MasterPiece Arms Releases New Glock 9mm Carbine

Introduced with surprisingly little fanfare, MasterPiece Arms has announced a new Glock-magazine compatible carbine, the MPA20DMG. Based on their ubiquitous 930DMG, the new carbine features a full-sized grip for flush compatibility, a 16″ barrel, and full free-floated quad rail.

Those interested can pre-order the carbine for $966 direct from MasterPiece Arms. Included with the carbine is a side-folding stock, scope mount, adjustable sights, and some “decal grip grip panels.”

    Grip grip panels.

  • Stephen

    Quad rails were cool until people realized that gravity isn’t going away.

    • USMC03Vet

      Quad rail weight is only an issue for potato chip curlers.

      • Stephen

        No. It’s an issue for anyone who has finite energy.

        • CavScout

          Tell that to anyone that has to carry a M249 or M240 through basic combat training, their MOS schools, various other schools, or deployments. Contemplate a 25lb weapon as you claim a few extra ounces on a 7lb weapon is too much.

          • Sinosparo

            When fractions of a second matter, the inertia difference a 5lbs carbine vs 7lbs one can mean defending your home unscathed or taking a hit. There are M240’s with barrels as short as a typical AR-15, doesn’t mean it becomes the weapon of choice for the pointmen.

          • Stephen

            Sure, a 25lb vs 7lb weapon is going to be a huge difference no matter what context. It also is a distraction from my point. Which is this: adding unnecessary weight is always counterproductive. It may only be a few ounces. But hiking across any terrain for long distance has a way of creating a strong desire in any human being to shed any weight they can. Even if it is only measured in ounces. The most healthy and strong person has a finite amount of energy before rest is needed. No matter how big or irrational their ego is.

            Additionally, very few people get added value from all the extra rail space on a quad rail. And they get no extra value vs an equivalent keymod rail that provides the same function in a lighter package.

            A quad rail adds dead weight. The end.

          • Ian McCollum

            I think those people would appreciate light guns more than anyone else. Look at it this way; 5 pounds less gun means you can carry 5 pounds more ammo (or food, water, radios, grenades, etc). Of course, that whole issue is irrelevant to this MPA thing, which will obviously never see a combat zone. But still, a full quad rail on a long-barreled MAC-10 is just dumb.

      • buzzman1

        Good comment. I get tired of hearing people whine about how heavy a 7 lb rifle is.

  • FWIW

    Not the prettiest gun I’ve ever laid eyes on…

  • Tom

    But why so ugly? Lets be honest pistol calibre carbines are for the most part toys* so making your PCC dead sexy (like the Berretta Storm) is a wise marketing move and its not like MasterPiece Arms are confined by import restrictions.

    • MR

      This line seems to be based on the old MAC submachine guns, then they tilted the pistol grip for Glock mag compatibilty. I prefer the vertical mag well/pistol grip myself, but those mags are a bit harder to find and can be more expensive.

      • Tom

        Yep, MasterPiece Arms have been making MAC clones (well closed bolt) for years now.

    • Phil Hsueh

      Kind of reminds me of a Mac-10 that’s had its grip replaced and an extra long barrel with quad rails attached to the front.

      • Tom

        Pretty much what it is. Now the Mac 10 is a lovely looking weapon (in a sort of cheap utilitarian sort of way) but this looks horrible.

        • Anon. E Maus

          I agree. There’s so many ways they could have made a MAC-10 pistol into a carbine without it being this ugly.

    • John

      >Lets be honest pistol calibre carbines are for the most part toys*

      It depends on the carbine. I hear nothing but good things about the Hi Point one, for instance, and there’s an undeniable tactical benefit about having a long arm compatible with both your pistol ammo AND your pistol magazines.

      However, this looks like a MAC-10 with a rail system and a long barrel on it. Probably why they didn’t advertise it very well.

      • Tom

        It is a MAC 10 with a long barrel and rail, that’s pretty much all MasterPiece Arms do – Make MAC clones. And there is nothing wrong with that but as a pistol they are overly large and heavy and as a rifle they are in an anemic round with little benefit in weight or size reduction. Ultimately I (and your views may differ) see it as nothing more than a range toy and an ugly one at that.

        As for the advantage of ammo and mag compatibility, unless your running a suppressor and ideally auto then a pistol calibre weapon is just not as good as a rifle calibre weapon. Pistol exist because its not entirely practical to carry a rifle around all the time. Pistols are sidearms, much like the swords they superseded they exist not because they are effective (which is not to say they can not be) but because they are present.

        Even if you do have a full auto SMG then options like 300 Blackout are superior in most cases. Of course any gun is better than no gun but this is not something I feel like anyone is going to recommend for serious defensive work and certainly not something any agency which has access to proper SMGs is going to want.

        • El Duderino

          Totally agree. If you’re stuck with semi auto and a 16″ barrel, make sure it fires a rifle cartridge.

          If you’re able to buy full rock n’ roll with whatever barrel length you want (8″-12″ is generally considered the sweet spot for 9mm/.40/.45), well go wild.

    • sam

      I get your point, I mean, that is a popular point of view (that they’re toys). But I give them more credit, due to being easy to shoot well, pleasant-mannered in terms of recoil and muzzle blast, and efficient for the propellant burned.

      The appearance: I’m hoping a smooth tube, or one with just keyholes is somehow possible, that would fix it for me. Berettas, to each their own, but over-styled for my taste, whereas the classic velveeta-block-shaped receiver is fine by me.

