Bullpups don’t always get a lot of love for reasons most people who’ve shot them already know. First and foremost, their triggers are uniformly awful. That’s because of all the linkage required between the trigger itself and the sear that’s located all the way back behind the magazine…which is under your chin.

That magazine placement results in the second biggest gripe bullpup detractors have: slow and awkward magazine changes. Those two factors — not to mention the fact that bullpups are generally heavier — are a lot to overcome, even though the bullpup design has a lot going for it, primarily its wonderfully compact overall length and the resulting excellent maneuverability that gives you.

So…lots of people have sworn off bullpups, or never bothered trying one in the first place. And when TTAG got a chance to visit Desert Tech’s facility in Salt Lake earlier this month, we pretty much figured we knew what to expect. We might have been a little presumptuous.

Desert Tech is primarily known for two platforms, its MDRX semi-autos and its SRS bolt guns. In recent years they’ve announced a couple of other intriguing products…their Trek-22 chassis for 10/22 rifles and, most recently, the new Quattro-15 receiver that lets you use Desert Tech’s 53-round quadstack magazines in your AR.

First, we got a look at where it’s all made.

Completed MDRX rifles

But far better than hearing about the guns and seeing them put together was the drive we took out to the first rate North Springs Shooting Range near Price, Utah to give these things a try for ourselves. And shoot them we did . . .

I wanted to give the new Quattro-15 a try as Desert Tech had just announced it at SHOT earlier this year.

The Quattro-15 is basically a standard AR-15 lower with a double-wide magazine well.

That well is designed to hold Desert Tech’s new Quadmag-53 53-round magazines. Yes, fifty-three rounds.

It’s a quad-stack design that enables you to carry more ammo and shoot more between mag changes.

Desert Tech says the combination of the Quattro and Quadmag-53 mags lets you carry more ammo with slightly less weight and you can still cram them into most double size magazine carriers. The lower is priced at $224.99 and the magazines are $44.99 each.

I got to try one that had a giggle switch. That’s where you really appreciate the extra magazine capacity. You’re not locked into using the Quadmags, though. You also can use standard STANAG magazines in the Quattro-15 lower by using a small adapter insert Desert Tech sells for $20.

Maybe the most fun we had was shooting the 10/22 in the Trek-22 chassis.

That’s almost more fun that it has a right to be. We were easily plinking steel at 50 and 100 yards handheld from that fun, very compact package.

When the sun went down we added an Armasight CO-Mini clip-on night vision sight that combined beautifully with the red dot.

Desert Tech Calls the MDRX the ultimate truck rifle. You can probably see why. The bullpup design crams a 16-inch barrel into an overall length of just under 28 inches. Add a can — the one below is from Huxwrx — and it’s still a very compact, packable package that tucks nicely just about anywhere in your vehicle.

Desert Tech’s micro dynamic rifle has an adjustable gas system, non-reciprocating charging handles and you have the option of either side or forward eject (depending on the model you choose) on either side of the rifle. Yes, that means the MDRX is lefty-friendly.

As for those awkward magazine changes, Desert Tech has the traditional magazine release behind the magazine well, but they’ve also engineered in mag release buttons just forward of the trigger, right where your finger expects one to be.

Desert Tech makes it easy to change calibers, too. But maybe the biggest surprise from shooting the MDRX (and later the SRS bolt guns) was how good their triggers are. Once you shoot a Desert Tech bullpup, you’ll wonder why every other bullpup maker has been incapable of giving you even a decent trigger pull. The Desert Tech triggers aren’t only decent, they’re downright good triggers you’d expect to get on any good traditional rifle design.

Desert Tech may call the MDRX the ultimate truck rifle, but their SRS bolt gun gives the semi-auto bullpup a serious run for its money as far as I’m concerned. The SRS is Desert Tech’s precision multi-caliber rifle and we got to see what that means in action. They claim no shift in the point-of-impact from a barrel change.

We shot a 6.5 Creedmoor SRS at 1000 yards and were consistently hitting steel. Then  Desert Tech’s Jeff Wood swapped out the barrel, converting the rifle to 7mm PRC.

The barrel change was quick and simple, consisting of loosening four screws on the right side of the rifle and a locking nut on the left side (see Jeremy’s video here). Jeff then hit the same 1000-yard steel target on the first shot after the barrel change.

That was impressive.

