what do u use as the spent case ejector? iam trying to understand the mechanics behind ejecting out the shell b4 loading the next round. From what ive read im thinking thats the bolt has some kind of hooking piece attached that grabs the casing by the rim and during blow back (or by pulling back) it hits a tapered protrusion attached to the inside of the barrel causing it to flip out...am i close?
@adonovan702 There is no extractor hook. Since it is blowback, the blowback pressure keeps the empty shell pressed against the bolt as the bolt moves back. Then there is the tip of the recoil spring guide rod that pokes through a hole on one side of the bolt face when the bolt is all the way back... the edge of the empty case hits that, and the case is flipped out of the gun.
@Fuzzybeanerizer aahhh now, can you instead weld a lil piece of protrusion to like the bottom of the receiver (i think thats what its called, no?) so while its moving back the shell hits the shit and flips out the ejector port ontop??
@adonovan702 Yes, you could do that instead. I went with the guide rod tip partly because it was easier for me to drill a hole than to mill a deep slot, and partly because I needed a spring guide rod anyway so no extra parts were needed.
@Fuzzybeanerizer you are right now that i think about it, it would be easier to make the guide rod act as ejector...do u know of any web sites i can go to for learning the basics? Im really wanting to make something small but semi, or fully maybe even .22 fully auto but idealy something stronger 32 or maybe even 9mm
@soixe1997 Yes, it is legal to make for your own use under federal law. You may have to meet some state requirements for owning pistols in general, however, depending on your state.
just wondering, how heavy is the bolt itself? did you calculate the weight of it with the whole bolt thrust thing or did you just make something? i've seen a guy who made an open bolt .22lr but his bolt doesnt move back after firing, think it was 160 grams or something.
@redneck500 If you mean functionally, it is a type of gun where the bolt is in the open position when the trigger is pulled and it slams shut after you pull the trigger. Usually the firing pin is just a fixed bump on the bolt face, making for a very simple mechanism. The open-bolt system is typically used for sub-machine guns, so many people thought it is illegal to build or have any open-bolt gun at all, and that is why I wanted to build one... to show that they are legal.
@redneck500 Well yes... lots of people ask me about "converting" this gun to full auto, but that misses the point completely. I designed it to be hard to convert. To try to convert it would be harder than starting from scratch for me. But the knowledge and experience I gained from building it can't be banned.
@M1911A1 Thanks. No, open-bolt guns themselves are not banned. I don't think Congress ever specifically mentioned that feature in any legislation. What would be trouble is if they are easily convertable to full auto... typically that would mean a semi-auto with a magazine that operated on the open-bolt system. Blocked magazine wells that could be re-opened would be bad too. Basically stay away from semi-auto guns based on full-auto designs, and anything with a magazine.
nice gun now you just need a way to make it work with a magazine and your set! ^ btw: have you ever slammed your finger shut when reloading? it looks like it can slash off your thumb
@bazengao I've never been pinched... I guess it could be painful but the bolt is too light to cause any real injury. I'd be more worried about accidental firing in such a case, but the gun does not have a hair trigger or anything so it's not likely to release unexpectedly.
@mp40elite Yes, I did make it. I'm not a licensed manufacturer, but if I was (and had better machinery) I'd still have to charge at least $500 for this gun and nobody with any sense would buy one. I mean, it is a great project to build yourself, but more of a novelty than a practical pistol.
@etucker5007 Well I built 2 of these at once and I think the total cost in materials and cutter wear was probably not more than $50 each including the barrel blanks and all fixturing. But if I was making any product to sell I'd have to charge about $60 an hour shop time just to avoid screwing myself. Then for guns I'd need a manufacturers FFL, the fees for which are significant unless you are making 10,000 guns a year or something. Guns are potentially dangerous so I'd need liability insurance.
I understand where you are coming from. Getting an FLL is a huge pain. But taxes on a type 7 FLL are only about $100 per year or so, + a one time tax when you make each gun. The law only holds you liable if someone is injured because of a manufacturing defect. If someone is injured because of the owner's carelessness the law says you are not liable.
But, I understand, it's a big commitment. I just think it would be neat to make a living doing something you enjoy.
@etucker5007 Well I guess you are right that the FFL fee is not as high as I thought... I must have been thinking of some bill that never passed congress or something; I thought it was at least $300 a year now. But do you know anything about the ITAR registration fee, supposedly $1750 a year even for common gunsmiths, if they work on semi-automatic firearms? Apparently all semi-autos are deemed "defense articles" and therefore gunsmithing is deemed a "defense service."
@etucker5007 Well this ITAR registration fee I'm talking about is through the Department of State, nothing to do with usual ATF stuff on full autos and so forth. Everybody seems confused just what the requirements are, but generally it seems even if you make peripheral parts for guns such as target triggers or recoil pads, never touch an actual gun, you owe the DOS $2250 every single year. The Bush administration increased the fee from $1750 in 2008 before he left office so we can't blame Obama.
@etucker5007 This has to do with international treaties controlling trade in military equipment I guess, and possibly "homeland secuirity." Supposedly aimed at exporters of military equipment, it appears all gun-related manufacturers must pay the basic fee whether they export or not. Anyone offering "defense services," which are defined in such a way as to include all commercial gunsmiths, also has to pay this same fee too, even if they never actually manufacture a thing.
