How hard is home making a firearm? Have you tried? And is reloading ammo worth a shot too?
I know what you are
>>64888605>Have you tried?no>And is reloading ammo worth a shot too?sorta
>>64888686It's not illegal to make your own guns as long as you don't sell them.
>>64888686HE'S BRINGING LOVE!BREAK HIS LEGS!
>>64888719>It's not illegal to make your own guns as long as you don't sell them.I'll add to this as some know it all is going to chime in with some bullshit. They have to abide by the ATF rules. No full autos, no SBRs, etc, and you have to be lawfully able to own guns, not a felon, etc.
I want to come up with a design that is as simple as possible. Using a 2x4, less than a foot of galvanized box rail, channel rail, box rail, etc, some lock collars, a Dremel, some kind of barrel material, some kind of homemade bolt which can really be made a million different ways with stacked washers and a stick welder or a torch and some silver solder or whateverLuty's design is aged and you can't find a lot of that shit anymore.
>>64888686not illegal
>>64888605How homemade are we talking?
>>64888825>Hello Blicky
>>64888605>Have you tried?
>>64888724In addition to this, semi-auto open-bolt guns are completely legal in the US (on a federal level) provided that they're originally built as semi-autos.The ATF's kvetching about open-bolt semi-autos is only in reference to guns that were originally designed as full autos. The regulations are about guns that are "easily restored" to full auto fire, not "easily converted".So you're not allowed to build an open-bolt semi-auto STEN gun or MAC-10, since those were originally fully automatic.But the laws and the ATF are fine with randos welding together open-bolt semi-auto pipeguns in their garages, provided that the guns are original creations and not semi-auto derivatives of other designs that were originally designed as machine guns.Fudds trying to claim that all open-bolt semi-autos are B& by the GayTF will sometimes start rambling about the FOX carbines.Those weren't originally designed as machine guns, but the glowies (correctly) classified them as such because those badly made piece of shit guns would (without any modification) fire full auto if the safety and the trigger were manipulated simultaneously.The GayTF classified those as full autos, but it had nothing to do with the open-bolt nature of the guns.
>>64888605I have "made" 10+ firearms. Mostly from parts kits available online. AMA
>>64889056Are the kits cheap and what material are they made from?
>>64889113>are the kits cheapNo. They will always cost more than the last time you looked so you should buy now.>what materials are they made fromParts kits are chopped up surplus firearms. So they are factory original parts usually, just with the receiver gone. It really depends on what kit you're looking at. Go browse apexgunparts.com or any other gun parts website to look at available kits
>>64888605>How hard is home making a firearm? Making something that will shoot one bullet once is incredibly easy. Accuracy, repeating, and reliability all make it a lot harder. The more off-the-shelf parts you use (especially fire control parts and barrels) the easier it gets. But barrelmaking and magazine geometry are always the hardest parts. A simple falling-block .22LR/Magnum survival rifle is an excellent starter project.>Have you tried? Obviously. Until my state effectively outlawed it. Not paying for a literal million-dollar insurance policy and constant police harassment for the "privilege" of operating an FFL.>And is reloading ammo worth a shot too?Depends on what you need and why. Some guns it's essentially required, especially with black powder and antiques. For 12g or 9mm there's really no point at all.
>>64888605>How hard is home making a firearm? Frankly it's not hard at all. Any motivated individual can probably cobble together a functional slam-fire 12GA with pieces of metal you'd find in an ordinary home's basement plumbing.A perfect example of this is the guy who smoked Shinzo Abe in Japan not so long ago - that was just a bunch of scrap metal taped together, and he killed the former leader of a first world nation. If you want to make something BETTER than that, a combination of skill, machinery access, time allotment, and experience will determine your outcome. IE if you've got experience, time, and skill, you can put together a nice, functional example with tools as simple as hand files and drill bits. If you've got machinery, time, and skill you can compensate for needed experience.If you've got machinery, time, and experience, you can develop skill.If you've got machinery, skill, and experience, you can obviously produce great things very rapidly.If you're going to make an attempt to produce decent firearms there's no way around investing in three of those four.>Have you tried?I have a lathe and mill in my garage, as well as the three main types of welders, drill presses, band saws, etc.I previously was employed in industrial service and repair, plus have generations of family involved in trades, so grew up quite handy and spent years of my youth with my grandpa and dad building all kinds of shit, so that's kind of normal in my family.So short answer yes, but mainly I do gunsmithing stuff as a hobby, rebarrelling receivers, modifying existing firearms, etc, and not making things from scratch.
We really need to have a dedicated parts kit general with all the cool new stuff coming in as of late.I’m still seething I missed both z-70b drops. Apex says they’ll be around for a while but I’m fomoing.
does anyone remember that one German guy in 2019 who tried to shoot up a synagogue but couldn't get through the door? The one thing I remember from him was that he had the worst home made guns ever. One of them literally broke during the attack.
