At Desert Tech, we make the rifles of the future designed and built to operate in advanced tactical scenarios. We do not, however, make the arbitrary, often archaic, firearm laws that may or may not restrict your ability to own the Micro Dynamic Rifle (MDR) in your particular part of the planet.

If the more compact, more versatile, more enlightened MDR renders your local laws impotent or even obsolete then so be it. The most anticipated new firearm of 2015 will be available at a dealer near you soon enough, measuring in at a federally appealing 27-inch overall length with an equally pleasing 16-inch barrel.

For those of you keeping score at home, that’s nine, ten, maybe even eleven inches shorter than the AR15 you’ve been hanging onto for sentimental reasons but still a full inch longer than SBR requirements. For most of you reading this, that means you get the MDR as pictured in all the upcoming, tacticool magazine covers, perfectly legal and painstakingly lethal for paper targets across the USA.

For the rest of you in less freedom-loving parts of the world, we present the 19-inch barrel, which exceeds the Restricted Weapon barrel requirements north of us (you’re welcome Canada), exceeds the overall length requirement for those down under (you’re welcome Australia) and even meets the Assault Weapon restriction to those just left of the politburo (you’re welcome California).


MDR - Barrel LengthWith a 19-inch barrel, the MDR stretches to a 30.12-inch profile give or take a pinned muzzle break or second amendment semi-colon, making it readily accessible and more universally acceptable.

Let’s walk it off together with that nifty 19-inch barrel in hand.

Canada requires an overall length of 26 inches or more (check) and a barrel 18.5 inches or longer (check).

Australia requires an overall length of at least 29.5 inches (check, mate).

California requires a 30-inch or more overall length (проверять).

Of course, we haven’t even gotten to the MDR-C which retracts to a scintillating 21.62 overall inches with the 10.5-inch barrel. I mean, have you seen this thing? From bang switch to muzzle break it functions at handgun dexterity without sacrificing rifle precision or punch.

But the fact that it’s 21.62 inches long means that it’s, well, 4.38 inches too short for anywhere outside of your playstation without SBR paperwork in triplicate plus taxes. Sorry. Write your elected officials and vote accordingly.

In the meantime, purchase the MDR-C. Complete the paperwork process through the FFL of your choosing. Pick up your MDR-C.

And try to remember that you’re dealing with Desert Tech, the rifle builder making the most compact, most versatile systems on the planet so, yes, the MDR and the MDR-C are built on the same chassis and the longer MDR forearm easily converts into the shorter MDR-C forearm (just like our SRS and COVERT sniper rifles) and vice-versa and the 16-inch and 19-inch MDR barrels can be used on the MDR-C.

Check. Check. And Check.

For the record, when we begin MDR and MDR-C distribution, conversion kits will be available as follows:

Barrel in 5.56 chambering: 10.5-inch   |   16-inch   |   19-inch

Barrel in .308 chambering: 16-inch   |   19-inch


Barrel Material: Stainless Steel

Barrel Process: Button Rifled

Barrel Finish: Melonite


Magazines for 5.56: Standard M16 size (multiple round capacities) and PMAG compatible.

Magazines for .308: Standard SR25 size (multiple round capacities) and PMAG compatible.


Note: This is not meant to be a comprehensive post on the firearm restrictions/requirements across the United States or other countries concerning Short Barrel Rifles. For example, California has an additional bullet button requirement. Also, Australia, like the US, has individual State regulations that could factor into your ability to purchase an MDR. Please consult your local Desert Tech dealer (domestic or international) for more details and assistance in purchasing this rifle. If you need help finding a dealer, please call us at 801.975.7272.

This is the first of several posts answering questions about the MDR and its upcoming release in 2015. If you have a question concerning this rifle, please email them to t.brown@deserttech.com and we will do our best to answer them by the January SHOT show unveiling.

    For Australia the MDR might make barrel length requirements but our laws prohibit 99% of the community from owning semi-automatic centerfire firearms of any kind. Unless you’re a professional contract pest control shooter, a firearms dealer or federally approved importer who has a ‘genuine need’ to have one of these, you’re never going to get approval to possess one of these unfortunately.

    Even though I’m a semi-free state, I’m probably still going to pick up a 308 MDR 19″ to replace my 18.5″ Squad Scout M1A. A 308 with 19″ of barrel is just enough for almost anything.

    Will there be a 6.5 Grendel conversion available?

  4. November 12, 2014, 8:56 pm   / 

    I would love one to replace my AK 47 but I would want it chambered in 7.62×54

    Really looking forward to the .308 version as a replacement for my DSA FAL squad rifle. I need something for CQB and closer engagements while still having the ability and power to reach out there. Bullpups by and large give the flexibility I have been looking for and just can’t find without compromise in more traditional rifle configurations. Plus outside of the Keltec there hasn’t been a .308 option out there worth my money (wouldn’t buy a Keltec ever). But when you look and read about the MDR it screams quality. Can’t wait!