Gosh, what a bummer. All it does is hurt the economy and make life miserable for guys like us. Do you know if this fee also required for unlicensed persons? For instance if someone wanted to make and sell gun stocks or magazines, but no firearms or receivers.
@etucker5007 Yes, from what I've read, those unlicensed business persons do need to pay the ITAR registration fee. There is a lot of confusion and lots of manufacturers of that sort are not paying the fee, but apparently a number of them have been contacted and told to pay it or else. This seems like the opposite of a "loophole" to me... probably it was not even planned or hoped that ITAR would sweep in such innocent businesses so broadly, but that's what the law says so here we go.
It's sounds like the State department has incredible latitude to determine who needs to pay the tax. I read that makers of anti-virus software also have to pay. ITAR looks like a backdoor blanket tax and anyone who manufactures anything weapon or technology related has to pay the tax. It's ridiculous, this law should be changed. Or the "fees" reduced.
@etucker5007 The fee is outrageous for businesses having no intention to export anything to begin with. What are the costs that justify that fee? And even if there were costs that high, there is nothing inherently dangerous to either national security or world peace about making accessories for sporting guns. If there is any "need" for tracking such businesses, then the cost ought to be paid out of general tax revenues. We don't make companies manufacturing box cutters pay for airport security.
True, requiring compliance itself is ridiculous for civilian FFLs and gunsmiths, let alone companies that make accessories. Its a huge obstacle to starting a new business. The fee is just plain nuts, just another reason for the government to take more of your money.
@ExoticSpotting As you probably know, there has never been a law passed against open bolt firearms specifically. Most of the open bolt guns that were once sold as ordinary firearms were actually built from SMG parts, or modelled closely after SMG designs. Or at least they had magazines. So they were easy to convert to full automatics.
I suppose this gun is "possible" to convert, but you'd need machining skills which raise the question if you wanted to break the law why wouldn't you just build a full automatic designed to be full automatic in the first place. I believe the ATF guys recognize they have better things to do with their time than make themselves look silly in court by hassling me about this gun.
@ExoticSpotting Last time i checked 1 shot pistols are considered out-dated by US federal law.. open bolt automatic and open bolt semi are illegal though, if i remember right. Not idea what is different about open bolt anyway
With a closed bolt you pull the trigger and a series of mechanical actions set off the firing pin/hammer. With an open bolt the bolt is held to the rear of the gun (which means you don't have to charge it when you insert a magazine) and pulling the trigger releases the bolt. As the bolt travels forward it strips a round from the magazine and fires it (the firing pin is fixed in the middle of the bolt).
Open bolts are cheaper and sometimes more reliable than closed-bolts (fewer moving parts). But because they are so simple, it's much easier to convert them to full auto. Because the language in the NFA classifies firearms 'readily convertable' into machineguns to BE machineguns, the ATF essentially banned their manufacture in 1982.
@ExoticSpotting Ahh. Thats handy to know. Thanks. I will add it to my permanent memory bank of useless trivia.. i live in the UK afterall, the laws are summed up by saying "throat throttling restrictiveness". Only lever actions bolt actions and various shotguns allowed around here lol, the impact would be amazing if someone did a khyber on a borrowed ak47. The hippies would shit themselves wondering about the "good old days" where everyone was allowed to buy weaponry of all sorts
Just a question, I've always heard that handguns are completely banned in the U.K, but I was wondering, are there are any exceptions, like revolvers or target pistols? Or is it a blanket ban on anything without a shoulder stock?
@ExoticSpotting Blanket ban. They first started making it compulsive for people to register the pistols that they own so the government knew who owned what. Those who didnt hand their handguns/revolvers in by a certain time were nailed and jailed by government controlled agencies when it begun. The government marketed their campaign as if it would make the UK a safer society. Of course we all know thats bs. Nowadays you can recieve 10 years minimum in jail for owning anything close to a handgun.
10 years?! Thats the jail sentence you get in the U.S. if you're caught with a howitzer!
I can't imagine how they could make a case that a .22 target pistol is a 'threatning weapon of war.' And I thought that the idea of a ban on AR-15's was crazy...
@ExoticSpotting Lol.. its the government, all the government. This is what YOU will get if you let the US government trick you like we did.
When the pistols were threatened a ban, the rifle owners never bothered to help them, because they were not the rifles. When the rifle owners were banned, the collectors never helped them because they were not the rifles.
The vicious cycle continued until nothing was left. With the NRA in the USA this traditional process is much slower.
I think we're already headed down that road, years ago when Obama was just a andidate for senator he said he would support a ban on the manufacture of handguns for the civilian market.
If a ban like that did go through, and there was a grandfathering of old hanguns, we would see price spikes like we had with pre-'86 machine guns.
Picture a Glock 17 going for $6,000 at auction. (shudders)
@ExoticSpotting thats why we keep our howitzer in our garage in germany.its non working but they gave us time to get it out of the states or my dad wouldve gotten 16 years in the pen.