>>64888605>And is reloading ammo worth a shot too?Depends on what you're shooting. 12 gauge? Absolutely. 9mm? Not unless you want a hobby/something to do.
>>64888724Some cuck states have restrictions on top of that, Michigan is a faggot state that demands you register homemade guns with the state police. As always anons, don't fall for glowniggers using the glownigger meme to end conversation, use the power of the internet to research your local gun laws to the letter and move without fear.
>>64888605AR's are a cakewalk. I built one AK as well. Need to do another sometime as I have another kit in the attic I never got around to. Also have at least one or two AR pistol kits up there too... Anyone got any cheap places to buy AK flats these days?
>>64889591yes, he built a crappy luty copy that used 9mm loaded with black powder. what a fucking idiot, black powder rarely works in semi autos due to how badly it fouls everything
>>64889591Odds are the problem was his powder, not the guns.
>>64889839Wasn't it a sugar-based homemade propellant, not BP? BP requires a loicence in krautland, and sugar based shit fouls even faster because lmao carmelized crap everywhere.
>>64889591I seem to remember it absolutely smoking some liberal lady
>>64889901I don't think it matters the base of the propellant matters much, it was unregistered homemade propellant in an illegal homebuilt firearm.As an American who could build said items with the proper licenses, that shit wouldn't work beyond a few rounds and illegal explosives would have been a better bet but this guy was a retard and lives were saved because of it. I swear these shooters are so corrupt of mind they are blinded by their own hate, or ego, or pride. at least that helps innocents escape because they're so proud of their actions. Idk I'm fairly inebriated and kinda pissed parts kits don't include the important bits like trunnions anymore for cheap
>>64889936probably could have taken a cheap train to Romania or something and just bought guns
>>64888762>want to come up with a design that is as simple as possible.Then go for a pen gun or a single shot derringer. Punks in the 50s and 60s made zip guns out of scrap steel and wood.
>>648887623/4" pipe fits a 12 gauge shotgun shell quite well...
>>64889992I was thinking more of an open bolt F/A SMG made from common materials. Luty-style lock collar, tubing barrel, and sheet steel feed ramp bolted to a piece of channel steel with a bolt made of stacked washers brazed together with a 3d printed magazine and trigger housing or the lower assembly can be made out of wood with chisels and a drill press.
>>64889998Slam-bang shotguns are a thing. As simple as you can get before you start going for muzzleloading.
>>64889933He used a slam-fire pipe shotgun to kill the woman. Both of his lutys fucked up.
>>64888914Interesting, I believed open-bolts were banned.Makes me wonder why keltec or some other cokeheads haven't built one to cash in on gang violence.
>>64889582It's a good time to start checking centerfire, apex, bowmans and whatacountry daily, numrich even though they don't seem to be too actively importing. Threads aren't going to be timely the way things have been moving if there are specific kits or hot deals you want to move on.
>>64890384>Slam-bang shotguns are a thing. As simple as you can get before you start going for muzzleloading.It's possible to build some really simple trip wire shotguns with 3/4" pipe too...
>>64890367"Carlos" are the current standard for smgs, although 3dp guns have been making inroads. A semi auto nutty9 is very simple to make with little tooling aside from a 3d printer out of non gun parts for example. If you can make guns even more accessible that's great.https://homemadeguns.wordpress.com/tag/carlo-pistols/
>>64888605There are many that were designed to be easy to make.
If we're talking just getting your hands on a firearm in the US and not worrying about laws then open bolt smg builds from parts kits are stupid simple if you can weld. Building from scratch is also easy with a 3d printer, but even without one open bolt smgs are pretty easy with a welder and grinder, reliable magazines are the bitch because they are the least forgiving part. In the US parts kit builds are pretty doable as long as you can weld since generally someone has already done the work of making jigs and repair pieces, strangely making open bolt SMGs compliant is a lot harder because of all the bolt and trigger modifications that have to be done.
>>64889940but to buy an illegal firearm in a foreign country you need people skills. Something those kind of shit heads usually lack.
>>64890609If I remember correctly, he killed the guy at the kebab shop with the slam fire. The woman got killed with one (if not the only) burst of one of his lutys.
>>64889591>tried to shoot up a synagogue but couldn't get through the door?Literally stopped by WOODEN DOORS, which is something these shitheads love to bring up in their holocaust denial.It's almost poetic.
>>64888605It's not hard to make a simple firearm, if it's legal for you to do so you should try it. I've made some, done some reloading to. It's not worthwhile for common ammo if your time is worth anything and you don't enjoy doing it, it's best for making very precise ammo or calibers that are excessively expensive or hard to find.