Finally, I simply couldn’t pass up the chance to give Desert Tech’s big HTI rifle a go. Like the SRS bolt guns, it’s multi-caliber (.375 CheyTac, .408 CheyTac, or .416 Barrett are options) but this one had the .50 BMG big boy barrel on it. We were shooting steel at 600 yards.


Thank heaven and John Moses Browning the rifle had that honking Huxwrx suppressor on it to cut some of the felt recoil.

Shooting Desert Tech’s bolt guns was a real eye-opener. Not only is their precision impressive — especially when changing calibers — but it’s helped by the fact that Desert Tech has cracked the code on building bullpups with truly excellent triggers…something you just don’t see it bullpups from any other maker I can think of.

  1. Well I hope they sale a lot of them so those people can have a job.
    It’s good to see Americans working.
    Most of the able to work Americans I see are drawing a disability check or sleeping on a blacktop.

    • Six months prior I misplaced my work and after that I was blessed sufficient to falter upon a extraordinary site which truly spared me. I begun working for them online and in a brief time after I’ve begun averaging 15k a month… The finest thing was that cause I am not that computer smart all I required was a few essential writing aptitudes and web get to to begin.
      ) AND Great Luckiness.:

    • I haven’t shot a Tavor 7, but the Desert Tech triggers are equal to some of the best AR triggers I’ve tried. That’s saying something given the mechanics required in a bullpup.

      • Good article, Dan. Info, photos, commentary…answers pretty much all the basic questions and whets the appetite to want to learn more.

    • Better than. Still debatable as to whether the MDRX’s are ready for duty use. QC problems abounded, last time I looked into one. Really wanted them to succeed, CM or 30hate in a short package would be verrrry nice. Acc. was all over the place back then too, certain examples would do 1.5, and others 4-5 M0A.

      Maybe that’s changed in the interim?

  2. Looks nice but the whole “truck rifle” thing is questionable. I’ve spent my entire life in and around trucks and I just can’t see something like this being all that easy to wield within a cab. Although that wouldn’t stop me from buying this.

  3. I see positives and negatives like length, weight, trigger, etc but price point is a kicker with a “truck gun” where the fact remains of possible theft and $2k compared to a budget in the hundreds is a hard pill to swallow.
    Bullpups are one of those things that have never caught on but never die like a McDonalds McRib

    • Theft is the single best reason to never keep any firearm in a truck or any other vehicle.

      • It’s a way of life in places and needed.
        I run an overhead rack and lock it when I gotta go to the city.

        • Vehicles getting broken into for taking guns is a way of life for people net city thugs too.

      • Which is reason number 9876306552 I’m not there
        Can’t lose a $1k calf cause of “feelings”
        Neighbor just this week lost 3 sheep to a pack of drop off city dogs

  4. Theres affordable 338 semi bullpup”s (under 5000) on the market ?

    Would an cool suppresed rifle in combination with belt fed for long range fun and big game hunting 🙂

  5. Pullpup?

    I realize that typos are a TTAG tradition, but this has got to be a record. 😆

  6. “Pullpups?”

    The Desert Tech stuff looks nice … but my impression is there’s always been a lot of hype surrounding them and I’m usually not one for drama. So I took a different path.

    Overall I’m quite happy with my K&M bullpups (5.56 and .308). I believe they worked with Elftmann to get the triggers pretty darned good. They balance well, shoot well, and are fun to take to the range with both newbies and experienced shooters.

  7. Ya know i like the 53rd mag thing. I mean i like when the boundaries get pushed a little. I guess thats why I’m a keltec fan.

  8. Anecdotaly I shot a rifle class at Sig with a guy who used one of these. His rifle was the only one that didn’t survive the day.

    Cool gun, though.

  9. I’ve got a little experience with the AUG. Both semi and full auto versions. Two friends have .223 Tavors. My son has the .308. So. No thanks. Bullpups handle poorly for me. I suppose they have a center of balance. Somewhere around 3″ in front of the butt plate. The slow awkward reload was mentioned. However, it can be mastered. I’ve seen it. It still doesn’t look as fluid/natural as a more conventional reload. Short and handy does appeal to me though. With in reason. NFA be damned, I’m not interested in a centerfire rifle cartridge in less than 16″. That said, generally speaking, my shortest weapons tend to be my favorites.

  10. If you learn to shoot an 18” shotgun in “short stock” position your good to go in most limited space environments.
    Hopefully you’ll have ear-pro on for use in a car or indoors.