@camarokillsstang3 LOL- Automatics are NOT ILLEGAL My friend... The Anti-Gun People managed to reach even you huh? How could you be soo wrong? You can own a Silencer too and thats Legal as well. Its all about TAX STAMP and Paperwork my friend.
@855h0le ok if you can purchase an automatic rifle do it then call the police and tell them you have it and see how much time it takes before they bust down your door.and silencers are illegal you fucking retard and if they were legal then why cant you get them in a licensed gun store?the same goes with automatic weapons you dumbass
@camarokillsstang3 Your a MORON- I say that cause I will PROVE IT! If you ONLY got the facts FIRST- then you'd be SHUTTING the HELL UP ! I will be back with information to do that- SHUT YOU UP!
@camarokillsstang3 Silencers are legal in the USA as there are no federal laws that prohibit civilian silencer ownership. No license or permit is required, just the tax stamp. The ATF has to authorize transfer of the silencer on an ATF from 4 if you buy one, or an ATF from 1 if you make one. 35 states allow civilian silencer ownership. Gun control laws vary from state to state.
@ExoticSpotting Listen- NOTHING is "ILLEGAL" about guns- Maybe "Restricted" is all but NOT illegal. You can own Silencers LEGALLY. I will link you to the ATF website for the FORMS! You can own FULLY-AUTO and open Bolts too!- There ARE restrictions but NOT illegal! You CAN own HAND GRENADES too-! you need ATF Forms to do so!! I KNOW WHAT Im talking about! I'll Link you , just ASK!
As the bolt moves back, the tip of the recoil spring rod pokes out of a hole in the bolt face near the right edge of the case head, and that kicks the case out to the left. There is no extractor, but gas pressure and the deceleration of the bolt due to the recoil spring seem to keep the case in the proper position to hit the ejector reliably every time.
It took me about 2 months to build two pistols in my spare time, to the point you see in the video. I spent a couple more weeks later, re-doing some trigger parts for a lighter pull.
Unfortunately it is nearly impossible to build a fully automatic firearm legally, unless you have a government contract in hand before starting. But I intentionally made this gun as difficult as possible to convert. If I was interested in having an illegal firearm I would have designed it entirely different from the start, to optimize it for full auto use. It irritates me a bit to have talk about supposed ease of conversion keep popping up again and again. Convert it???? I DESIGNED AND BUILT IT.
Congress has never passed a law against open bolt guns. Whether the ATF guys decide to come after you depends on how easy they think it would be to convert to fully automatic, or how much they think they can frighten a jury with it by waving it around in the courtroom. Anything built of surplus military full-auto parts would be very risky, in my opinion. Having an aggressive military type appearance, a dummy magazine well, or including even one surplus SMG part would all be risk factors.
thank you for your answer, by using a full auto trigger group i meant not having it hold back the bolt after your done shooting to make it simpler to manufacture(because i have no clue on how open bolt semi auto works) and not using any military surplus parts
In that case I think you would probably be OK if it was a rimfire and generally difficult to convert. The ATF guys probably look harder at 9mm's and other centerfires.
Thanks. I think it took me about 3 months to design and build 2 pistols to the point where they were shooting for the videos. Then maybe another couple weeks to re-make some trigger parts for a better pull. I bought a pre-rifled rifle-length barrel blank, which I cut in 2 pieces to build two pistols.
i can imagine this being hard to shoot accuratley with the open bolt but if you made a small carbine style target rifle and balanced it well it could be a good little system. test your mite at making a stock and a free floating barrell. get some dovetails cut and put a scope on it
The gun has 2 springs, a bolt or recoil spring and a trigger/sear spring. Both springs were made from a coil spring assortment kit I bought from Brownells (the gunsmithing supplier). They came in long lengths, and I cut them to size.
absolutely wonderful piece of work FB!! I think it's funny how people think you faked it! haha either way I just got a mill and your design has inspired me quite a bit thanks again!!
Good question, but a bit hard to explain. The sear has an oval hole where the sear pin goes through. The sear/trigger pin pushes the sear back, but the more powerful recoil spring forces it forward when the bolt is hooked on it. Once the bolt is released, then the weaker trigger/sear spring gets its way and the sear moves back out of reach of the trigger and can reset.
The main point is just to make a pistol that combines reasonable convenience of operation with maximum simplicity. The other reason is just to prove that there is no law against building one, as many people suppose. I definitely DO NOT intend this to be the start of a full-auto design. I took great pains to prevent this being easily convertible to full auto. It would be far easier to start from raw materials and build something designed from the ground up for full auto, than to convert this gun.
Actually it is numbered, and registered with the local sheriff in accordance with Michigan law. The easy disassembly is for cleaning... I can't see how it would make disposal any easier.
Its easier to dispose of/destroy pieces then one intact piece. I suppose you did havet numbered and registered but seeing as how you are making your own then there isnt much preventing a person from nor numbering ans registering a home made weapon, should they choose not to. After all, who would know?