>>64888605If the favela monkies can do it, so can you.https://www.youtube.com/watch?v=KpQVQiY9P2I
>>64888719>>64888765You forgot the "in America" part>>64888724>>64888914Mostly this. Pretty sure at the state level in CA and NY it's not legal. I'm not a coastalfag, so I'm not positive about that. In other states, such as Michigan, if you manufacture a private handgun for yourself, you are legally obligated to serialize and register it with the state. IIRC, MI's law regarding this is very weird. In that if you manufacture a handgun, serialize it and don't register it, it's a felony offense. However, if you don't serialize it, it's just a misdemeanor.
>>64888825Neat
>>64889195^thisImprovised and "home manufactured" firearms are completely different categories. Both do require a brain to do so without an heroing oneself.>>64889783ARs are easy peasy. AKs are a totally different beast. You *can* print an AR. With a Harbor Freight drill press and a cross slide vice, aluminum 80's are the way to go though.As for handguns, squirt a glonk or buy a p80 and don't use a fucking hand drill.
I'm a gunsmith in germany and I've tried to 3D print an Urutau at homeThing was damn easy to make, didn't need any gun parts and it worked flawlessly without any malfunctions for hundred and hundreds of rounds
>>64889783Based fellow machinist.
I had an idea from a taofledermaus video that came out like 11 years ago. Check this out: a magazine that feeds from two springs, the reverse one feeds Ramset .22lr blanks, and the fore one feeds some kind of lead .22 pellet. A long bolt will strip them both into an action meant for like a .22 magnum or something.
>>64888605
>>64893290I sense the german wrist wrecker.keep up your great work, Jojo.
>>64895030If anyone actually makes this consider reinforcing the 1 inch pipe and end cap by getting heavier schedule pipe or wrapping the pipe + cap with a thick layer of fiberglass. Plumbing supplies are not made to withstand the pressure generated by a shotgun. No need to be a Darwin award winner.
>>64892920I miss the p80. I have a few of the 76 and can't figure out how to do them.
>>64895446Fourth hole? Or the grid in back? I have one but I'm just saving it as a collector's item.
>>64888724Fuck following the ATFs retarded rules, most of the shit they make up is on the spot just to fuck over some NFA workaround.
>>64892261there were no gas chambers
>>64895378I've never personally built one of these, but I have a weird obsession with homemade ghetto-rigged gats so I've studied the subject extensively.From what I've been able go gather about these things: * They don't reach the same pressures and muzzle velocities as proper factory-made shotguns, mainly due to the "bore size" of 3/4" pipe being significantly larger than a true 12ga shotgun.* The end caps and 1" pipes are more than strong enough to safely handle the pressures generated upon firing, yes, even the crappy Chinese cast iron shit* The only cases I've seen of the end caps blowing off have been on extremely sketchy Brazilian builds where the "end cap" was just a piece of thin plate steel poorly booger-welded to the end of the larger of the two pipes* The main safety issue is case head separation since the pipe caps are concave on the inside, wooden dowels aren't meant to take significant compressive loads, and the headspace is effectively set by how far the firing pin protrudes* Case head separations will cause high pressure gas and uncombusted powder to vent between the two pipes, potentially injuring the shooterTo increase the safety margins of a gun like this, the wooden dowel should be replaced with something stronger, like a stack of washers that has been glued/soldered/brazed together and filed down to fit snugly in the 1" pipe.Ideally, the "breech plug" of the 1" pipe should be made of solid steel, then pressed and CORRECTLY welded into the pipe. It wouldn't hurt if the plug was recessed a bit into the pipe, and the edge of the pipe was heated, folded down, and welded over the end of the breech plug.The firing pin protrusion,it should be kept as short as possible while still being capable of reliably detonating primers.Using some of these suggested methods to fix the headspacing issues would solve like 90% of the safety issues associated with Four-Winds/Slam-Fire type pipe guns.
>>64893290Hey can you tell me if my design could possibly work? (12 gauge bolt action shotgun)
>>64896067Grid in back. I figured it out I think. Slowly cutting out the back. Not too hard.
>>64889582Apex has kits again and I finally snagged a couple. Thanks for asking.
>>64902042Few things that come to my mind:-What do you need the spring for, behindert the bolt, if its a bolt Action?-You need something that locks the bolt in place, the bolthandle most likely won't be enough-the part that holds the rim of the cartridge in place prevents the shell from extracting when it hits the extractorBut keep going, I like your ideas and CAD skills
>>64903052>-What do you need the spring for, behindert the bolt, if its a bolt Action?nta, but my guess is that it's "inside the bolt", so maybe for the striker?also, who do you call behindert? OP? You are probably right. I see no way how this abomination could work.>>64902042Hey OP, I looked at it and I've got no idea how this should work. I am not even sure if I can identify the bolt or the receiver.I am completely flabbergasted. If the hollow tube with the "Picks new shell from the mag" and the "Holds the shell" parts is the bolt, then why does it have no breechface? If my guess is right then the "Holds the shell" part is the extractor. Or at least you want it to be. And the thing that is marked as the "Extractor" is actually supposed to be the ejector. The extractor should not be a fixed piece of metal. And the extractor and the ejector should not be on the same side. See pic related. In this case it is a "top feeding" and "bottom ejecting" system. Just as an example, so you can get the idea. You are free to make your design a "bottom feeder" and I guess "right ejecting" system. The ejector as part of the bolt is also not mandatory. Plenty of guns got their ejector as a part of the receiver.Back to the drawing board, OP.
