How to Convert A Standard GLOCK to Full Auto [VIDEO]

How to convert a semi-auot GLOCK to full auto.

By Jake Hover via

First and foremost, a disclaimer: the creator of the video, Currin1776, needed very specific licensing to legally complete this conversion. This video was created for demonstration purposes only and is only informational. Don’t try this at home, kids. Once you are properly licensed, though, all you need is a new end cap, disconnector and a selector switch to make just about any GLOCK a bullet hose. And what else are you gonna do with those 33-round magazines?

    Hee hee…..I am totally, uh….. NOT going to make one of these for fun and/or teotwawki preparations.

    (think they bought it?)

    1. avatar Todd S says:

      Yeah… nobody here’s on a list…

      1. avatar Jason Baldini says:

        Screw them and their list, put me on the list.

        1. avatar bob says:

          I don’t think I have to ask anymore….

        2. avatar Blackhouse Down says:

          I’m already on the list “Comfirmed” M.I.B assholes asked me what my intentions were with the 500 lbs. of prilled ammonium nitrate I ordered. I was honest and told them it was for explosives to shoot just like tannerite. They were very nice and said by law they have to investigate these ‘unusual’ first time purchases. I asked them if I was ‘red listed’ and they said unfortunately yes.

          So I’m not worried about being on a domestic terrorist watch list… WTF they gonna do? Put me on it again?

    2. avatar Dustin says:

      And you certainly won’t buy one of those RONI things for it, either. In fact, you aren’t even going to own a Glock.

    3. avatar Removed_californian says:

      What do you mean he isn’t even going to own a glock? He doesn’t even own any guns. Guns are scary and kill people.

      1. avatar Joe R. says:

        … and then they die in fires at sea… ?

      2. avatar Realist. says:

        so do fists, so do knives, so does fire, so does electricity. so you better stop using them things too because they can kill you.

      3. avatar David says:

        Guns are not able to kill anything because i have had my .22 pistol fully loaded (it dont got a safety) on my dresser beside my bed an it aint never killed anyone that walked in front of the barrel only way a gun can kill someone is if the trigger gets pulled either from someone or something getting caught on the trigger when holstered or by getting dropped sorry for the typos an crappy english skillz lol

        1. avatar Nitrous says:

          Hey David,
          If you happen to have kids around, either regularly or periodically, you do know that there is a much greater chance of them dieing by accidental discharge than by fending off any one trying to do you harm…. just saying

        2. avatar LarryinTX says:

          Hey nitrous, you do know that 1000 times zero is still zero, right? If you are desperate to save the children, you should properly dispose of your 5 gallon buckets, since they cause more accidental deaths among children than firearms do..

        3. avatar bob says:

          I have to side with Nitro on this one.

          I have a few buddies that think the same way, they leave loaded firearms lay around the house, coffee tables, night stands, etc..
          Their excuse is, “I don’t have any kids and kids aren’t around”

          Then when I bring my kids over, they have gotten so used to having them laying around they forget there are loaded guns laying around.
          Now, you can teach kids not to touch them, and that works, after a certain age. but a 1 or 2 year old will play with EVERYTHING no matter how much you teach them.

          The point is, you are the adult, never trust a child to be responsible for you!

          After all, accidents do happen, they just do.

    Quite likely one of the most fun things you can do with your clothes on.

    1. avatar Gunr says:

      A pepperoni pizza comes close though.

  3. avatar uncommon_sense says:

    And what special licensing exactly does one need to “legally” convert a post 1986 firearm to full auto?

    1. avatar Eric Lampley says:

      From what I understand you have to be either a registered manufacturer or a class 3 ffl with a law enforcement demo letter (basically a letter stating a law enforcement office wants to evaluate a post-86 full auto gun to see if they want to purchase it)

    2. avatar pod says:

      There’s a few FFL/SOT combinations that will ensure the legality of doing this, but the most common one is to have a type 07 FFL (Manufacturer of firearms) with an SOT 02.

      I don’t think a demo letter is required in this case since how the heck are you supposed to convince a police department to sign off on something that doesn’t even exist? The demo letter is only if you are a dealer and you are looking to acquire a post-86 sample.

      For example, if I were a dealer (FFL 01 – SOT 03) I would need a demo letter to, say, acquire an H&K MP7 to have on my premises. The local PD would have to have an interest in one, and want to demo it with me.

      If I were a manufacturer (07/02), I could build the item myself sans demo letter, and then just show it to the police.

