Automatic zip gun (homemade)- final version

[masonnf1]

I've made 3 guns before, all single-shot. two of them were .22's and the third is a .410 handgun. I plan to make a full auto next with your video as a base. I will probably make it 9mm.

[Eatherbreather]

What I've always wanted to know is, what, if anything can be done to slow the rate of fire down to a more manageable rate. Is it stiffer or lighter recoil springs? Heavier/lighter bolts? Longer bolt travels or what? Does using lower velocity ammo help? What about blanks?Any and all ideas welcomed.

[retrokinetik76]

Only if he had a lathe and milling machine

[Nitricthunder]

Impressive

[akompsupport]

outstanding work. Thanks for posting this informative video!

[notanotherCoDfan]

what brand of mags are you using?

[Wrestlerdude126]

Love it can u show how 2 make it w house held items

[JohnWelsch]

Where do I find plans, ratios, and other information?

[penguin99ify]

I made two of these in the late 70's, one in 9mm and one in .22 cal. The 9mm was easier to build and more reliable because STEN mags were plentiful and cheap. The .22 cal was finicky and I was unable to find a suitable mag (without having feed problems). The latter gun had a square bolt with a upside down "U" shaped recess on the face and grooved underside to catch the round without touching the mag lips. ROF was estimated at 1,000 to 1,100 RPM. The video brought back fond memories...thanks.

[terminator0405]

To make an ejection system do you need any extractors? Ive seen other videos of people who used the force of the case coming back to pull it out of the chamber, would that work?

[jstefa2]

@terminator0405 short answer... yes :)

[royrubio07]

You should do one built around a remmington .22 50 round clip I wanna if it can be done or if the clip will break cuz they're plastic, I've yet to find a metal one.

[Ki113r210]

@giftedkidrules well yes of a sort. the thing is with even most machine pistols, you either have enough ammo, or a slow enough rate a fire, that you can fire multiple bursts. this thing, with only a 10 round magazine, and such a high rof, i dont think youd get any more than one burst per mag XD very neat little gun, shame its illegal around here

[pombos007]

why doesnt te cartidge ignite when its hitted by the bolt in the magasine?

[Ki113r210]

@pombos007 because it has room to move foreward, to less pressure is put on the rim. when the round is chambered though, the bolt hits it and all the force is applied to the rim, so it fires off. this is why your not likely to set off a .22 by dropping it, but if you lay it on something hard and smash it with a hammer, it probley will

[thegreatcornholyio]

why does everyone making these vids where gloves?

[Ki113r210]

something im wondering is, wouldnt the rifled barrel cost quite abit?

[TheCorx3044]

can u do a larger mag so u can shoot more at one time?

[gregry111]

i'm sure this gun will work but parts of the video are almost impossible to read

[Ki113r210]

this thing deserves its own firing class... like "single shot auto burst" handgun. ya get one shot, one pull of the trigger per reload, and it dumps the whole mag in a fraction of a second. very cool

[theawesomemile]

no button where it says skip to blah blah well then im going to make one skip to 7:55

[Ki113r210]

awesome stuff man. this makes me want to pick back up on my designs for a lever action 12 gauge..

[n1663r]

the budget for the animention exceeded that of both Avatar and Titanic combined!

[oj3000harris]

a umm cant u make a zip gun out of pen

[lbgundead]

very creative!

[dethtotheking]

Nice build! make one thats pretty lol

[Butchymartin]

Fucking awesome

[smokestakz]

and you can register this as a AOW....have to get it done thru a c3 dealer and its expensive as shit...just buy a regular 22 of some sort..

[smokestakz]

all this for a funky lookin zip that will have a bail of issues.....not gonna cancel my order on a Ruger Charger (same upper and lower as the original 10/22 but inly has a 10in stock and mini stock...brilliant little design)

[blaketheawesomedude]

Have you considered making a legal gun, you can legally build your own semi auto as long as it is legal to own (ie no rifles with less than 16" barrel or pistols with foregrips, issues with 922 compliance etc) and have something nice to show off, instead of a liability.

[24680kong]

Is there a way to do this legally in the US? Will it require the $200 dollar tax stamp just to make it?

[RoReviews]

Hey , OldDirtyRatbastard , U left out the Spring , which u slapped on it can u make a new video?

[ak47citizensoldier]

are you a licensed class III manufacturer?