The answer to the first question is, I did not want to go to prison for building something too close mechanically to a sub-machine gun. The answer to the second question is, by making the bolt as light as possible and the rest of the pistol as heavy as is reasonable, the accuracy problems due to the pre-ignition "jump" associated with open-bolt firing are minimized.
The re-cocking was no problem. The bolt probably comes back with extra force, but the parts that impact are hardened steel so no damage is done. The main problem I had was the trigger pull was about 30 pounds at first. I had to completely remake the bolt, the sear and the safety to get it down to a bearable level.
There is a hole going through the bolt lengthwise, and with the bolt fully to the rear the tip of the spring guide rod (for the recoil spring) pokes through the hole to act as an ejector. Of course there is no extractor needed to pull the case back, since it is the pressure in the case that pushes the bolt back in the first place.
Thanks. This one will shoot less than 2" groups at 25 yards. I have another with a scope that will shoot about 3" groups at 50 yards. I'm embarrassed to admit it, but these only shoot .22 Shorts, not the Long Rifle cartridge. It was part of my redundant strategy to avoid accusations of building a sub-machine gun. I figured the prosecutors would look pretty damn foolish spending tax money to chase after a guy for building a .22 Short target pistol.
That's a lot better than any of my things will group. How long did it take for you to build it? Isn't there some way that you can register the gun to make it legal?
It is legal as a pistol, and registered as such with the state police according to my state laws. Except for very special circumstances, such as doing R&D for potential military use, there is no legal way to build a fully automatic gun -- that's what I was being careful to avoid. I guess the total time, from beginning the planning through remaking many of the parts for better performance to finishing two complete pistols... It was about four months.
Hey Kevin, you're into hunting, right? Why would you NOT want a gun you built yourself, of any type? This pistol shoots well enough when I actually aim it that I plan to use it for hunting ruffed grouse sometime. But mostly it was just fun to build, and it's always fun to show off to people.
The open bolt part was a technical challenge to see how simple the gun could be, and to find out how accurate an open-bolt pistol could be. It's sort of a political statement too, like I'm the only person that dares to do this, even though it is not illegal. Everybody else has kids etc. and doesn't want to stick their neck out and be accused of building a machine gun, but if nobody dares do anything the walls are just going to keep moving in on us.
I know what you mean , I grew up in a small town in the midwest, where at the age of 15 ( maybe younger ) we would take our BB guns or our squirrel gun ( unloaded ) and ride thru the streets on our bicycles and goto the woods, and go hunting or shooting, try that today where i live now, and I'd get locked up. (on a summer day it would be our fishing poles)
our rights of sportmans hunting and defense and been terribly erroded in many parts of the USA
I have got to get me one of those! Quick, patent it so you can sell it. How did you build it? Where did you get the barrel? Where did you get the other parts? Can I have one?
Well thanks. I don't know if there is anything patentable about it, actually. I'm not a licensed manufacturer, so I can't make them for anybody else. Some day when I have time I might draw up better prints and write a plan book or something, probably including additional designs. The barrel for this was a rifle barrel I bought off eBay last year. I cut it in half and made 2 pistols. Probably you can't get barrels on eBay anymore, which makes us all so much safer. I made the other parts myself.
There has never been a law passed by Congress making open bolt firearms illegal. It is true that the ATF guys will go after most open bolt firearms as illegal weapons, but that is because most open bolt firearms ever produced were based on fully automatic guns to begin with and hence are very easily restored to full automatic configuration. My pistol is a new design, has no origin in fully automatic firearms, and indeed was purposely calculated to be almost impossible to convert to full auto.
There is a fixed firing pin, projecting from the bolt face. When the bolt slams shut, it fires the round and re-cocks the bolt to the rear position. The cartridge rim gets crushed between the firing pin ad the chamber face, as the bolt slams fully closed.
Technically it seems very similar to IMI's Uzi series. It also idles with an open chamber and fires the same way. When you could make a mag under it, you'll have a submachine gun with a more than decent ROF.
I'm also planning to make my own series of guns, but i'm still collecting the machinery (not to mention i also have to age before i can start...)
Yes it falls in the same open-bolt class of operation as most sub-machine guns, but I purposely (for legal reasons) made it almost impossible to convert to fully automatic. The bolt is just a big cylinder shape at the front, with no clearance cuts for magazine feed lips, the trigger is located where the magazine would go, etc. It would be way easier to just build a sub-machine gun from scratch to a proper design than to convert this in some improvised fashion, in case anybody is wondering.