      I might be inaccurate on this. However, if I’m right, I think that the ATF probably gives manufacturers a little more scrutiny just to make sure they aren’t turning out automatic weapons for the sheer thrill of it…

      1. avatar Joe R. says:

        The ATF has airport dogs that can smell thrill on ya three miles before you even get near the range. There’s no scent blocker yet made that’ll overcome it.

      2. avatar TomD says:

        You’ve got it right. An 02/07 can produce them without a demo letter. The yearly ITAR fees keep most out of the game for the “thrill of it” though. If you have a rental business and host shoots to cover your costs you can be an enthusiast with a large post 86 collection it just needs to be for more than “I want machineguns” and at least look like you’re attempting to stay in the black financially.

  4. avatar Frank Masotti says:

    Wouldn’t you need to beef up a few things? Like the barrel, the frame, and the firing pin to keep doing that? Look fun as all get out though. 🙂

    1. avatar NDS says:

      Check out iv8888’s video where he shoots a converted G17 until it fails… Pretty incredible.

    2. avatar ShiningKnight says:

      Hence the reason they are using a G23 .40 pistol with a 9mm conversion barrel.

    3. avatar bob says:

      I’m not sure about the new ones but it used to be that all glocks are made the same, full auto or semi, the switch is really only the major change. Component wise they can take the abuse.

  5. avatar uncommon_sense says:

    By the way, why would anyone pay big $ for a 9mm sub-machine gun when you can just use one of these?

    And now for the $50,000 question: can you make a Glock fire full auto with a MechTech carbine conversion kit?

      1. avatar uncommon_sense says:

        I actually pulled up that TTaG article and it was not readily apparent to me, from the photos, if you could mate the full auto Glock lower with the MechTech upper.

        Er, now that I think about it, didn’t the video poster add the parts to the slide on the Glock — the slide being the “upper”? Therefore this design would not work with a MechTech upper as is. Correct?

        Having said all that, I’ll bet it wouldn’t be hard to incorporate the same feature in the MechTech carbine conversion unit.

        1. avatar Joe R. says:

          Video? ?

    1. avatar Ladale says:

      How can I turn my glocc 22 hand gun to a fully automatic handgun…In we’re do I get the kit to do it from

  6. avatar Rick K says:

    andy cuomo would absolutely soil himself if he knew this video was out there for public consumption.

    1. avatar Dustin says:

      So, why haven’t you sent it to him?

  7. avatar Curtis in IL says:

    I’m not too familiar with the Mech-Tech carbine conversion kits, but if you could modify one of them to do that, then you’d have something.

  8. avatar Tom in Oregon says:

    There’s another guy who makes an end cap with a swing type switch on the rear of the end cap.
    His web site says they are not for sale in the US. But the exact dimensional drawings are free to look at through the U.S. Patent office. ?

    1. avatar Geoff PR says:


      Google a bit.

      There is a real good chance you can find a pdf of that floating around on the web…

      So I’ve heard…


  9. avatar great unknown says:

    That last sentence about 33-round magazines is precisely the bulletin-board material the magazine grabbers look for.

    1. avatar Todd S says:

      You think they need any thing other than, “MOAR BULLITTS ARE BAD!!!”?

    2. avatar Dustin says:

      Do you think they’d back off and think for a second if it were a 30rd? A 5rd? You’re a fool if you run in fear of an attack that will come no matter what you do…

    3. avatar Tom in Georgia says:

      I say let them scream. Scream till their eyes bleed. Sure, a Glock FA conversion is utterly wasteful, extravagant, impractical, and so much more. But oh-so outrageously entertaining. And sometimes that’s all there is to it. Life is short 🙂


  10. avatar Fukem says:

    His is exactly what is needed for the coming civil war.

  11. avatar Sixpack70 says:

    The NFA needs to go away so I can make one of these myself.

  12. avatar Curtis in IL says:

    Looks like fun.
    But an uncontrollable gun that runs out of ammo in three seconds isn’t too high on my wish list, even if it was legal.

    1. avatar Chadwick P. says:

      That’s why they make those stock deals and beta mags!!!

    2. avatar Andrew says:

      i have shot a G18 at a GSSF match. It was surpringky controllable

  13. avatar Former Water Walker says:

    Probably NOT a good idea posting that HERE Dan-leave it on Youtube. I do love the video!