    • Kivaari

      Import restrictions? Aren’t they produced in the USA? It is why all of the formerly European designs are made here. Since Americans can’t import receivers, trigger groups, barrels or any significant part, thanks to the re-evaluation of the GCA ’68.
      When ATF actually read the law, it stopped what had been a good importation based business model. Now we get American AK, Galils, SIGs, FALs and similar.

      • Tom

        That is my point they are made in Georgia so can all sorts of features imported arms can not.

    • Roderick Lalley

      TEN mm is not a TOY !!!

  • Azril @ Alex Vostox


  • nadnerbus

    A friend of mine got one of the standard pistol versions of this in .45 five or so years back. Unless they changed it, that thing is heavy. With a long barrel, quad rail and stock, I imagine it is even more so, and I notice there is no weight listed in the specs.

    I think it is cool that they brought back the old MAC 10 platform in a semi auto, but I feel like they are trying to do way too much with it.

    • nobody

      The 9mm pistols are quite a bit lighter at 3.5 lbs vs the 5.5 lbs of the .45 pistols. The mini 9mm weighs even less at 2.9 lbs.

  • Caesar Booty

    $966? I’ll pass.

    • Rusty Shackleford

      I’d much rather save $300+ by MPA using the standard 30SST handguard/top-end.

    • Mohammed

      Buy 3 high points

  • kregano

    Man, what is with MasterPiece Arms slapping heavy rails on everything?

    • Tom

      Because its Fantactical that’s why.

  • TheNotoriousIUD

    I don’t think it has enough rails.

  • Cal S.

    .40S&W, please!

    I know, dream on. I’m not a groupie/cool kid that has everything in 9mm, so I pay the price.

    • Nashvone

      Think of all the money you saved by switching to .40!

      • Cal S.

        Considering I started out with .40, it would be cost prohibitive to switch to 9mm. So yeah…

  • Michael Acuna

    Looks like a Mac-10 has been ODing on Extenze lol(^o^)

  • TheNotoriousIUD

    The fire selector in the second pic looks a lot farther forward.

  • Victor Lourenço

    Jesus Christ that thing is ugly

  • sam

    So much want! If I went with this I’d feel bad not waiting for the new Sub-2000 (to become available without using gunbroker) because I’m a George Kellgren fanboy*, but that truly collapsible stock! This has nothing to do my appreciation of the movie Escape From New York**.

    I wonder if the handguard is replaceable? I’d just want a simple tube. Also I hope the muzzle device is removable and that it truly is 5 lbs as the website says (or at least less than 6.75 or so). The price is scary, will have to stew on that, see if it can be expected to decline after a while.

    *because he’s the JMB of the 21st century. Sorry not sorry.
    **OK yes it does.

  • USMC03Vet

    When in the Snoop Dog/Weed skin going to be released for this?

  • David Sharpe

    I’d get it if it was legal in Canada.

    Long story short, I’m not getting it..

  • wetcorps

    Why do all new PCCs have to be around 1000? Seems to me people mostly want them as range toys and find that too expensive.
    I’m sure something around 3-400 that takes Glock mags and is reliable enough would do a killing. But maybe that’s not possible anymore.

    • El Duderino

      SUB2000…not a grand, not often found for $400 either, but they are out there.

  • Samson

    I would’ve loved an awesome Glock carbine in 9mm or even .40 but… this thing is even fuglier than the Beretta CX Storm.

    If Gaston Glock or shsll I say that if Gaston Glock’s home wrecking, family-destroying, gold and platinum -digging new wife and head h0e in charge would have signed off, we could all have been enjoying our Glock equivalent of polymer MP5s for years now. But they decided Glock Perfection meant, lets just spend the money we’ve already made and not let anyone try to do something new and exciting. Little buggers might think they’re better than us!

    Silly gaston and gaston-ho. Dont you know 9mm carbines are cool now? ?

  • Bob

    Cool, but for that price I can buy 3 Hi-Point carbines, a can of krylon and 2 cases of ammo.

  • Panzercat

    If I’m going to get something that big and overpriced, I’ll just pony up for the bigger caliber and SBR a PAP. $450 plus the $200 stamp will still be less than this.

  • JJTX

    Wayyyyyyyyy too expensive for what looks like an M11 with an AR15 upper.

  • wry762

    Wow, dat sticker shock. The price is up into Colt 9mm AR territory – and I can’t see getting the MPA over the Colt, even if the Colt costs a little more.

  • Leigh Rich

    Looks good

  • Anon. E Maus

    900+ dollars is an awful lot for a MAC-10/11 derivative. Aren’t they supposed to be cheap to make?

    Ditch the quad-rail, it’s needless weight, make a simple two-piece plastic handguard or something. It saves weight and money (can literally use any normal AR-15 plastic handguard, lets say Magpul or something).

    Folding stock is nice, but not necessary, make it a simple plastic stock.

    Flash-hider isn’t bad, but it’d be cheaper to just ship with a threaded barrel and a thread-protector on it.

    Not as flashy, not as TACTICAL, but cheaper and lighter, you could probably move a lot more guns that way if it was maybe 700 dollars or so, a lot of people would consider looking at it.
    It still is in cheap and abundant, and tried and true 9mm Luger, it still uses the Glock magazines, which are just as cheap, abundant, tried and true.

    I urge Masterpiece Arms to take note.

  • buzzman1

    Make this is a 10 mm and I might be interested.

  • Ergo

    If they had been smart they would have just made a 9mm version of the mpar556. this thing is uglier than Nancy Pelosi pole dancing in a 2 piece.