@Fuzzybeanerizer
You'd be surprised at how much cheaper it is to make stuff when you plan to make more than 1.
I machined an ar-15 receiver, cost me about $200 . But Since I now have all the tools I need, I could make another one for about $30.
You can also make jigs for a milling machine so you can reduce setup time.

Yeah, you have to pay extra taxes if you deal with NFA items.
I find it interesting that the only qualification you need to deal in machine guns is to pay more taxes.
Especially when the anti-gun folks are always harping about the need to to be "specially trained."
haha, thats a little off topic though

@etucker5007 This has to do with international treaties controlling trade in military equipment I guess, and possibly "homeland secuirity." Supposedly aimed at exporters of military equipment, it appears all gun-related manufacturers must pay the basic fee whether they export or not. Anyone offering "defense services," which are defined in such a way as to include all commercial gunsmiths, also has to pay this same fee too, even if they never actually manufacture a thing.
Fuzzybeanerizer 1 year ago
@Fuzzybeanerizer
Gosh, what a bummer. All it does is hurt the economy and make life miserable for guys like us. Do you know if this fee also required for unlicensed persons? For instance if someone wanted to make and sell gun stocks or magazines, but no firearms or receivers.
etucker5007 1 year ago
@etucker5007 Yes, from what I've read, those unlicensed business persons do need to pay the ITAR registration fee. There is a lot of confusion and lots of manufacturers of that sort are not paying the fee, but apparently a number of them have been contacted and told to pay it or else. This seems like the opposite of a "loophole" to me... probably it was not even planned or hoped that ITAR would sweep in such innocent businesses so broadly, but that's what the law says so here we go.
Fuzzybeanerizer 1 year ago
@Fuzzybeanerizer
It's sounds like the State department has incredible latitude to determine who needs to pay the tax. I read that makers of anti-virus software also have to pay. ITAR looks like a backdoor blanket tax and anyone who manufactures anything weapon or technology related has to pay the tax. It's ridiculous, this law should be changed. Or the "fees" reduced.
I am amazed at how abusive the Feds have become.
etucker5007 1 year ago
@etucker5007 The fee is outrageous for businesses having no intention to export anything to begin with. What are the costs that justify that fee? And even if there were costs that high, there is nothing inherently dangerous to either national security or world peace about making accessories for sporting guns. If there is any "need" for tracking such businesses, then the cost ought to be paid out of general tax revenues. We don't make companies manufacturing box cutters pay for airport security.
Fuzzybeanerizer 1 year ago
@Fuzzybeanerizer
True, requiring compliance itself is ridiculous for civilian FFLs and gunsmiths, let alone companies that make accessories. Its a huge obstacle to starting a new business. The fee is just plain nuts, just another reason for the government to take more of your money.