It's bretty easy and fun if all you want is a holdout pistol or a wall piece. Even without a printer kids in the 90s would make a ton of shit guns using rubber band-tensioned deadbolt mechanisms for the striker. if you want a "viable" gun shits more complicated but there's guides out there
>>64903052>>64903233I hope this new image clears things up a bit.I could move the extractor onto the other side of the bolt but you are right, i would run into ejecting issues because extractor is fixed in place. I will try to design a new one with a spring. I am also from Europe, i wish i was American so i could just try to build it and make solutions as i encounter problems.What if i moved the mag onto the side of the gun so the empty cartridge will be ejected by gravity itself as i pull the bolt backwards? Hm...Anyway, thanks for ideas, i will continue to work on it
>>64904471silk? seems like the wrong choice for a cylinder
>>64904966You need locking lugs or something!Otherwise the bolthandle will crush the tube or even sheer off and the bolt will launch back at youYou can do an easy design like that with .22lr but not with a 12g
>>64888605I made several back in the days before 3D printing, when people had to learn how to run lathes and milling machines to do it.It's not hard. It's kinda rewarding. Not worth the effort and expense unless you live in a dictatorship like the leftards are trying to impose on the U.S. and Europe. Worth it for that reason, however.
>>64888825Holy shit I need this. What's the name of the remix?
>>64888914>>64890611I mean, nowadays there isn't much point since FRTs and "switches" can be printed in just a few minutes on any 3D printer.
>>64905768It was, indeed, the wrong choice for a cylinder
>>64902042>>64904966The whole thing seems fundamentally flawed unless theres invisible parts. Like theres no actual bolt or breechface.Theres a hollow shell that you call a bolt but no.
>>64904966>the empty cartridge will be ejected by gravity sounds like a bad idea. Relying on gravity alone for the ejection will not be reliable. Just a little bit of dirt and you will run into issues.There are probably too many issues with this design to address them all on here. Let me give you just another example. You are designing it with a pretty straight walled box magazine. You will run into issues with rimlock, because the rims of your 12 gauge shells will interlock and this will cause feeding issues. Unless you are very careful during the loading of the magazine.Let me give you an advice or twoFirst - make yourself more familiar with the inner workings of guns in general.Go and watch a ton of gun Jesus' videos. There are many obscure designs choices out there and you will see how they work together.Or even better, C&Rsenal. If you got a lot of time there is no better series imo:https://www.youtube.com/watch?v=B4vfqLkQC6g&list=PLJvsSlrbdhn5v8AuvAZuOYJ5BgEEoDdqmSecond>I am also from Europe, i wish i was American so i could just try to build it and make solutions as i encounter problems.So what, I see no problem in building mock ups. Make em from wood or 3d print your stuff. You could even get some dummy rounds and you could pretty much try everything yourself. Loading, feeding, ejecting. Everything except the really fun part of course. As long as you are not building stuff with actual pressure bearing parts, there should be no problem. Just don't be stupid and don't do anything illegal. There is plenty of stuff you could do to satisfy your mechanical curiosity.And maybe, once you got a more or less working design, you can show it on here and maybe some bored Yankee will try to rebuild it and give you some feedback.Don't let your dreams be memes.Oh, and work on your CAD skills. I know that you are going for simplicity, but try to make it at least a little bit sexy. Not just cylinders, tubes and rectangles.

>>64910287Thanks!
>>64905874I hope the transfer of energy will go into the last component which is the one spring loaded with firing pin and it will just cock the gun on itself and not explode>>64906700Added some things>>64907067Magazine is just symbolic, gun is designed for Saiga 12 mags.Thanks for recommendations, i will try to build the gun out of plastic tubes and wooden parts to see if it can work. New design got a little bit long because i decided to add additional spring to make sure it has enough power to fire the primer, but it can be shorter with a stronger spring. Redesigned the bolt and moved magazine to the side. (Also added symbolic stock and handle)
>>64918487Do I get this right, you hope that if you fire the weapon that a part the energy will cock the firing pin? How? And if the recoil goes into the firing pin, how will your gun not just explode into your face.Your bolt handle is fixed to the bolt, which is one part, right? So your whole bolt will turn as you open and close it. Including those cut outs for the magazine. Anon, honestly, think about it. You will just fuck up the feed lips of your magazine.Let us assume that there is a reason for why people don't build bolt action shot guns. Maybe you should go with something simpler and learn more about the inner workings of a gun.
