Convert Your Glock to a Rifle with AMG

Did you know, it is perfectly legal to convert a handgun into a rifle (assuming it is done in the correct order)? Taking advantage of this, AMG (American Marketing Group) is offering the “Lock, Stock, & Barrel” kit to convert Gen 3 & Gen 4 Glock 17s to rifles, legally.

The kit arrives with a 16 inch replacement barrel, a new recoil spring, and a stock system from Phoenix Technology (which is permanently attaching, unlike the 1SHOT recently released). The stock is a standard M4 affair and is adjustable for length of pull or can be swapped with any mil-spec offering.

To solve the inevitable issue of reliable cycling adding in significantly more mass, the barrel uses an “accelerator” which is basically a gas port giving the system more energy to cycle (in much the same way a piston is used in a suppressor). Still, 124 grain rounds are a minimum.


Now, the conversion is only one-way. It is illegal to convert a rifle back to a handgun so buy and install the kit knowing that the Lock Stock & Barrel Glock  cannot be a handgun again (in the eyes of the law).

Update: Our eagle-eyed readers pointed out the err of my ways. It is legal to convert a handgun to a rifle and back again so long as no NFA violations occurred during the steps. See ATF ruling here. 

Those interested in the kit can pick it up from their dealer network (AMG does not look to have a website). Retail pricing is pegged at $499, but I have seen versions of this down as low as $250 through the various auction webpages.

Hank Strange has a video below demonstrating the installation and usage on a Gen 4 Glock.

    That’s depressing. I guess it’s cheap enough, but if you combine the price of the pistol and kit, you’re running up there with some of the established PCCs that accept Glock mags. You don’t have much in the way of rail space, either. Since it’s a legal rifle, you’d think they’d have a system that would attach to the existing light rail. Then again, maybe possessing that with a kit un-assembled would be felony territory since you’d have a mechanism to convert a pistol to an AOW?

    Besides, really, we all know the fun is in getting ANOTHER gun that hits out further, not converting it from one to the other one-way thereby losing one for good… 😉

    • BattleshipGrey

      I agree on the price in that you’re getting close enough to other PCCs to make this seem not quite worth it. I have been wondering when someone would produce a 16″ barrel for a Glock though. Maybe if they sold the barrel separately, maybe it would work in something like a RONI, so you wouldn’t have to do the NFA route.

      • Sianmink

        That barrel in a RONI? that might work nicely.

      • noob

        I like the plan with the roni. the increased barrel length would squeeze more velocity out of the weapon and the increased sight radius would help your iron sights.

        The only wrinkle would be if the recoil booster unit on the barrel is as reliable as the legendary reliability of the stock glock.

  • Evan

    This would be a more interesting product if you could legally convert it back to a pistol.

    • BattleshipGrey

      You should be able to. IIRC, you have to be able to convert it back. That’s part of the reason the Beretta Neos rifle kit and the Tompson Contender kits exist and were allowed by the ATF.

    • TITAN308

      You can, the article writer is in fact incorrect. See ATF ruling 2011-4

    • I was incorrect. Thank you, readers!

  • PeterK


  • bull

    i think the mechtech way seems better…
    also according to them its legal to convert it back.

    • Edeco

      Had been my impression (some old story about people doing it with Contenders, probably in a brown/avocado/harvest-yellow kitchen in a split-level ranch) but I wasn’t sure I wasn’t mistaken or out of date.

  • Edeco

    Nine or so inch barrel, pencil profile with that accelerator for G34 please. Like so that it will work with 115 gr etc, ideally. I want to make an artillery Glock.

    I have a 9 inch from LWD but it’s thick and no accelerator so needs 124 gr +. Rifle status not desired, I wouldn’t want a foregrip on the rail anyway, too floppy.

  • Emir Parkreiner

    You state that the conversion is one way, yet that is categorically untrue. A rifle-pistol conversion is illegal, but a pistol-rifle-pistol conversion is perfectly legal so long as there are no NFA violations during the later half of the conversion. An official statement can be found online. I would have included a link but it kept getting caught in the spam filter.

    • imachinegunstuff

      Like the Beretta NEO kits

      • Emir Parkreiner

        Or the Thompson Contender. There are many examples.

    • Fixed. Thank you.

      • Emir Parkreiner

        You’re welcome but there is one last thing. Due to the overzealous spam filter, I couldn’t actually post the direct link. Since you copied the incomplete link, your “See ATF ruling here” is just underlined text.