@ExoticSpotting As you probably know, there has never been a law passed against open bolt firearms specifically. Most of the open bolt guns that were once sold as ordinary firearms were actually built from SMG parts, or modelled closely after SMG designs. Or at least they had magazines. So they were easy to convert to full automatics.
Fuzzybeanerizer 1 year ago
I suppose this gun is "possible" to convert, but you'd need machining skills which raise the question if you wanted to break the law why wouldn't you just build a full automatic designed to be full automatic in the first place. I believe the ATF guys recognize they have better things to do with their time than make themselves look silly in court by hassling me about this gun.

Pawnbroker00 1 year ago
With a closed bolt you pull the trigger and a series of mechanical actions set off the firing pin/hammer. With an open bolt the bolt is held to the rear of the gun (which means you don't have to charge it when you insert a magazine) and pulling the trigger releases the bolt. As the bolt travels forward it strips a round from the magazine and fires it (the firing pin is fixed in the middle of the bolt).
ExoticSpotting 1 year ago
Open bolts are cheaper and sometimes more reliable than closed-bolts (fewer moving parts). But because they are so simple, it's much easier to convert them to full auto. Because the language in the NFA classifies firearms 'readily convertable' into machineguns to BE machineguns, the ATF essentially banned their manufacture in 1982.
ExoticSpotting 1 year ago
@ExoticSpotting Ahh. Thats handy to know. Thanks. I will add it to my permanent memory bank of useless trivia.. i live in the UK afterall, the laws are summed up by saying "throat throttling restrictiveness".