>>64919025>Do I get this right, you hope that if you fire the weapon that a part the energy will cock the firing pin? How? And if the recoil goes into the firing pin, how will your gun not just explode into your face.I'm not the guy who drew this design, and the design seems to lack the facilities for it, but using "primer actuation" as a means to re-cock or even cycle a firearm is an actual thing.The entire concept is to allow gas pressure of the round firing to push the primer out a few mm, acting like a tiny gas piston, and using this to operate the firearm.Some of John Garand's early rifles worked that, they also used special ammo with deep primer pockets and long primers.The system never got popular since it's not very practical, especially not with rifles, but I can see a system like this working in this scenario.Shotguns seem better suited for such as system since they operate at lower pressures and most modern shotgun shells use 209 primers which are good and long.But it would require some modifications to the striker and bolt face. pic rel.Also, some other features of the design, such as the long spindly firing pin, the tip of which is just flopping around outside the bolt when the action is cocked, are very bad.There should be a proper firing in channel in the bolt, and while the striker is fully cocked, the tip of the firing in should remain inside the firing pin channel in the bolt.Just having it flopping around loosely and hoping everything lines up when the trigger is pulled is retarded.All that being said, I have no idea if a 209 primer would hold together in a scenario like this, or if the primer would just blow apart and dump a fuckload of gas into the gun/shooter...So if someone were to actually build a gun using this concept, they should testfire it with a looong string first.
>>64919170Wow, I did not know that. Thanks anon.
>>64919025Hopefully the movement of the bolt will be small enough that it won't damage the feed lips but if it does i will just cut it like pic rel.(also the extractor is enlarged for visual purposes)>Maybe you should go with something simplerI don't know anything simpler than this except for a slam fire shotgun but building them is pointless.>>64919170That gave me another few ideas, i will think about it. I want to make the gun as simple as possible and from as little parts as possible. If i make it too complicated the gun would lose it's purpose but i will try to figure out a way to create a proper channel to guide the firing pin.
>>64919434now that you posted a better look.your bolt face isnt strong enough to actually contain a 12guage the whole thing needs to be redesigned most likely trashed.
>>64919489>your bolt face isnt strong enough to actually contain a 12guageI could add more material into the bolt and drill a hole for a firing pin if necessary but Saiga 12 bolt face looks very similar and somehow works. I assume the most pressure will be inflicted onto the barrel which is sleeved with larger tube
>>64919665its going to go path of least resistance, you have no locking lugs and most of it is hollow
>>64919434>I don't know anything simpler than this except for a slam fire shotgun but building them is pointless.It all depends on what your point is. Home defense, range toy, overthrowing the government. If you want it to look less improvised you could try and rip off the Cobray Terminator design.https://www.youtube.com/watch?v=WnpOis10NyQhttps://www.youtube.com/watch?v=sYf1SXBY_E4If you want more firepower than a single shot, try the double barrel approach. Or make a behemoth version of the COP .357 Derringer in 12 gauge. a quad barrel breech loading shotgun should be much more easy to do and probably more reliable than the design you are coming up with.From what I've seen so far, I am assuming that you don't have access to a lathe or a milling machine. My guess is that you want to do it all with hand tools and stuff from the hardware store. Your approach seems to be pretty naive tbqh. Don't be stupid and don't blow your hands off. Stay safe anon.
>>64919665In that Saiga, the pressure is held entirely by huge steel locking lugs that lock into the trunnion at the barrel, then a little gas is vented off to actuate a mechanism that unlocks those lugs as the bullet exits the barrel to allow the bolt to travel. What you've drawn has absolutely nothing to hold it back, it's just a straight blowback, so only the inertia of the bolt at rest is supporting the round. You'd need to push the bolt to be nearly 3lbs for it to work safely, and even then it wouldn't work consistently with different ammo types, shotgun loads vary too much to take advantage of a straight blowback reliably. We don't make straight blowback shotguns for a reason. You're missing some basics, anon.

About 3d printing, is there a way to upload stl files to the printer fairly privately? I have the bambu labs printer and splicing software. My main concern is that when during the process of splicing the files for an upload to the printer, it’ll save somewhere I don’t want it to. The best solution I’ve found online is printing it without wifi I don’t think that will be possible with my current splicing software. Any advice is appreciated
>>64923497It's called a MicroSD card nigga. Slice on your computer, gcode onto the card, card into the printer. None of my printers have ever been connected to my network.
