Review: American Manufacturing Group Lock, Stock, & Barrel Glock 17 Conversion Kit

Pistol caliber carbines have seen a bit of a resurgence over the last year with the introduction of the CZ Scorpion EVO, the Sig MPX, and new HK MP5 clones. As you might expect, there are companies looking for a way to tap into the pistol caliber carbine segment through some interesting avenues. American Manufacturing Group sent us their Lock, Stock, and Barrel conversion kit for the Glock 17 to try out. The concept seems a bit strange, but what the hell, I will give anything a shot.

Before I headed out the the range I called my friend Scott to show him the new Lock, Stock, and Barrel Kit. We pulled out a tired old Gen 2 Glock 17 started the process of turning a pistol into a rifle. IMG_3879

After field stripping the pistol and setting aside the recoil spring assembly and barrel since they will no longer be needed. If you fit the kit to a Gen4 pistol, the recoil spring assembly is retained with only the barrel being replaced. IMG_3880

Sliding the barrel into the slide is just like inserting the factory barrel except you need to remove the locknut and piston to fit the barrel through the hole. As you can see in the photo below, there are three ports in the barrel to provide the needed gasses to assist the slide in operation.

Once the barrel is in the piston/bushing is slid over the barrel with the narrowed portion extending into the slide to keep everything centered. The next step is to thread the retaining nut over the threads, tighten it down to keep everything in place then back it off enough to center the lock screw over one of the flats in the threads.

The kit comes with a heavier recoil spring assembly for Gen 1-3 Glock 17s; the kit did come with an adapter for Gen 4 pistols, but the instructions recommend that you retain the stock unit instead. IMG_3883 IMG_3887 IMG_3888 IMG_3889

The Joker would be proud to take a shot at the Batplane with this guy. Sadly we found in testing that shooting the 16″ barrel without the stock was unreliable at best. I guess that isn’t a big deal since the kit is intended to be used as a rifle. IMG_3891

Attaching the stock is a simple operation, pull the latch and rotate it 90 degrees to retract the pin and slide the frame plug into the empty grip hole. Then make sure the back of the frame clips into the top portion and insert the pin through the lanyard hole. The entire process only takes a few minutes from start to finish making it a rather easy conversion. IMG_3893 IMG_3894 IMG_3895

It does look a bit goofy when it is all assembled, as long as it functions correctly I will gladly overlook the cartoonish appearance. While running some dry fire drills we did find that changing the magazine was a bit on the tough side due to the location of the button, with practice mag changes would get easier as well as faster.  IMG_3900

Shooting the Lock, Stock, and Barrel kit was a bit strange. While at the range we put the kit onto a Gen4 Glock 17 so that I could run the magazine release on the left-handed side. I found that this made magazine changes much easier than on the Gen 2 pistol.

Aside from some small hickups that I chalked up to cheap 115-grain ammo the Lock, Stock, and Barrel kit seemed reliable enough for range use. Based on the performance after shooting about 100 rounds of hot +P+ 124-grain defensive ammo I am not sure that I would rely on the conversion in a defensive situation, but as a range toy or to acclimate new shooters I can see a use.

My friend Mike came out with me since he was dying to try the kit out. We found that shooting at about 25 yards the conversion seemed to be accurate enough to be fun. We did try shooting the Glock with just the barrel fitted for fun; every single shot was a failure to extract. Since it isn’t intended to be used in that manner I can’t be upset about it not working. The same failure was present if you didn’t have the stock firmly planted in your shoulder. 4

The 5 round group was shot at 25 yards, the kit id more than accurate enough for range time. I was able to reliably connect with an IDPA target at 100 yards pretty reliably, but when I tried to push the kit past 100 yards on the rifle range, I didn’t have much luck. Shooting at distance with pistol sights is not an easy task. IMG_3539

After spending some quality time at the range with the Lock, Stock, and Barrel pistol to rifle conversion kit I can see a place for it on the range. As I stated previously, I don’t think it is reliable enough to be used as a defensive tool but could be really useful if you wanted to shoot cheaper 9mm while running rifle drills, want something different to shoot, or are working with a new shooter that is recoil or noise shy.

With an MSRP of $299.99 the buy-in price is a bit steep, but again, the group that this kit appeals to is very small. If you are looking for a carbine kit for your Glock that will fit into a backpack there aren’t many options out there. You can learn more about the kit on the American Manufacturing Group’s website HERE.

  • BattleshipGrey

    I might’ve asked this in the initial product release article, but if you bought this kit (or just the barrel assembly) you could put it in a Roni style stock and be legal right?

    Thanks for doing the review, I’ve been curious about this kit.

    • Patrick R. – Senior Writer

      Yes, but why not just buy the 16″ non-nfa Roni we have a review going live later today.

  • somethingclever

    I’d rather have a lever gun.