[oldstock1607]

AWESIIIIIIIIM.

how many rounds did that fire at the end?

[nkm545]

Молодец, автоматическое оружие сделал, respect

[twonulator]

Excellent work, excellent video. Top notch stuff.

[YungStar490]

i like yours and ill pay you man how much nall let me buy the 1 uue used in the video how much dude

[ETeacherK]

This is experimentation at it's finest! :) I commend you!

Dam, too bad your experiment is illegal here.... cough cough...

[notanotherCoDfan]

Hey can u tell me how you made the trigger? seeing how this worked, i found a out a way to possibly make a .410 shotgun thats semi auto with this design

[EthanJM]

What country are you from? Is it actually legal to make a zip gun? Here in america you are only allowed to make muzzle loaded firearms or cannons, not that it stops people from making anything breach loaded of course.

[belbro62]

wow that is a cool gun.

[TheBlabla1996]

nice, i wish i could do that to

[mccauley404]

5:56 lol ehehe

Your rate of fire is about 1000 rounds/mn, could reduce it with another spring for the bolt. Or better for safety, locked breech. You have the skill to do it. Gas operated firearm just like the AK47 or the M4.

[OldDirtyRatbastard]

@mccauley404 The limitation is with the power of the cartridge. This is the heaviest spring (for 3 cases length recoil) that a .22 will push back reliably, and thus this gun is in the lower end of the possible fire rates.

A locked breech is not supposed to slow down the action, only as you say to provide safety by ensuring that the gases vent fully before cycling. I have a similar auto carbine with a 45cm barrel and no locked breech which works, so it is completely unnecessary here.

[OldDirtyRatbastard]

@mccauley404 I can tell you from testing that the high-velocity 40grs .22s can work in direct blowback with barrels up to 70-80cm, provided that you use a bolt heavy enough. Even then, it never goes under 800 rpm.

[rockergod789]

i could probably make something similar to this, given some time and materials...

[OldDirtyRatbastard]

@rockergod789 Anybody could, that's the point of the video.

[way2easy2love]

great job love the vid!

[TheWarpedminds]

That was sweet

[MrBagginsEsq]

I'd be cautious making a full auto gun. Not that I think if you live in the us you would get into any trouble- legally that is, but I REALLY think you should be careful. I doubt, as some people might say the gun is a danger to HIMSELF, still the government is strangely against guns. I personally see nothing wrong with a full auto weapon. Just be careful!

[OldDirtyRatbastard]

@MrBagginsEsq Oh, thanks for the concern, but i'm not American. Our government doesn't care about that kind of thing, i think 1 in every 2 people i've met have at least a pipe-slam shotgun. As for physical danger, the barrel's rated for 5.56, so a .22 is nothing for it.

[MrBagginsEsq]

@OldDirtyRatbastard Well that maybe but you'd never see me leave this country for any where else. What other country can a broke couple living paycheck to paycheck have two brand new cars in their driveway. Glad my parents stopped doing that YEARS ago. Texas has the best U.S. gunlaws in my opinion. Don't know where you live, but I doubt it's a western country.

[OldDirtyRatbastard]

@MrBagginsEsq Oookay, first off, i don't know in which weird way you interpreted my reply to somehow think i was advising you to leave your country. What i said was that your concern for my getting into legal trouble was unnecessary, nothing more.

Secondly, any country that has a functional banking system will allow a working class family with a somewhat secure income to loan money over a couple of decades to get their brand new cars, and even their home. Which is sad IMO, but is often their...

[MrBagginsEsq]

@OldDirtyRatbastard Hey just a joke. Jeez... And people call me the worse lituralist.

[MrBagginsEsq]

@OldDirtyRatbastard Liked the video by the way.

[OldDirtyRatbastard]

@MrBagginsEsq Well thank you.

[OldDirtyRatbastard]

@MrBagginsEsq only way to access property. Now, how does this relate to gun laws ?

[stein1125]

did you use the trigger setup from home workshop guns for defense and resistance

[OldDirtyRatbastard]

@stein1125 No, i believe his is selective fire.

[Joinville92]

Be careful. Can hurt real bad!

[OldDirtyRatbastard]

@Joinville92 What do you mean ?

[Joinville92]

@OldDirtyRatbastard a friend of myne lost his hand with a zip-gun!!

It blew up in his hand.

[OldDirtyRatbastard]

@Joinville92 Dramatic, but that's what happens when you use a car antenna for a barrel or shit like that.

