-type ejector. ARs aren’t immune from double feeds either. If the MDR ejection cover is faulty simply remove it. Your only argument is “this isn’t what I’m used to!”, the same argument M14 users had for the M16 when it was new.

    • mosinman

      i actually like that they’re trying something a little different.
      too many times we see the same system used over and over, and it just seems like creativity is stagnating imo. (i’m not saying there’s anything wrong with the tried and true ejection systems)

    • Paul Epstein

      It’s worth pointing out that you can simply open the tube/cover and fire the gun as pictured, and it will eject in the traditional way. If Murphy strikes, and you can’t eject through the tube, you’re no more disabled than if you were using one of the many other bullpups like the tavor which operate that way 100% of the time.

    • Tomaso

      From a Shot Show video, they show how the ejection door can be flipped up to make eject like normal and clear malfunctions..

  • Smokey_the_Bear

    nice to see progress, I was drooling over this gun when I saw it (through youtube) at shot show this year.

    @ 3:03 “It’s a non-reciprocating charging handle.”

    Sure looks reciprocating to me…

  • CaptainSlaughterboard

    Oh yeah eject shells from dat tube! That’s what I was talking about(9 months ago).
    And it’s functional with full-auto too? Good, good , good!
    Watching this rifle working is damn fun. So cool. Can’t wait get real one…

  • SM

    If they can keep the price reasonable and keep up with demand, the MDR will go far.

    (hehe, it rhymes)

  • N703

    Also the same grip for the MP5. Easier to hit the selector that way.

  • echelon

    Wish he would’ve switched to south paw so I could see how close those shells are spitting out from his face. I’m intrigued but it still makes me nervous. As of now I’m still liking KelTec’s RDB downward ejection system better…hopefully time will tell.