>>64902042>>64904966>>64918487a quick glance over it tells me theres a lot of complexity for a design you originally intended to be very simpleyou will spend ages on the mechanism yet the design pays no attention to any of the ergonomics, and you'll likely struggle heavily with reliability because it doesnt look like you intend the tolerances to be very tightmechanisms like bolt actions or delayed semi autos are better suited for someone with greater manufacturing capabilities, but its doable with enough timeI reccomend some quality of life additions like adding wood pistol grips, a better shaped buttplate with padding to mitigate the recoil (its probably going to be a lightweight gun), a more ergonomic trigger (if you can do the other parts you can make a better trigger), a forend or maybe even just a heatshield like you see on the ppsh that is preferrably a bit weighty because that 12 gauge barrel WILL burn your hand, and atleast a basic front sight, or even better would be some really basic express sights which is just a bead and a very wide and shallow V notch on the rear sight
>>64888719>>64888765>OP photo is a luty Yeah but making fucking whole hog machine guns without an FFL whogivesafucklevelwhatever is most certainly dog shooting ruby ridge shit
>>64935054To be clear though, it's not unlawful to make or own a fully automatic firearm in the USA and nobody in the US has ever been convicted of owning a machine gun because it's simply not a crime.
>>64935005>>64921964>>64921369>>64919705Thanks for advice, i made some changes:Bolt is now one long metal part (Steel rod welded into a steel tube) with cuts only for magazine feed lips.It has a fixed firing pin (i got rid of the long nail striker thing)It has fixed extractor (it's simple and i just need it to guide the cartridge back)Magazine feed lips are used as ejector.After the trigger is pulled, bolt travels forwards, picking up the cartridge from the mag and guiding it to the barrel. After the shell goes slightly up due to barrel feed ramp, the primer aligns with the firing pin and the gun fires.Energy makes the bolt go backwards, extractor guiding empty cartridge until it hits the Magazine feed lips (ejector). Then, the bolt goes back enough that the magazine can feed next round.If the trigger is kept pulled, the spring makes the bolt go forward again and the thing goes BANG BANG BANG fully automaticWould that be possible to work?From problems i can think of:-Magazine feed lips would get damaged (but i assume it will probably take hundreds of rounds)-Cartridge will fall out of the ejection port during loading (unlikely because when the magazine feed ramp ends, the tip of the shell is already deep enough to avoid the hole but still, ejection port must be kept as small as possible) -Extractor fixed in place will cause problems if there is no enough space inside (i can grind the metal inside the receiver or buy slightly bigger tube to make more wiggle space if that happens)Also, the handle can be pulled back and twisted up at the end where the cut is, which works as safety. I hope the image is good.(If the mechanism can possibly work, i will design things like heat shield, recoil buffer etc.)
>>64937329if this is a 12guage youve described an open bolt its going to explode and kill you. unless the whole things like 10 lbs with a huge ass spring.
>>64890740Just got a cetme c kit and five .308 barrels from apex, maybe I'll build something but in all honesty it'll probably be added to my expansive parts kit collection. Right now my firearm attention deficit is pushing me to try to make a hybrid diy bolt action in a bottlenecked cartridge.
>>64937329d-do y-you really want to build an open bolt submachine gun? In 12 gauge?And somehow it looks even worse than a sten.Why this obsession with 12 gauge?If you want to go down this route, at least make it 9mm. But then again, there are a million different designs out there already.
>>64937329Still missing some basics, anon. What you've drawn has absolutely nothing to hold it back, it's just a straight blowback, so only the inertia of the bolt at rest is supporting the round. You'd need to push the bolt to be nearly 3lbs for it to work safely, and even then it wouldn't work consistently with different ammo types, shotgun loads vary too much to take advantage of a straight blowback reliably. We don't make straight blowback shotguns for a reason. We don't make straight blowback shotguns for a reason, anon.
Is there a printable p322 magazine model? They're so damn expensive. I've been looking for one but to no avail.
>>64940370None that I have seen, but there are printable mags for several other 22s and the P322 mags are fat with fat polymer feed lips, so it should be doable. Get on it, anon. I bet you can get some calipers and a spare spring for less than a new mag.
>>64937761Almost 1/3 of the gun is reserved for the spring.>>64938686>Why this obsession with 12 gauge?12 gauge does not require you to rifle the barrel, 9mm must create projectile twist while shotgun barrels are just tubes.(I know about ECM barrels but they still seem complicated to make)12 gauge creates actually very small pressure during firing(much smaller than 9mm), it does not need strong locking lugs etc. Also, shotgun components are bigger so they require less precision during cutting/welding.>>64939652>What you've drawn has absolutely nothing to hold it back, it's just a straight blowback, so only the inertia of the bolt at rest is supporting the round.I don't know what do you mean by this. Is there some component i have to add?>You'd need to push the bolt to be nearly 3lbs for it to work safely.Why would the bolt need to be above certain weight? I assume it will be responsibility of the spring to absorb the recoil. Spring must be weak enough to let the bolt go backwards but strong enough to keep the gun intact. (it will probably take few tries before i find the proper spring)>it wouldn't work consistently with different ammo typesThat's a small problem. If cartridge is too underpowered to cycle then it will work as a bolt-action.>We don't make straight blowback shotguns for a reasonI guess you are right, if it was that easy then someone probably would have made it by now but still, i want to give it a try and at least learn something if i fail.