[MrKreten]

i still dont understand how to make the ejector.....i made a single shot zip gun but that is a pain to reload....i realy want to make a automatic one so can someone please explain me how to make the empty shells fly out...:)

[OldDirtyRatbastard]

@MrKreten The ejector is just a piece of metal sticking out of one of the receiver's sides. It's long enough so that the side of the recoiling casing hits it and gets deflected out of the gun. If yours doesn't work, it may be too long (the casings hit it but don't get deflected) or its shape isn't good.

[MrKreten]

@OldDirtyRatbastard but how can the bolt hit the shell if the ejector is sticking out of the receiver?

[OldDirtyRatbastard]

@MrKreten There is a slot cut in the side of the bolt not to hit the ejector. And the ejector is placed before the point where the round exits the magazine lips, so that it does not hold down the cartridge being chambered.

[MrKreten]

@OldDirtyRatbastard can i send you my "plan" of a automatic gun i want to make??? i think this could work...

[OldDirtyRatbastard]

@MrKreten Sure, put it on imageshack or something and send a link.

[Tomynventor]

i do not understand the trigger system, is it like a normaly zip gun?

[OldDirtyRatbastard]

@Tomynventor Not really. With a zip gun, you push the cocking handle out of a slot with your thumb and it fires. This trigger is rather like that of an smg, where the bolt isn't held by the handle but by a separate trigger+sear, which you press.

[BAYAREA4150]

let me guess your russian

[OldDirtyRatbastard]

@BAYAREA4150 I work there.

[OldDirtyRatbastard]

@OSWALD117 Yep, your sear isn't pressed strongly enough by whatever spring you're using, or it is incorrectly shaped. Make sure that the surface which catches the bolt isn't cut towards the front, or the bolt will easily push the sear down.

[porrsmurfen]

Have you tried firing this with subsonics (short rounds), and if so, did it operate properly?

[OldDirtyRatbastard]

@porrsmurfen If you mean .22 short, they won't work, they don't recoil enough to cycle the action. Regular subsonic .22LR (heavy bullets) work perfectly.

[ELITEHAMSTER123]

@OSWALD117 Sear. It may be too short, and not long enough to catch the bolt when firing, or, you need a better spring to push the sear up.

[AtWarWithGod]

This is nuts!

[laylow132]

very nice n simple

[garfeild500]

that is amazing! good job!:)

[porrsmurfen]

Is there a particular reason why one wouldn't be able to use a double stacked magazine for the same fundamental design, or did it just happen to be more convenient with a single-stacked one for you?

Great video by the way - try drilling a few holes through the end of the barrel to work as a muzzle break, might help to settle that recoil. :)

[OldDirtyRatbastard]

@porrsmurfen If the double stack has a thin enough top, it would actually work without modifications. But you could easily adapt the well to take any kind of magazine. I used a single because this is a cheap and useless little demo gun, it needs no capacity.

As for the recoil, it is controllable as is, the gun moved a lot in the video because i was shooting in an awkward position over the camera. In normal use from the hip or at eye level, even a novice shooter can hit at 30-40m.

[porrsmurfen]

@OldDirtyRatbastard I was mostly thinking in respect to the large variety of magazines available to for instance the ruger 10/22, so that instead of having to stock up on chinese 10 rounders of doubtful quality, one could attach a 100 rd. magazine from a reliable retailer - Although I suppose the 10/22 mag is relatively thick at the top.

[OldDirtyRatbastard]

@porrsmurfen The 10/22 mags are a very poor choice, way too thick, they replace a rotary magazine after all. A suitable 30-rounder is the remington 597 magazine which fits this gun without modifications. Suitable 100 rounders would be the .22 conversion AR drums.

[deadgoodman]

holy shit that is some ugly ass gun!! i love it!

[OldDirtyRatbastard]

@deadgoodman I have an even uglier one in the making, stay tuned.

[falloutshelteradio]

Nice, pretty smart, good work... LOVE IT.

[ELITEHAMSTER123]

"needs a better recoil sheild" I see a lack of one in the first place... Either way, very nice, although you may want to affix stock, either by welding a bent frame stock onto the pistol grip, or on the upper reciver.

[OldDirtyRatbastard]

@ELITEHAMSTER123 By recoil shield i meant what stops the rearwards movement of the bolt, which in this case was a simple screw through the receiver, and it broke, as seen in the video. And, a stock ? For a 3 inch barreled gun ?