    Greetings from the Largest democracy in the World (for those who dont know, its India and largest is populationwise . . . ha ha )

    This rifle looks awesome and I would love to visit the States to shoot it. Great Job guys
    Hope our Import and Right to keep and bear arms Laws get better and we get to enjoy these masterpieces.

    As long as it is a semi-auto I can get any of them… But will they even import to Europe?

    Will the MDR be available in the EU (where legal)? All the configurations would be legal in the Czech republic. I think Slovenia as well and probably other countries.

      I know the DTA-SRS is available in Germany (waffen-holthaus) and he hopes the MDR will also cross the pond.
      When it comes to German Law the .223 REM and .308 WIN 16” Version should be legal for sport-shooting, anything below a 16” barrel is considered unsporty.
      Hunting License Holders would also be able to buy the 16” 7.62×39.
      It get’s tricky with the MDR-C, long-guns have a minimum defined length of 60cm over here, so the barrels would have to be 13” for hunters to buy them without hassle.
      Anything below 60cm is considered to be a pistol only available for hunting license holders (but not normal pistol sport-shooting), but the amount of pistols a hunter is deemed to have a valid “need” for is two, and these spots are usually already taken by things like revolvers, rim-fire and 9mm pistols. But in theory the 6.8 and 300BLK MDR-C should be ok.
      The .223 Rem MDR-C has the illegal properties of a small diameter projectile center-fire pistol, so It will be off limits even for a hunters pistol permit.

    Thank you for remembering Canada!
    This is generating a fair bit of interest on CGN.
    As you note, 18.5″ is the cutoff between Restricted (range-queen only), and Non-R (logging roads, here we come!)
    However, in Canada, a flash hider DOES NOT count towards the legal length. So a 2″ FH becomes a 21″ total length.
    Do you plan on making clean, FH free, 19″ barrels?

    Looking forward to seeing you at Media Day!

    Just to clarify what I posted before regarding 18.5″ barrels.
    That applies to centre fire semi-auto long arms.
    Barrel length does not apply to either rimfire, or to manually operated longarms.
    (Because if I dont correct myself, someone else will!)

      If you look at the graphic above, the 18.5″ mark is just before the FS. So you and I are good to go!

    Please, please, PLEASE make 16 inch 6.8 SPC and .300 BLK barrels for the standard model! PLEASE!

    I understand and agree with the snarky point this post is making, but it would be a damn shame if DT built a 308 platform and then didn’t offer 24-26″ barrels in calibers like 6.5CM – for all of the same reasons you offer them in bolt action. I’m sure I’m not alone in looking at this primarily for 2.8″ and not 2.2″ opportunities. And those benefits don’t come with 16″ or even 19″ barrels. Overall length is obviously your chosen primary selling point, but I am much more likely to invest in this platform if I know conversion kits are coming that make use of the 308 magwell. An announcement to that effect would not detract from your overall length argument in any way, if anything it would enhance it. Just compare to the latest like DPMS G2.

    Also, any possibility of an AK magwell? Reliable stanag 7.62×39 mags don’t exist and an AK magwell would find you broadening your target market enormously.

    Any info you could provide would be appreciated and potentially move lots of people from “wait and see” to “early adopter” (I am one of those people).

    I’m crossing my fingers that you will offer a 10.5″ barrel in 300 BLK.

    The MDR has all my heartstrings.

    In Australia the MDR-C with the 10.5″ barrel should legally be a pistol, which would make it far more accessible for the average shooter.
    There are two hurdles, though.
    The first is that we have laws about “legal guns that look like illegal guns”, but with the recent approval of the Warwick WFA1 it looks like these laws aren’t being enforced anymore.
    The second hurdle is importation, because our customs office makes their own laws and they also ban “legal guns that look like illegal guns”.

    But if you can manage to trawl your way through those laws and send some MDR-C “pistols” down to Australia, I’ll happily pay top dollar for one.

    Get one to RCMP lab as soon as possible so it can get classified (seems to take forever). That way maybe can purchase one before 2020

    Hello everyone,
    To start, sorry for my English, I am only a poor French (lol). On our side, my wife and I bought a want MDR C 223 and 308. For the MDR in French law, no problem, but to find a distributor that is just what matters to me, the only one I’ve found advice me to take another brand ???? Hello commercial you have chosen. Is it possible to do directly with you ??
    American friends, I hi you and wish you good shot

    Please, Please, Please distribute the 300 Blk barrels this was the main reason why I have been following this rifle for so long. MDR-C in 300 blk would be the only firearm I would ever need in any civilian situation, so please!

      The MDR is built to the same quality standards as our other rifles, right here in the USA.