>>64941564>12 gauge creates actually very small pressure during firing(much smaller than 9mm), it does not need strong locking lugs etc12 guage has lower pressure but over a much larger area. It needs stronger lugs than 9mm.
>>64941626Yeah but it's not much anyway. For example: (6:12 exact minute)https://www.youtube.com/watch?v=SKbC7ldO3fYStill, that applies to my previous bolt-action design, my new one does not lock the bolt
>>64937823>Right now my firearm attention deficit is pushing me to try to make a hybrid diy bolt action in a bottlenecked cartridge.some fag released files for that exact build
>>64941658you are going to die if you continue being this retarded.
>>64941834Shhhhh... just let it happen man.
>>64941790Where? I just did a pretty deep dive on the guncadindex, odessy and yeggi and didn't come up with anything buildable
>>64941564>I don't know what do you mean by this. Is there some component i have to add?>Why would the bolt need to be above certain weight? >I assume it will be responsibility of the spring to absorb the recoil. Spring must be weak enough to let the bolt go backwards but strong enough to keep the gun intact. (it will probably take few tries before i find the proper spring)Anon, if you're not trolling, you really need to learn the basics about how firearms work before continuing.
>>64941564>Spring must be weak enough to let the bolt go backwards but strong enough to keep the gun intact. (it will probably take few tries before i find the proper spring)spring doesn't really have an effect on delay, it's the mass of your bolt that matters.
>>64942384Now that i think about it, bolt must stop for the gun to fire so the energy from the spring does not give a lot, i get it now.12 gauge generates 3x lower pressure than 9mm but has 4xarea. From what i found, 12 gauge creates 30% more force(or bolt thrust). It's more but not that much.Typically for 9 mm blowback, like Uzi for example, the bolt weights 1.5 lbs (700 grams). My bolt currently is about 2lbs (900 grams) and that would be already more than 30% increase in weight so unless the scaling does not work that way, it should be enough. One anon said the bolt must be 3 lbs but did not say how he knows or calculated that? If that was the case then yeah, the shotgun would be too long to be worth constructing in current form.From possible fixes i could increase the diameter of both bolt and the receiver, meaning heavier bolt in shorter form but that would complicate things a bit and it would be easier to try and make some other gun.Still, i think this design is worth to be build at least once, just to make sure that it indeed explodes and doesn't work by some chance.

>>64943141Stop linking to that old shit, it's full of errors and inconsistencies and complete bullshit like 88gr 9mm, I wish the site would die so people could stop sharing it. It's just leftovers from the original Orion's Hammer blog which was a misinterpretation of an old George Chinn doc. Just stop with that shit, it gets passed around by people who don't understand it or just haven't actually read it. Send people to the unmolested original instead, https://archive.org/details/TheMachineGunVolume4ByGeorgeMChinn>>64942927It does not scale that way. I said 3lbs off the top of my head and frankly I was underestimating. At 3lbs with common loads you'll be pushing 10-15m/s bolt velocity, and that's still way too high. You'd be looking at more like 7-8lbs to keep things safe with most loads, but there's still plenty of off-the-shelf stuff that would fuck it sideways. When a cartridge fires, pressure acts on the bullet base and on the bolt face through the case head simultaneously. The ratio of those two areas, case head diameter squared over bullet diameter squared, defines how the total force is distributed between them. That ratio is applied to the bullet's momentum to get the bolt's momentum. Momentum is just mass times velocity, so once you know the bolt's momentum, dividing by the bolt's mass gives you its velocity. You can go the other direction to get target velocity instead. For a simple blowback, 4-5m/s is usually the target range for bolt velocity, there are exceptions but don't try to be one. Pick a random cartridge: Federal Top Gun 1oz #8 shot, that's rated for 1180fps, that'd be 1352ftlbs of energy. Bullet (wad, in this case) base diameter is .729", case base is .875", area ratio is ~1.44. The get 4.5m/s out of it, that would put the bolt at 115oz, 7.18lbs. Load up some Federal Speed-Shok into that same gun with that 7.18lb bolt and it'll hit nearly 7m/s, extract too quickly, and rupture the case.
>>64937823This is seeming ill advised, but then again there's a 7.62 pipe gun in the improvised munitions handbook with less steel involved. I do wonder how much a tight printed rifled bore line changes the pressure vs loose fit pipe the army was suggesting.
>>64943278Well, i got one more idea before turning my shotgun back into being bolt-action.What if i gave the barrel ability to move forwards and backwards a bit and link it to the bolt during firing?So when the bolt meets the barrel they link and the shot is fired, energy must kick back both the weight of bolt and barrel combined together (meaning bolt can be lighter) and since barrel is also a chamber, it moves back along with the empty shell delaying extraction. Then they separate and the bolt cycles.If i found a way to make them attach and detach when i need them to, do you think it could work?
>>64943976Ask Gaston Glock and John Browning if Short-Recoil works.