[ELITEHAMSTER123]

@OldDirtyRatbastard heck yeah! :D

[OldDirtyRatbastard]

@ELITEHAMSTER123 Haha, and then you're gonna try to rob a bank with it or something XD

[ELITEHAMSTER123]

@OldDirtyRatbastard Hell, the way everyone is anti-gun, I could bring in a nerf gun spray painted... I can see it now...

"OMG he has a gun! And the orange tip is painted OVER! That maniac!"

"Look at the illegal 50 caliber projectiles!" nerf foam tips come around 1/2" ;)

"And look! He has it camoflauged! It lets him perform inhuman reloads and headshots! I know, because I played call of duty"

XD

[MrMorasmus]

Excuse me, do you have all the necessary permits and licenses to produce and posses such a weapon? Because if not you should be hearing from the ATF shortly.

[BIGM420ganja]

@MrMorasmus EXCUSE ME COCKSUCKER , WHO GIVES A FUCK IF HE HAS OR HASENT AHAHAH GOODLUCK TRACKING HIM DOWN BECAUSE U CANT OFF YOUTUBE SIMPLE, UNLESS U GET HES EMAIL WICH U WONT :) soo catch pooof :)

[bf2lover42]

@BIGM420ganja You know YouTube will kindly provide his email, IP address and all of that jazz if they ask.

[OldDirtyRatbastard]

@bf2lover42 But they won't bother with doing that.

[bf2lover42]

@OldDirtyRatbastard of course not. Mr. BIGM420ganja trusts youtube a lot, that's all

[OldDirtyRatbastard]

@BIGM420ganja Indeed, if the authorities want to find me they will, they may legally force youtube to release my IP (that of my proxy), and then get my own IP and from the proxy's owner, and finally my name from my provider.

[OldDirtyRatbastard]

@MrMorasmus I don't, and there is no "ATF" in my country.

[TheTacticalbutterfly]

is it possible to make your model closed bolt

[OldDirtyRatbastard]

@TheTacticalbutterfly Not this particular model. If it is with the purpose of making it a semi, just using a semi trigger will work.

[airsoftnuts1]

Exceptional job! How did you get around firearms manufacturing laws tho?

[OldDirtyRatbastard]

@airsoftnuts1 I didn't, this is at my own legal risk.

[smalltownaffiliated]

where did you get the magazine

[OldDirtyRatbastard]

@smalltownaffiliated Spare magazine from my carbine. You can get those in 5 to 35 rounds in any gun show or armory.

[Tomatoebruce]

Wooooow! awsome work my friend! I always thought it would be impossible to improvise a 22. gun because of the rim cartrige... I once began a 9mm submachinegun in Luty`s design but never finished...

check out my videos ;)

[OldDirtyRatbastard]

@Tomatoebruce Thanks, cool pistol too. And yes, rimfires are a pain, i don't recommend them. But at least you can shoot a ton without remorse.

[MrJmak223]

That is quite impressive, well done on building a working SMG! Do you think an air rifle barrel could work also if it is suiteably thick and chambered properly?

[OldDirtyRatbastard]

@MrJmak223 It would work, but depending on the rifling it may wear quite quickly.

[wsmith68]

that seems like the way the ww2 british stens, brens whatever worked. they were really cheeeep small machine guns

[OldDirtyRatbastard]

@wsmith68 Yeah, the Sten, exact same mechanism but in centerfire, so it was actually even simpler than this. And the Bren is a gas operated .303 machine gun.

[deoss69]

so im woundering why you would need to make one of those its bad ass and i have done the almost the same but why post here

[OldDirtyRatbastard]

@deoss69 Duh, why do people post videos of their computer, guns or cat ? Cause they are proud of them. And in this particular case, to show that building this type of gun is possible for an amateur. You should post a video of yours too, i'm curious now.

[trainspotting187]

Nice work you show us here,

I just have one question for you :

it seems that you have to hold the gun and the magazine but you 'll fix this soon :)

[OldDirtyRatbastard]

@trainspotting187 Thanks, and yes, the magazine holds need to be pressed against the receiver, no tolerance for wobbling. So i was too lazy to add a spring-powered thingy to keep it in place.

[OldDirtyRatbastard]

If you just want to see it shoot, skip to 7:51