Just a question, I've always heard that handguns are completely banned in the U.K, but I was wondering, are there are any exceptions, like revolvers or target pistols? Or is it a blanket ban on anything without a shoulder stock?
ExoticSpotting 1 year ago
@ExoticSpotting Blanket ban. They first started making it compulsive for people to register the pistols that they own so the government knew who owned what. Those who didnt hand their handguns/revolvers in by a certain time were nailed and jailed by government controlled agencies when it begun. The government marketed their campaign as if it would make the UK a safer society. Of course we all know thats bs. Nowadays you can recieve 10 years minimum in jail for owning anything close to a handgun.
Pawnbroker00 1 year ago
10 years?! Thats the jail sentence you get in the U.S. if you're caught with a howitzer!
I can't imagine how they could make a case that a .22 target pistol is a 'threatning weapon of war.' And I thought that the idea of a ban on AR-15's was crazy...
ExoticSpotting 1 year ago
@ExoticSpotting Lol.. its the government, all the government. This is what YOU will get if you let the US government trick you like we did.
When the pistols were threatened a ban, the rifle owners never bothered to help them, because they were not the rifles. When the rifle owners were banned, the collectors never helped them because they were not the rifles.
The vicious cycle continued until nothing was left. With the NRA in the USA this traditional process is much slower.
Pawnbroker00 1 year ago
I think we're already headed down that road, years ago when Obama was just a andidate for senator he said he would support a ban on the manufacture of handguns for the civilian market.
If a ban like that did go through, and there was a grandfathering of old hanguns, we would see price spikes like we had with pre-'86 machine guns.
Picture a Glock 17 going for $6,000 at auction. (shudders)

@camarokillsstang3 Silencers are legal in the USA as there are no federal laws that prohibit civilian silencer ownership. No license or permit is required, just the tax stamp. The ATF has to authorize transfer of the silencer on an ATF from 4 if you buy one, or an ATF from 1 if you make one. 35 states allow civilian silencer ownership. Gun control laws vary from state to state.

how did you get it to eject?
tmoney818 2 years ago
As the bolt moves back, the tip of the recoil spring rod pokes out of a hole in the bolt face near the right edge of the case head, and that kicks the case out to the left. There is no extractor, but gas pressure and the deceleration of the bolt due to the recoil spring seem to keep the case in the proper position to hit the ejector reliably every time.

Unfortunately it is nearly impossible to build a fully automatic firearm legally, unless you have a government contract in hand before starting. But I intentionally made this gun as difficult as possible to convert. If I was interested in having an illegal firearm I would have designed it entirely different from the start, to optimize it for full auto use. It irritates me a bit to have talk about supposed ease of conversion keep popping up again and again. Convert it???? I DESIGNED AND BUILT IT.

are open bolt single shots like this still legal to manufacture or are they considered machineguns?

rofllolcake 2 years ago
Congress has never passed a law against open bolt guns. Whether the ATF guys decide to come after you depends on how easy they think it would be to convert to fully automatic, or how much they think they can frighten a jury with it by waving it around in the courtroom. Anything built of surplus military full-auto parts would be very risky, in my opinion. Having an aggressive military type appearance, a dummy magazine well, or including even one surplus SMG part would all be risk factors.
Fuzzybeanerizer 2 years ago
thank you for your answer, by using a full auto trigger group i meant not having it hold back the bolt after your done shooting to make it simpler to manufacture(because i have no clue on how open bolt semi auto works) and not using any military surplus parts

In that case I think you would probably be OK if it was a rimfire and generally difficult to convert. The ATF guys probably look harder at 9mm's and other centerfires.

The gun has 2 springs, a bolt or recoil spring and a trigger/sear spring. Both springs were made from a coil spring assortment kit I bought from Brownells (the gunsmithing supplier). They came in long lengths, and I cut them to size.

what do you use to keep the bolt from slamming closed again after the cartridge is fired, before you are able to let go of the trigger?
dudeonajoescup 2 years ago
Good question, but a bit hard to explain. The sear has an oval hole where the sear pin goes through. The sear/trigger pin pushes the sear back, but the more powerful recoil spring forces it forward when the bolt is hooked on it. Once the bolt is released, then the weaker trigger/sear spring gets its way and the sear moves back out of reach of the trigger and can reset.