>>64943976all these concepts could work but you will not be able to make it work safely. you seem to be watching random videos and getting the exact wrong message from them. these guys did it so thats mean i can. make something with a locking mechanism or a break action.no your fucking slot cut into a metal tube with a hardware store bolt through it doesnt count. its going to sheer the bolt off while the slots going to enlarge
>>64942927Honestly, your shit reads like a poor man‘s failed paladin press concept. And this should ring some alarm bells.If you want to commit suicide and make it seem like an accident, go for it.

>>64945595Theres no bolt
>>64945605Technically the barrel acts as the bolt.
>>64941564Okay. You clearly don't get this. Scrap this.Return to monke. Back to basics.A firearm is a cannon. What do you need for cannon? Tube with proper thickness, yes. But you also need something at the end. And it is FIXED structure. Now i'm going to explain to you why. There's an explosion and the forces need to be contained so they will go in the direction you want. Which is following the path of the barrel. That's their direction of least resistance. And the end cap needs to be as thick if not thicker than the barrel. AND the barrel and the back plug needs to be thiccc at the base of the cannon because prior the projectile being accelerated by the gasses, there will be a build up of gasses and pressure. Not only build up of gasses but an explosion. You don't need to profile the barrel, but it needs to be thick enough to withstand this fluctuation of pressure. This means "just a tube" wont do. You resolve the thickness and materials through engineering. Physics calculations. That's engineering. But you can also just make assumptions based on common knowledge and craft it.Now. Lets talk about semiautomatic firearms. We can talk about locking lugs later but lets focus on blowback firearms right now. Blowback firearm concept is that there's the explosion is vented in two directions. Front and back. The bullet is lighter of the two, therefore exits the barrel faster. The explosion occurs at the very base of the barrel, and the bolt is heavier, so it accelerates slower and for shorter period of time. the bolt is a modified concept of the cannon's back plug.A locking bolt is as much bolt as blowback bolt, but it's locking... like a lock. It doesn't move. And it needs to be strong enough to operate as a solid piece with the barrel, until it is opened by hand or other force.A modern firearm is a puzzle which forms A CANNON.
>>64945621the receiver is the bolt.
>>64945621>>64947256There is no bolt. You have the breech face and chamber/barrel.Not every gun has a bolt or equivalent structure.

Trying to ecm just so I can say I did, going kind of how I expected but I'm ordering a $10 pump rather than dicking around with the 3d printed one.
>>64958532It's fun, but yeah the unnecessary DIY stuff is just unnecessary. Once you get the process down it's really easy and really gratifying. I recommend doing it in a room with a TV, a comfy seat, and beer - the best results come from going slow and inspecting often.
>>64958575I was trying to just use what I had around, 6 amp power supply, printed housing for the biggest spare dc motor I had, but yeah it's way more trouble than it's worth without self priming. It did get me from 7.8mm to 8.4mm before I threw in the towel. A better pump will be here next week.

>>64966546Refute it. Show me the law that says American citizens cannot make or own a full-auto firearm (we can), and cite a case where someone was convicted of possession of a machine gun (a crime that doesn't exist). This is where you come back with "it requires a tax stamp you can't get!" and I have to explain to you how that supports my claim that it's perfectly legal. Then you pull out of a bunch of cases of people convicted of a whole litany of crimes related to firearms but none of which will be possession of a machine gun, because again, that's not a crime. Go ahead, get us started.

>>64966756>>64966775Okay I'll be honest I didn't think you'd struggle this hard. There are examples of people being convicted for simple possession per 922(o), even pretty recently.

>>64966775How can you transfer something you don't own?
>>64966822I see, you're totally unfamiliar with that case you just cited.
>>64947191I made some changes.For the bolt action, now the firing pin is inside the bolt, and the middle part which houses firing pin spring is made of wood (it can be made out of metal but working with wood is easier).Only bolt handle with locking lugs can spin, the rest of the bolt only moves forward and backward.It has a safety mechanism, firing pin is retracted unless bolt is fully locked to prevent it from becoming an accidental blowback.The locking lugs might seem to be too weak, but if that's the case i can make them thicker and thicker until they finally will be enough (it will only cause the bolt and the gun to get a bit longer)As for the blowback, it works the same as before but now i added one large tube and 6 lbs of additional weight to the bolt. You are supposed to fire it like a rocket launcher with sights on the side of the gun. From my calculations, it won't be bigger or heavier than a 50 BMG Barret so it still should be usable.Even if it isn't, i will still build it because it will be cool to have one even if it's just a non-working prototype.As for my next design, it will probably be a double barrel break-action shotgun so it should be much easier/safer to make.
Be careful friends, i heard they grabbed the parrot. Skimming through the articles they claim he was advertising homemade guns for sale but i thought he was smarter than that so who knows. I was interested in the other stuff he was cooking up too.
