[Big 3 East] The Unicorn H&K MP7A1

DSC_0113

A huge thanks to my buddy Alex of SB Tactical for bringing this down upon my request. The HK MP7 is a gun that is relegated to almost Sasquatch level of existence. There are very few out there in the US and even fewer people have seen them in person let alone fired one. Sure there are airsoft versions of the H&K MP7 and your occasional online personality has had trigger time with them like SMG Lee and Larry Vickers. So you can imagine my excitement getting to handle this little PDW.

I was most interested in comparing the MP7A1 to my Kel-Tec CMR-30. Yes one is select fire and the other is a 16″ barreled semi auto rifle. But the design concept is very similar. The cartridges are similar in size. The .22 wmr is not that far off from the 4.6x30mm when you compare data.

.22 wmr       Weight: 30gr  Velocity: 2300 FPS  Energy: 437J

4.6x30mm   Weight: 31gr  VelocityL 2362 FPS Energy: 506J

.22 WMR and 4.6x30mm

 

Ignoring my extended hand guard, the Kel-Tec CMR-30 is rather similar to the MP7A1

Shooting the MP7A1 on full auto is of course fun. I would characterize the recoil like an angry wasp hopped up cocaine. It seems to vibrate with pure anger. Ergonomics are both good and bad when compared to the Kel-Tec CMR-30. The CMR-30 suffers due to the European style heel mag release. The MP7 has the stereotypical H&K trigger guard style mag release. Since I am not accustomed to the MP7 it was a bit awkward feeling for the mag release. The MP7 has an ambidextrous bolt release which I prefer over the CMR-30 left side release.

With regards to the charging handles, I have to give points to the CMR-30 as it is a forward non-reciprocating charging handle. So you can operate the charging handle without needing to compromising your sight picture The MP7 charging handle is similar to an AR-15 charging handle you need to move your face out of the way to charge it. And there is even less to grab onto.

The stock release button is not ambidextrous. It is located on the right hand side of the weapon just behind the sling loop. You have to slide the button up to unlock the stock to allow it to open. The CMR-30 has the stock release right where your index finger rests on the trigger guard. Much more ergonomic.

 

Ever wonder where the serial number was on an MP7? It sits right under the body of the receiver near the back.

The MP7A1 is a fun little gun. I could see having a lot of fun with it just like I do with my CMR-30. Alas pining for H&K to make something is like talking to a wall. We can dream. If you want a small rifle similar to the MP7 then I would get the CMR-30 and chop the barrel down. Keltec should make a pistol version of the CMR-30. No not the PMR-30, I mean a pistol version of the CMR-30 and put a brace on it. Hmmm I should have a chat with SB Tactical and Kel-Tec.

    For a second there, I thought Alex C was trying to prank us again for April Fool’s Day by saying HK was releasing it for civilian sales.

    • Joe

      Civvy pistol rechambered in 9mm, under $1500 dollars.
      Happy 4/1

      • Alex Agius

        “rechambered in 9mm” – why? just get an mp5 clone

        “under $1500 dollars” – ha ha ha ha, seriously? this is h&K

        I guess they could import it as a pistol and have 922r sbr thing but i doubt the market is there, outside of people who want one because they can’t and/or want all military guns ever (because why not?) there really isn’t a market (especially without the fun switch)

        • Harrison Jones

          The market is there due to the gamer community. I’m really surprised more gun manufacturers haven’t tapped into this market directly.

          Someone correct me if I’m wrong but there are export issues due to german law regarding the export of the MP7 as a pistol due to the size of the cartridge and the gun being in a pistol format.

          • Alex Agius

            I honestly wouldn’t be surprised, it seems both the US and German governments do everything in their power to hurt H&Ks civilian sales

    • Cal.Bar

      I thought he was punking us by comparing and HK to a KEL TEC!

      • Chrome Dragon

        The new Kel-Tec is jonesing for some military contracts, and is going decidedly upmarket. I say this as someone who once owned one of their “downmarket” .380s, and found it a delightful little gun for carrying in warm weather. I’d probably carry a gun more often if I still owned it. :/

  • Adam D.