  14. avatar Paul53 says:

    I’ve seen European ads for a complete Glock back plate with the semi/auto switch built in. To paraphrase W. C. Fields’ comment comparing women to elephants “they’re fun to look at but I wouldn’t want to own one.” It would be fun for maybe 5 minutes. Kinda like chugging a bottle of Champagne instead of beer.
    Now if I owned my own ammo factory, I might feel differently.

  15. avatar MD says:

    The guy sure likes to muzzle himself.

    1. avatar JustAMan says:

      That was the first thing I noticed.

      1. avatar Chrispy says:

        Seriously, it’s a Glock. If you’re going to work on it, field strip it.

        I know it’s cleared and all that, but you can still get slide bite if you slip and it snaps closed on you. Which hurts. A lot.

  16. avatar Anon in CT says:

    I would be a little concerned about the timing – is there any way the striker could fire before the gun was completely in battery? ‘Cause that would suck.

    1. avatar Curtis in IL says:

      The rear end of the barrel drops down when the slide cycles. The primer isn’t lined up with the firing pin until it’s in battery.

    2. avatar Lime Green Medic says:

      @Anon in CT:

      The way it is designed, the “autosear” is a beveled piece of steel which engages the sear. When created, and then installed, this piece of steel is “tuned” so that it only disengages the sear from the striker at the point of lock-up. It cannot do so earlier because of the bevel. Yes, it has to be timed properly but once done, it runs. When the part wears, it disengages the sear later and later (not earlier) until the point where it doesn’t disengage the sear at all, rather than letting it happen out of battery.

  17. avatar Anonymoose says:

    My dream-Glock would be a Glock 41 or 21L with a 9″ barrel in .460 Rowland, one of these conversions, and an ENDO stock adapter.

  18. avatar WuzNtMe says:

    Kind of ironic when he says “nothin’ like celebrating the American 2nd Amendment with full auto”.
    Ya know, ’cause the 2ndA says we should all have these…

    1. avatar Kevin says:

      It doesn’t say we shouldn’t either, Elmer.

    2. avatar Ro Bo says:

      Yeah, seriously right? Kinda like that 1st amendment says nothing about this crazy internet. You know they only had letters on paper then written with a feather dipped in ink. This faster than light email communication shit could’ve never been thought of so we really “shouldn’t” have it. If the pen is mightier than the sword these keyboards are like WMDs!! It must be stopped. People can’t handle this unless they’ve had government training.

  19. avatar Cloudbuster says:

    I’ve always maintained that a fully-automatic weapon is perhaps less dangerous than a semi-auto in a mass shooting. Very few mass shooters have been highly-trained. Most rounds from a fully-auto weapon don’t actually hit anything, or they make redundant hits on the same target, but you do run out of ammunition a whole lot faster.

  20. avatar Larry says:

    Is it illegal to own or purchase the parts just to have incase the zombies attack? You know as a back up plan.

    1. avatar Dale says:

      Sadly, owning a glock and these parts shows intent. Or at least that’s what the ATF claims. They’ve busted folks for owning those pistol stocks and the pistols together, even though they were disassembled. They said it shows intent. Same thing with owning baffles and a threaded tube that they could go into. Not a good idea just to have them, IMO.

      1. avatar LarryinTX says:

        I’m pretty sure possession of ATF credentials proves intent, as well.

    2. avatar pod says:

      They’ll nail you on constructive possession.

  21. avatar Accur81 says:

    The adaptability and reliability of the Glock platform shoes itself again. From the pattern of the ejected brass, I’d guess that this is a G23 with a 9mm conversion barrel and a .40 cal weight spring. I have a similar setup in one of my G23’s. Looks like an absolute blast.

    1. avatar little horn says:

      lol so you think this is the only gun capable of this? surely not.

  22. avatar Connell says:

    Great video – one thing I would have liked to see is some burst fire to show that you don’t have to run the entire magazine out with this conversion kit. Thanks for the show!

  23. avatar Nakia lee says:

    Do you sell this kit?

  24. avatar SkankHunt42 says:

    My penis gets fully erect reading these comments – can anyone recommend a good shemale/tranny site that’s good for spanking to?
    I’m hi on Vicodin and love jerking off.

  25. avatar Enduro Rush says:

    Thanks for any other informative web site. Where else
    may just I get that kind of information written in such an ideal method?
    I’ve a challenge that I’m simply now running on, and I’ve been at the
    look out for such info.

  26. avatar little horn says:

    why is this on here? are you INTENTIONALLY being negligent????

  27. avatar Rusty Williams says:

    Why was this posted? The video no longer exists.