  • Nicholas C

    Interesting, I took the Roni Carbine rifle barrel and bought the ENDO stock kit for $35 and did the same thing here. The barrel is interesting, it seems very similar in design to the carbine barrels made by IGB Austria. The same makers of the Roni barrel. However the Roni barrel doesn’t use a piston, but if you google IGB Austria and look at their barrels, they have Pistons.

    • AMX

      Yeah, the barrel sure looks like a copy of the IGB system…
      Patrick, did AMG say anything about that? Licensing-wise?

      • Patrick R. – Senior Writer

        Nope. I am not about to ask, gettig involved in a possible patent war is it in my interest.

  • MzUnGu

    Sounds like a neat kit to throw into a bugout bag as a survival rifle for small games, if you are into that kind of thing. Cool.

  • Joe

    It’s too bad they couldn’t put a front sight post on the barrel to take advantage of a longer sight radius.

    • Willaim

      Red dot mount…or get the barrel to use with a KPOS system…there are variations that would make it worth while…

  • That long of a barrel on a Browning lockup has to look a bit silly as it woggles up and down, but otherwise this has all the makings of a crackerjack big budget Hollywood assassin gun.

    • Billy Jack

      Needs laser.

  • anonymous

    Does anyone else remember seeing similar kits to convert 1911s to 16″ carbines in the pages of Shotgun News way back in the early 1990s?

    • Richard

      I saw one at a gun show once, it looked cool, ugly, and funny at the same time.

    • William

      Remember? Hell, my dad HAS one…and its fun to shoot…especially with a P14 frame…

  • Martin Grønsdal

    Please, post photos of how the face looks like if the shooter is too close to the slide.

    • Patrick R. – Senior Writer

      It looks just at like a face. I didn’t experience any blowback.

  • TheNotoriousIUD

    Those pictures make my brain hurt.

  • Mark

    Woah wait. Isn’t it illegal to convert it back to a pistol after this? You can convert a pistol to a rifle, but not vice-versa, right? Seems like the biggest drawback.

    • bull

      you can turn it back.

    • BrandonAKsALot

      Pistol to rifle and back is fine. You can’t turn a rifle into a pistol though. Once a rifle, always a rifle. The ATF loves that sort of rule. This is the reason many people start their AR receivers as a pistol. Then you can pop rifle parts on and turn it back into a pistol if you feel like it. Better to have the option legally.

      • maodeedee

        Just think of how many lives that law has saved….. SARC/

        • mbrd

          …in washington deecee alone!

    • Nope. *IF* you start with a “pistol or revolver”, AND you put the barrel on FIRST, and you remove the stock BEFORE removing the barrel, it is fully legal to go back and forth.

      The Supreme Court of the United States ruled on this very fact decades ago. ATF just admitted it was precedentially binding a few years ago.

    • Cymond

      Here’s a citation showing it’s legal.

  • DetroitMan

    For the price of kit + Glock, you could buy a reliable pistol caliber carbine.

  • DIR911911 .

    hit every branch when it fell from the ugly tree

  • Russ Kell

    Where’s the free float rail?

  • Franivelius

    What about the Mech Tech Systems? You tried those? They look great.

    • Cal S.

      I wouldn’t say they ‘look’ great, but certainly better than this get up.

      • Anon. E Maus

        They look amazing in comparison, both aesthetically and functionally.

        I couldn’t see myself getting one of these kits over a MechTech upper

        • Cal S.

          Functionally, yes. Aesthetically… Well, beauty is in the eye of the beholder. 😉

    • maodeedee

      They look better but they cost a lot more. Not for the basic kit, but for the additional stock and sights that you need to be able to shoot it. The basic unit is $400 and a good red dot sight costs even more and stocks are a couple hundred extra.

  • Edeco

    Hmmm, I wonder about that booster and like an 8 inch barrel, if it would be too much.

  • Greg

    This is stupid, and no point to own. It’s also very illegal. It’s still a pistol…as it’s registered as a pistol, Putting a stock on it and putting it to your shoulder makes it illegal. Not considered a rifle,

    • Patrick R. – Senior Writer

      That isnt accurate at all.

    • iksnilol

      I guess all those T/C Contenders are illegal as well by your flawed logic?

      • Cymond

        But … but … but … the Contender has a specific court case that only applies to it!

        Actually, ATF did argue that it only applied to the Contender for many years. Fortunately, their 2011-4 ruling dealt with that.

  • iksnilol

    I’d rather just SBR it and use the factory barrel to be honest.

    • Patrick R. – Senior Writer

      No thanks. I have tried that before and found it to be more useless than I expected.

      • c4v3man

        It’s safe to say that the sbr route is the only way to get a suppressed glock carbine, right? There’s no way you could attach a can to the end of this barrel and get it to still cycle reliably?