    Nicholas, two questions if you don’t mind:
    1. How do you operate the charging handle?
    Do you have to pinch the two “halves” together to get it to release?
    Does it latch on both sides?
    (I’m asking because I’m curious if a one side straight pull handle would be possible to design for it.)
    2. How was the gas blow back? Do you think it could be uncomfortable with a suppressor on?

    • CommonSense23

      The gun is a dream to shoot suppressed, but the suppressor makes it way to big for the round its firing.

  • thedonn007

    Damn you, now I almost kind of want a CMR-30 again.

  • Harrison Jones

    A CMR 30 SBR would sell like hot cakes! Not that kel tec has a problem selling anything.

    • Night

      A shame the same cannot be said of kel tec buyers.

    • Seems plausible. They’ve made NFA versions of the SU-16 and KSG. Just adjust the styling to be a little closer to the MP7A1, and it’d sell.

    • Mike

      They don’t have a problem selling guns, just making them enough of them to sell.

  • 2wheels

    I dream about the Army procuring these and allowing me to trade in my M4 and M9 for one of these…

    • Devil_Doc

      Why? Lol.. Was your M4 overpowered?

      • CommonSense23

        The M9 is overpowered compared to the 4.6

      • 2wheels

        So I don’t have to carry two weapons around when I’m working. As an EOD tech, I only carry them for self defense anyways. A PDW like the MP-7 is meant for people like me. I’d have a smaller lighter kit, and that’d be awesome.

        • Chrome Dragon

          Actually, that’s fairly solid logic.

  • Devil_Doc

    SB Tactical brace? Are people still using those? Guessing you all haven’t seen the KAK Shockwave?

  • Bjørn Vermo

    This is a PDW, not a sniper rifle. Why would maintaining the sight picture when operating the charging handle be an issue?

    • iksnilol

      I never understood how people managed to maintain perfect sight picture when operating any form of charging handle. It’s gonna jostle no matter what.

  • JumpIf NotZero

    “Unicorn”

    …. This is gun were ever actually available. The disappointment would be palpable! A surprisingly large proprietary .17cal $3000 blowback gun with $100 magazines.

    I love that there are always droves of people saying they would buy an MP7 in heartbeat but won’t touch a PS90 which is smaller and fits the role of a PDW infinitely better… FN can barely give them away. 99% of the appeal of the MP7 is you can’t have one.

    Another example of miswanting – and people saying they would buy something they won’t (like 10mm subguns).

    • Patrick M.

      but DEVGRU!

    • Hensley Beuron Garlington

      Amen.

    • The MP7 is actually a gas operated rotating bolt system.

      Which would be great for 10mm 😉

    • Machinegunnertim

      P90 also doesn’t have a stock or folding grip to fool around with when you need to get the gun into action quick. And many other attributes but the trigger and a couple of other quirks keep it from more popularity.

      I always thought that the P90 concept was better than the MP7 from a simplicity and caliber standpoint, both have odd features that we all wish could be tweaked and improved.

      I for one would not bother with the MP7 even if CDNN was blowing them out for $500 a pop.

    • Mike

      “FN can barely give them away?” At the price they are asking I would not call that giving them away. I would love one, but Too much money. Would love a MP7 type weapon.
      CMR30 looks nice, but I am reluctant to spend that kind of money on a Keltec

      • BrandonAKsALot

        They come up for sale between $1000-1300 in the last 5 years. It’s really not that much for an exotic firearm.

    • BrandonAKsALot

      The P(s)90 and F(s)2000 are very radical designs and people tend to dislike what they don’t understand. I can’t tell you the amount of times I’ve gotten the “space gun” comment when I have them at the range.

      • RickOAA .

        They are easy to understand, just awkward if one is used to…say…ANYTHING else…

    • Chrome Dragon

      If they ever want to give one – or a few crates – away, they know where to find me. Hell, let me know when I can get one for the price of a decent AR, which I can build for about $500 according to any number of build guides on blogs, youtube, or personal websites.