    • JK

      The fact that that’s from as recent as 2011 demonstrates ATF’s notorious capriciousness.

  • Mitch

    Ummm… MechTech. Please and thank you.

    • Mike Price

      I had one of those Mech Tech set ups. Real pain to get it locked in and heavy.

  • wildbillb

    i just want that barrel. the stock seems WAY to small to work like a rifle stock 😉

  • TITAN308

    As someone else pointed out Ruling 2011-4 by the ATF states you can infact convert from a pistol to a rifle back to a pistol. I would advise a little research and re-posting the article with accurate information.

  • Carl

    This is probably the stupidest product of the day.

    • Sam Green

      Your not alone in that regard.
      Funny day today, I took my neighbor and his wife to the range today

  • Hensley Beuron Garlington

    I think its pretty sweet. Options are wonderful. I think attaching a lightweight, M LOK guardrail to the rail under the Glock, would be useful for a longer site picture and aftermarket site options and accessories. Or just throw the thing into a longer version of the Ronin G2 or KPAS. $250 for the kit isn’t bad and if you can just get the barrel for cheaper and buy your own Ronin or other stock system, seems like we may have another “Barbie” platform to accessorize like the AR.

  • DetroitMan

    So you buy a $500 kit to convert a $500 Glock into a rifle. For $1000 you could get a much more effective rifle.

    • Vitsaus

      Stop injecting logic into the fanboy’s dreams.

      • mosinman

        Shut up 1911 shill!!!1!!! the Glock is the only handgun you’ll need and now it’s the only Rifle you’ll need!!1!!!! 11

        • General

          They should have gone with G20 10mm.

    • DIR911911 .

      or spend the 500 on another glock and learn to dual wield like a real MAN.

      • Beju

        As somebody whose mother is from Hong Kong, you raise a good point.

    • iksnilol

      Well, you get a PCC with the same controls, parts, ammo and mags as your pistol. So it does have the commonality advantage.

      Would love something like this for a CZ75.

    • gunsandrockets

      Or buy a SUB-2000 and keep the Glock.

    • JK

      MSRP, bruh.

  • me ohmy

    cannot convert back to a pistol… that is total dogshit.
    the carbine conversions for a pistol have been around forever.
    it is perfectly legal to make a pistol into a carbine and then return it to it’s former state, the same pistol was registered as a pistol originally. you arent make a new conversion.

    • Yes, I was mistaken. Thank you.

      • me ohmy

        no problem and thanks for taking my words as just a person tired of bad information on the internet…..nothing personal

  • me ohmy

    ALSO, you could do the SAME exact thing with a permanently attached hollow shroud which made the original barrel length 16″ or greater with no booster needed for function.

    • iksnilol

      You don’t think the weight of the shroud attached to the barrel would cause problems? 😛

      • Sianmink

        He means a 16″ shroud with the standard barrel tucked way away inside. made of plastic or aluminum it shouldn’t weigh as much as a 16″ hardened steel barrel.
        The trick would be permanently mounting that to the frame.

        • iksnilol

          If it is mounted to the frame it doesn’t count for the barrel length. Even if made out of alu it would still affect the operation.

          • Cymond

            Hmmm … maybe a heavily skeletonized aluminum muzzle extension.
            Of course, of the diameter was any larger than the barrel then you couldn’t get it into/out of the slide.

      • me ohmy

        depends on the style of shroud…
        but yeah it can

  • DIR911911 .

    kind of funny how the author says the conversion back is illegal when that is exactly what the guy in the video does. are we supposed to forward this to the atf? 🙁

    • I was mistaken. Thank you readers!

      • KestrelBike

        I come here to learn, and the last thing I’d want is to have that ability stifled by egos not willing to admit when they’re wrong at the cost of accurate knowledge being at the forefront.

        So, cheers and thanks, Nathan, and the rest of the TFB crew!

  • Beju

    I just want the barrel so that I can pull a ridiculously long barreled pistol out of my pants and feel like the Joker from the Tim Burton Batman movie.

    • JK

      Sarco has a 16″ 1911 barrel for about a hundred bucks, if you’re willing to go that route. IMO, 1911 styling is a bit more appropriate for the Joker than ultra-utilitarian Block styling.

      • Secundius

        @ JK.

        Fake Suppressor Barrels are CHEAPER, Vary in size from 4-inches to 14-inches. Longest, is STILL less than $100.00 USD…

  • iksnilol

    Just convert it in right order.

    Put on the barrel before the stock, remove the stock before the barrel (I think).

  • TheNotoriousIUD

    Man, that is ugly as sin.

    • MrEllis

      It looks like a some sort of loom banged a Glock and didn’t stick around to raise it…

  • With a Glock MOS or one that has a Mini Red Dot on it – I can see this.
    For a pistol with just regular iron sights on it… that extended barrel is… kinda silly.

    • MR

      Maybe a clamshell adapter to provide a rail up top. I’ve got one on my Walther to provide a spot for my See-All open sight. Seems to work pretty good so far.

  • allannon

    This seems like a problem intended as a solution to a problem that doesn’t exist. Could have a Glock and a sub2k cheaper, or just a bit more and get a proper PCC (and still have your Glock).

    • Sianmink

      That’s assuming you can find a sub2k

      • allannon

        That goes without dating when discussing most Kel-Tec products.

        But given the indirect nature of buying this, I suspect it’ll have similar supply issues. 😉

  • Anonymoose

    I’d rather just get a Glock 21 SBR’d and put an ENDO stock adapter, long slide, and 9″ barrel in it.

    • You can get the endo stock thing for $17 on dealextreme.

      • BattleshipGrey

        Really? They used to be like $150 or something like that.

        • Cymond

          Well the one on DX isn’t a real one, it’s a clone. I don’t know if it’s good or junk, but $17 is cheap enough to risk. MAYBE you could use it with an arm brace as an experiment before getting the tax stamp. (I’ve heard some claims that the Endo adapter doesn’t give a good sight picture).

          • BattleshipGrey

            Interesting. I wondered if it was a clone or if he outsourced some of his product. Either way I’m actually tempted for $17. Though I would feel bad having been a reader of Endo for a while. I always thought Mike’s pricing was too high though.

          • Cymond

            I remember it being expensive, too.
            Maybe he dropped the pricing? A complete AR tube and stock is often around $50, so there’s no reason for a complete kit to cost $150.
            I do think it was $150 for just the adapter….

            He probably does outsource the production, but the ones on DX are still probably fake. They used to have a lot of counterfeit Magpul products on DX, and it’s well known that Chinese companies counterfeit a wide variety of gun parts. Arguably they’re meant for airsoft, but many of those counterfeit parts end up on Amazon & eBay without any disclaimer.

          • Marty Ewer

            Glad to see Mike lowered the price on his adapter. I think he will sell a bunch of them now. (It was originally $150. Then $100. Now $35.)

          • The DX one is likely from the same mold, as it has the ENDOTACTICAL logo and eberything :/

          • A darn good clone with the same molded logos and whatnot. Either from the same factory or a mold of a very easy product to replicate.

            Check DX’s site for item #113648

          • Cymond

            Oh I’ve seen the item and considered ordering. There are countless highly believable clones of Magpul parts. Just google it. There are numerous articles on how to spot a fake. There are also airsoft versions of Aimpoint sights with completely realistic labels and trademarks.
            If Magpul and Aimpoint clones are a problem, it’s enough to make me wonder about this, too. Maybe it’s real, maybe it’s not.

          • I built my 3rd AR out of as many bootleg/aliexpress parts as possible. Grip, pins,buffer tube, KAC handrail, gas tube, gas key, mbus sights, elcan spectre 1-4x.

            Not too fond of the bootleg elcan, but everything else is holding up well.

            Somebody had to try them.

          • Cymond

            How many rounds do you have through it? I’m working on a “budget” AR pistol right now. I need a new low-profile gas block to fit under the handguard I bought. Unfortunately, the really cheap ones are aluminum, and I kinda think that’s a bad idea.

            I think there are 2 kinds of parts one shouldn’t cut corners with: those that affect operation/safety (bolt, barrel, gas system, trigger, buffer) and those that are likely to simply break.There’s very little danger in a cheap flash hider or stock. It’s easy to make a decent plastic grip, it’s much harder to make an electronic part that withstands recoil. I’ve always been tempted to buy one of those $40 green lasers from Amazon/eBay/whatever, but the reviews are so mixed. Some people have no problems (but they never mention what kind of gun they have, how many rounds they fired, etc), other people have nothing but problems. I’d hate to waste money on something that I know is probably going to fail.

          • 800+? myself, and my buddy had however many rounds when I let him use it one weekend.

  • TITAN308

    Just a heads up, your hyper-link to the ATF ruling does not work.

  • Cal.Bar

    Yeah… don;t try this in CA without adult supervision. First, you have to get the bloody thing up to 30 inches overall length. Then you have to afffix a bullet button to necessitate a tool to drop the mag OR you can disable the pistol grip somehow AND you have to pin that stock so that it can’t be shortened below 30 inches while in rife configuration. This is just fraught with felony potential. If the barrel is not long enough or swapped out with the factory barrel without the stock first being removed you have a SBR (state AND fed violation) Forget or remove the bullet button = assault weapon and a CA state violation.

    All this to get a 30″ pistol caliber carbine you can just buy in full length from the get go. Not worth it in CA

    • Sianmink

      It’s not a felony if nobody saw you do it.
      Nonsense laws require nonsense solutions.

  • Devil_Doc

    For all this trouble, why not just put a KAK Shockwave onto a regular glock? Am I the only person that saw the amount of flex and whip going on with the barrel and the stock?

  • datimes

    Looks like a good way to poke your eye out.

  • The stock looks like a discount ripoff of the one that endo mike sells.

  • Mike

    Or you could get a Hi point pistol, carbine and 1000 rounds of ammo for that price.

    The Endo AR15 adapter is available on Gunbroker for $45. Can’t beat the price.

  • Mike Price

    The long 16″ barrel is available for the Glock now. I will have to dig up the company that makes it.

  • Mike Price

    About $200 you can turn your Glock into a really light compact carbine with longer range.

  • Mike Price

    With Taurus CT9’s cheap and hi cap mags now available for them on Gunbroker, it’s cheaper to just buy the carbine.

    • JK

      If you want a Taurus. Heck, Hi Point carbines are cheaper than just the kit, and don’t have a reputation for ND ing when you sneeze.

      • Mike Price

        True, they just need to rework it for a double wide magazine and lighten it up some.

      • maodeedee

        A pistol caliber carbine is just a civilian version of a sub gun. Sub guns are supposed to have hi-cap-mags. The mnhi-points do not come with hi-capo mag nor are they an option and the aftermarket mags for the hi-point are not reliable.

        • JK

          If you want a civilian sub-gun, you really need to get one of the MasterPiece Arms MAC clones. Z-mags from Shockwave are a bit pricey, buy are reported to be quite reliable, even in full auto models.

    • maodeedee

      How reliable are those mags? With a Glock you can get 33 round mags that are 100%

      Try reading the article a little more carefully. It says, “To solve the inevitable issue of reliable cycling adding in significantly more mass, the barrel uses an “accelerator” which is basically a gas port giving the system more energy to cycle “

  • Cloward Piven


    • maodeedee

      Why not? I’d like to see them make a less expensive kit without the AR collapsible stock, just a plain fixed polymer stock, that would sell for about $250.

      Then make it for both the 10mm G20 and the 45 ACP G21 and I’d be interested.

  • Ben

    This is pretty hilarious from a UK standpoint. The idea of Americans converting their pistols into rifles like this – this set-up is what we have to do to get pistols over here.

    • Secundius

      @ Ben.

      Yeah, Right! BBS, British Superiority Syndrome. The Country that Produced the STEN. What a Piece of SH|T, that was. Makes the French Chauchat, look like State-of-the-Art. Up to 30-meters GREAT, beyond that “PROBLEMATICAL” at BEST (a Fire Hose, on a Sprinkler Setting)…

      • Ben

        In Britain one of the ways we can own “handguns” is to take a pistol, add a rifle length barrel and a stock to get it over OAL. I think this Glock set-up could be imported to the UK potentially, although I’m not au fait with all the laws etc (from both sides of the pond).

        The ‘hilarity’, such as it is (irony would be more accurate), comes from seeing Americans modifying a pistol in the same way we do, but to get round a completely separate set of arbitrary laws that have a different intention. I probably didn’t express this well enough in my original post.

        You don’t need to use “@name” thing with Disqus.

  • Secundius

    A bit of Nostalgia, reminds me of the early to mid 1960’s. The Television Show: The Man from U.N.C.L.E. with his Convertible 9mm Pistol, that could be converted into a Carbine. I think they even had a Toy for that for awhile…

  • Secundius

    There’s this Really Nice Glock Revolver in .45 APC coming out, Hopefully Soon, They call it the G-21R, I think it would Look Nice as a Artillery Pistol or Cavalry Carbine…