What's the point of an open bolt single shot? Do you intend it to be the start of a full-auto design?
GetMeThere1 3 years ago
The main point is just to make a pistol that combines reasonable convenience of operation with maximum simplicity. The other reason is just to prove that there is no law against building one, as many people suppose. I definitely DO NOT intend this to be the start of a full-auto design. I took great pains to prevent this being easily convertible to full auto. It would be far easier to start from raw materials and build something designed from the ground up for full auto, than to convert this gun.

It's interesting that this is FAR faster shooting than a typical "zip gun" or homemade design--specifically because of the open bolt funtioning.

The answer to the first question is, I did not want to go to prison for building something too close mechanically to a sub-machine gun.

Spinnygrass 3 years ago
The re-cocking was no problem. The bolt probably comes back with extra force, but the parts that impact are hardened steel so no damage is done. The main problem I had was the trigger pull was about 30 pounds at first. I had to completely remake the bolt, the sear and the safety to get it down to a bearable level.
Fuzzybeanerizer 3 years ago
Did you use an ejector from a .22 pistol/rifle or did you make it auto-eject with some other means?
GCMxVeGeTa 3 years ago
There is a hole going through the bolt lengthwise, and with the bolt fully to the rear the tip of the spring guide rod (for the recoil spring) pokes through the hole to act as an ejector. Of course there is no extractor needed to pull the case back, since it is the pressure in the case that pushes the bolt back in the first place.
Fuzzybeanerizer 3 years ago
nice, but since it pulls back from the pressure build up this means that your bullet looses power.
but excellent build. if you can open it on the top you could probobly add a magazine so that you dont need to reload manualy.
also did you need to carve out those lines for the bullet to spin? and do you have anything on the "how to make" id love to make one. thanks

It is legal as a pistol, and registered as such with the state police according to my state laws. Except for very special circumstances, such as doing R&D for potential military use, there is no legal way to build a fully automatic gun -- that's what I was being careful to avoid. I guess the total time, from beginning the planning through remaking many of the parts for better performance to finishing two complete pistols... It was about four months.

The open bolt part was a technical challenge to see how simple the gun could be, and to find out how accurate an open-bolt pistol could be.

There has never been a law passed by Congress making open bolt firearms illegal. It is true that the ATF guys will go after most open bolt firearms as illegal weapons, but that is because most open bolt firearms ever produced were based on fully automatic guns to begin with and hence are very easily restored to full automatic configuration. My pistol is a new design, has no origin in fully automatic firearms, and indeed was purposely calculated to be almost impossible to convert to full auto.

Reevesy1989 4 years ago
There is a fixed firing pin, projecting from the bolt face. When the bolt slams shut, it fires the round and re-cocks the bolt to the rear position. The cartridge rim gets crushed between the firing pin ad the chamber face, as the bolt slams fully closed.
Fuzzybeanerizer 4 years ago
The bolt moves extremely fast, so its motion might not be evident in the video.
Fuzzybeanerizer 4 years ago
Technically it seems very similar to IMI's Uzi series. It also idles with an open chamber and fires the same way. When you could make a mag under it, you'll have a submachine gun with a more than decent ROF.
I'm also planning to make my own series of guns, but i'm still collecting the machinery (not to mention i also have to age before i can start...)
nst6ldr 4 years ago
Yes it falls in the same open-bolt class of operation as most sub-machine guns, but I purposely (for legal reasons) made it almost impossible to convert to fully automatic. The bolt is just a big cylinder shape at the front, with no clearance cuts for magazine feed lips, the trigger is located where the magazine would go, etc. It would be way easier to just build a sub-machine gun from scratch to a proper design than to convert this in some improvised fashion, in case anybody is wondering.
