Pretty much this.
Unless you know what you're doing, anything more complex than the stupid slam bubbashit royalnonesuch makes is dangerous.

That being said, if you're looking for some good designs to go off of for gun-smithing, than late 1944-1945 stuff from the axis is good for cheap and easy designs ripe for improvement.

Pic is technically related by origins.

>>28477620
I have thought of a VG 1-5 ish design made from an AKM receiver with a fuck huge slide riding on the original AKM receiver rails as well as an underslung slide rail like the VG1-5.

The trunnion is a new part, as it is a blowback gun. Instead of having the sight block pinned on top of the barrel, an under hanging slide rail is pinned on. The slide assembly is more or less a copy of the VG1-5's, modified to use more modern pistol sights, and perhaps a manual slide stop. To retain the rear of the slide, use a slide cover that fits on the receiver using the rear trunnion's original recoil spring hook and the selector lever.

I found a nearly completely destroyed stevens single shot 12 gague in the ceiling of a moldy basement. Only thing I could salvage was the barrel and a few token trigger group parts. I intend to build a new receiver and stock for the rifle, along with new breech and hammer/trigger group mostly based off of cobray derringer receiver but scaled up to accomodate 12 gague. Anybody else have some proje ts kicking around in thendark corners of their imagination?

>>28476398
Since I realized that shotguns are superior to homemade subguns, I've had the urge to build a multi barrel .410 shotgun pistol with 8"-10" barrel, only problem is finding rifled barrels/liners for a decent price.

In an attempt to make this thread not die.
12 gauge is fairly low pressure so slam-fire pipe guns are "relatively safe."
How about something like 7.62x54? Its rimmed, so single shot variations of a rifle would be simple. But does it create pressure beyond the rating of an ordinary pipe?

Single shot guns are piss easy to build as long as you aren't stupid about it. Designs for derringer pistols are everywhere and can be modified for rounds larger than .22lr. Just don't go crazy with it and look up the different pressure ratings for building materials and calibers used. Crickett made a shotgun, .22, and I think he has a 9mm rifle based on the derringer design. This is his shotgun:

Quick question.

What's the ATF regulations and laws concerning firearm making? I'm trying to find info but it's kinda all scattered.

Want to get into metal working and it might not be beyond me to experiment with guns in the future for my own amusement.
>>
>>28480602
Follow normal firearm laws. No sbr and sbs, dd are not good. You don't need a serial number unless you plan to sell it.
>>
>>28480700
So if i want to make a simplistic as possible bolt action so long as it's not short barrel or considered destructive device all should be good?
>>
>>28479727
There's some fuckery with multiple barrel weapons and the ATF. It's a volley gun or something, which isn't a machine gun.
>>
>>28480761
Yeah just follow all firearms laws. Also check your state laws, I know California has laws against making zipguns.

>Unless you know what you're doing, anything more complex than the stupid slam bubbashit royalnonesuch makes is dangerous.
Maybe if you're a drooling retard. You really only need a basic understanding of mechanical engineering and the ability to study existing weapon designs. Being smart enough to test fire your weapons from a vice helps too.

you can buy an insert that will house up to a .45 for like 20 bucks. That being said, I made a solid steel one and it will take a 410 shell.

They all take a chemist to make. If you don't have an advanced understanding of chemistry then you shouldn't try to make any of these. If you do have an advanced understanding of chemistry then chances are you already know how to make explosives and have done it at least once.

Besides, most recipes posted on 4chan will blow up in your face or make a poisin gas to kill you.

tl;dr. DON'T MAKE ANY OF THESE UNLESS YOU ARE A CHEMIST
>>
>>28480823
they have to be fired at the same time
More than one bullet fired in a "single trigger action" is considered a machinegun
>>
>>28479671
Are you kidding me? It's way over 20,000 psi. Like I don't know exactly what it is, but I know it's over that
>>
Hypothetical. If you got 1000fps with 50gr bullet would you get 1500fps from 25gr bullet? Case volume stays the same.
>>
>>28483795
Not exactly. Look at any reloading manual (downloadable for free from smokeless powder manufacturers like Hodgdons) and velocity does not go up exactly proportionally to weight of bullet. There are many reasons, including: different ballistic coefficients for different bullets (how air resistance affects them due to shape), limits on how much pressure is allowed for a particular cartridge, minimum length of barrel needed to burn different types of powder completely, etc.

>using airshit barrels or brake line
Both of those are a shit.
Make a barrel instead.
The problem with both of those are that they are too large.
The internal diameter is so oversized that most of the gas pressure goes around the bullet rather than push it out. That means the bullet leaves the barrel with a speed significantly lower than a shitty 100 dollar Chinese air rifle. Such a rifle is much more accurate as well.

When you make your own unrifled barrel the accuracy is still shit, but at least the bullet hits just as hard as a bullet fired from a manufactured .22lr firearm.

I've experimented personally with this, and a standard velocity bullet fired from a barrel with a 6mm inner diameter BOUNCED off a half-inch pine board when fired from approximately 3 feet away.
A standard velocity bullet fired from a barrel with a 5.5mm inner diameter will pierce at approximately 3 inches of pine board when fired from the same distance.
>>
>>28487342

This. Although it gets very tricky to make a true bore on anything longer than 5-6 inches.

Here are some ideas for rifleing cutters that can be built for relatively low cost.

Anybody have other resources for those who lack lathes and fine tooling? Seems like the methods below would be harderto do for smaller calibers just because the tools are smaller and thus harder to make.

So if i want to make a barrel what kind of drill bit sizes do i need for different calibers? No amount of google searching has helped.
>>
>>28491062
Which calibers do you have in mind? Basically measure bullet and match the drill size.