        I’m surprised they don’t come out with an option for a barel that tapers down to .45 caliber that’s compensated the last 4-6″ with threading just before that, so you could at least throw a 45 caliber can over the barrel. Perhaps the weight simply won’t cycle, or feeding a suppressor via a compensated barrel isn’t effective. I’m aware of the ridiculous Sig MPX ruling, I would think it might get through if it wasn’t an obvious baffle stack.

        • Patrick R. – Senior Writer

          That would be safe to say.

      • iksnilol


        • Patrick R. – Senior Writer

          It is plagued with the same issues this kit has plus it is $200 more expensive.

          • iksnilol

            Wouldn’t the ENDO kit be cheap enough to offset the cost of the tax stamp?

          • Patrick R. – Senior Writer

            Barely. Then you can’t take it out of your home state without paperwork. Too much hassle IMO.

    • c4v3man

      Yeah, but if you already own a glock, and want to use it within a year, this is what you get. I’d imagine applications to the ATF are slowing down with the ridiculous wait times present, but you’re still probably looking at 9+ months at this point.

      • Patrick R. – Senior Writer

        I am planning on closer to two years in paper forms and 9-12 months eform. FML.

      • iksnilol

        true, but I think the SBR would be more rewarding and if you get ENDOs stock kit you can actually get it cheaper than this kit.

  • c4v3man

    Do you think a generic pistol rail to picatinny rail adapter with a red dot or lightly magnified optic would improve accuracy, or is this mostly limited by the mechanical accuracy of a long barrel in a short lockup system?

    • Patrick R. – Senior Writer

      It might. I have a feeling the rifle would still leave a bit to be desired when t comes to accuracy. After all, we are all used to AR-15 style laser beam accuracy. This just isn’t going to give you that.

  • Glock spock

    Why not add a hundred or 2 and buy a keltec sub 2k glock mag version? Makes more sense than this monstrosity.

    • El Duderino

      Plus you have 2 guns!

      • Doom

        add a hundred or two? well first you have to buy a glock, and then buy this thing, so why not SAVE 100 or two and just buy the S2K

  • Broz

    Reminds me of the 1911 ‘rifle’ kits once sold by Sarco (allegedly from Lebanon)

  • Lee Enfield

    Abortions like this exist because old man Glock refuses to make another boatload of money by making a pistol carbine. Apparently their banks are stuffed to the brim.

    • maodeedee

      Gaston Glock can’t live forever. Hopefully when he passes on someone will take charge of the company that believes in innovation.

      • jay

        I’m sure one of his wives is open to making more money…. ;-}

        • Doom

          ew gross, im not into milfs…Oh wait, did you mean a carbine? cause id totally bang that, in more ways than one. 😀

          • jay

            Well I’d bang a Glock Carbine as well! And if there was no Prenup, I might force myself to do the other as well…..

          • Doom

            Glock raifu will never cheat on you, just like Kalashnikov raifu will never cheat on you. they will bang on command as long as you love them.

          • jay

            Love em long time! ;-}

  • Rocketman

    I’ve always been surprised that Glock has never tried to make a submachine gun to compete with the Uzi and H & K MP-5.

  • maodeedee

    Here is a copy of an Email that I sent to AMG’s website:

    “Any chance that you’ll be making these for any other Glock models? I’d be first in line to buy one for my 10 mm Gen 3 Glock 20 SF,”

    I’ve been wanting to get the Mech Tech Carbine Conversion | Glock CCU Kit but prices start at about $400 and then you have to get sights and a stock besides. The Mech tech unit is much nicer looking especially with the collapsible wire stock instead of the M4 stock, but the price is more than what I’d want to pay And I’d gladly trade aesthetics for practicality.
    A 180 grain buffalo Bore JHP that’s doing 1338 fps out of a 4 inch barrel will do about 1573 fps out of an 18 inch barrel according to the website, “Ballistics by the inch”

    • Stan Darsh

      IGB Austria makes a similar barrel system at a comparable price for most Glock models, even the 10MM Auto G20.

  • John Daniels

    I was kind of almost interested until I saw it’s from the same guys who make the .22LR reloader kit, which is garbage.

    I refuse to ever buy anything this company makes.

  • PersonCommenting

    You need a red dot for this thing to be any more accurate than a standard glock. Yeah you get better velocity but without longer sight radius it will do little for accuracy.

  • PersonCommenting

    If you want a carbine just get an ATI Glock mag AR15. Pretty sweet guns if you ask me.

  • Tom Currie

    Did the author just admit to assembling and firing a “weapon made from a rifle” which by definition is any weapon with a rifled barrel with an “overall length of less than 26 inches or a barrel or barrels of less than 16 inches in length”? I realize that the BATFE has gone back and forth about the legal details of these pistol-to-carbine kits over the years, usually focusing on it being illegal to install the stock without installing the 16″ barrel, but within the definitions in the act, it would seem equally illegal to have the gun with the long barrel without the stock.

  • janklow

    this is possibly the worst-looking gun i have ever seen.