      I’d dearly love an AR-57 also, but let’s mark down another great idea I can’t afford.

  • YOYO BATOU

    I think these would be fun as well.

    • iksnilol

      That looks like something out of Fallout 1 or 2.

  • Marc

    “European style heel mag release”

    All mag releases are European style. The thumb button was introduced in the Borchardt C93 in 1893 and carried over to the Luger. Colt on the other hand made its first pistol with thumb button release in 1910.

  • Suppressed

    “There are very few (MP7’s) out there in the US and even fewer people have seen them in person let alone fired one.”

    I’ve read this 6 times and it still makes absolutely no sense whatsoever.

    • JoelC

      Maybe a few people have all of them? … and they are locked away somewhere. 😛

    • iksnilol

      Few MP7s in the US.

      Even fewer people have seen them in person.

      An even smaller subset of those who’ve seen it have fired it.

      • Giolli Joker

        Yep… that doesn’t make much sense.
        Let’s put it in numbers:
        10 MP7s in the US
        8 people have seen them
        6 people have shot them

        Wouldn’t you guess that each of those MP7s have been seen by more than one person?

        Let’s leave similar articulated sentences to Bilbo Baggins. 🙂

        • iksnilol

          Hey, this all could’ve been avoided if you guys got more MP7s.

          • Giolli Joker

            Don’t look at me, I’m not in the US. 🙂

          • iksnilol

            Hmmm…

            These silly Americans and their lack of MP7s.

  • James

    Is anyone surprised that Walther has yet to release an mp7 or ump clone in 22lr?

    They already have the mp5, g36 and 416 22lr.

    Heck they can even use the 22lr mp5 mags for the ump.

    The mags curve to much for the mp7.

    • Or a clone in .22 Mag for that matter.

    • Mike

      Want a .22 version of P90, MP7 and SA-80

    • Chrome Dragon

      Walther, or Umarex?

      I bought a couple Umarex products – one clearly marked as such, one not – and discovered new flavors and textures of loathing. The first – a pistol with an integral reflex sight – scraped my finger raw before the CO2 was exhausted. I bought it purely because of space-gun appeal and my jonesing for pistol optics. It was stolen; I didn’t miss it.

      The second was a Walther G22 airsoft clone. Even with five-amp ni-mh cells fresh off the charger (far better than the 800 mA AAs included with many similar guns!) it took a full second of holding the trigger to charge and fire. (Wheeee… pop!) The full-auto mode had a cyclic rate of 1 hz, and was activated by a sliding switch placed in a random location on the gun body’s right side. If it was any faster, the 10 round magazines would be an issue, but in truth, I was bored before I finished emptying the first magazine and it lost me when I squeezed the trigger to fire and no pellet came out – my trigger pull was too brief to fully charge the spring.

      If it kept the mainspring ready to fire between shots, I could forgive the abysmal cyclic rate. If I don’t spend a whole second re-zeroing on a moving target, I’ll probably miss anyway. If I have to charge and fire for a whole second, *that’s different.*

      I returned it the same weekend I brought it home. I still have the gift card, since the store I visited still only carries the crappiest parts of Umarex’s lineup.

      If Umarex ever seriously gets their poop in a group, I’ll consider their products. Their Taurus 24/7 isn’t bad, but much of that I attribute to Taurus’ seriously actually really good ergonomics. (At least, the old 24/7 with the “ribber” grip fit my hand like a goddamn *glove* – ymmv!)

  • Niko

    Yeah…almost the same…as your pictures bias for the same length: one is more than double the length after pistol grip. As you compare velocity from a 7,7 and from a 16 inch barrel. Great job, gun pro.

  • Marcellmgt@gmail

    HK will not make a Semi Auto only version for the US market. They have a host of reasons why including something about German Law.
    Yet they have sold Semi Auto SBR versions in Canada. After actually having handled and shot one, they can keep it. FN PS 90 is a far superior weapon with better ballistics. One can easily reload the 5.7 mm cartridge with easily available components. HK blew a chance to sell it’s “tacticool” toy in the US . Except for hard core HK fans it lost its audience.
