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 whatever
Luty's design is aged and you can't find a lot of that shit anymore.

In 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.

>>64888605
I have "made" 10+ firearms. Mostly from parts kits available online. AMA

>>64889056
Are the kits cheap and what material are they made from?

>>64889113
>are the kits cheap
No. They will always cost more than the last time you looked so you should buy now.
>what materials are they made from
Parts 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.

There 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.

It'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.

Mostly 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.

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.

>>64895378
I'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 shooter

To 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.

Few 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 extractor

But 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.
>>64902042
Hey 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.

I 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

silk? seems like the wrong choice for a cylinder

>>64904966
You need locking lugs or something!
Otherwise the bolthandle will crush the tube or even sheer off and the bolt will launch back at you
You can do an easy design like that with .22lr but not with a 12g

>>64888605
I made several back in the days before 3D printing, when people had to learn how to run lathes and milling machines to do it.

>>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 two
First - 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=PLJvsSlrbdhn5v8AuvAZuOYJ5BgEEoDdqm

Second
>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.

Magazine 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)

>>64918487
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.

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.

>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.

I 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

>>64919665
its going to go path of least resistance, you have no locking lugs and most of it is hollow

If 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.

In 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. Watch these, and keep designing guns:
