3D Printed Guns?

But, I suppose it's just because people want to know the opinions of their favorite community: the Haven and Hearth forums!

As long as it stays somewhat civil... yeah, a lot of us like a good discussion. Opinions usually don't change, but you never know.

Regarding casting, I wouldn't trust a home cast barrel. It's very easy to get bubbles or other imperfections in it, and that's gonna make the gun explode in your hands. I'm guessing all hobbyists gunsmiths forge their barrels.

the only gun modification or part that's illegal where gun laws actually matter is a fully automatic sear block

most times in semi autos that are publicly available there's a catch for the hammer that literally just needs to be physically cut off.

in canada or the islamic union any gun you can get isn't going to have any considerable modabibility and it's really a non-issue

the only illegal guns to get are easy as fuck to make, for example, semis to full autos

also you'll never make a functioning gun with a 3d printer without a metal lathe and the skills to use it - plastic or polymers and synthetics that can be 3d printed would melt if used as a barrel, receiver, railing, suppressor, flash suppressor, or gas tube. on top of that, another complication of any barrels is rifling. you need specific kinds of metals to make a good rifling.

so no 3d printing is a meme. you can make a zipgun that would fire one bullet off at a close range, but if you expect it to function like a factory made AR/M4/AK/what ever the fuck ever literally ever, it will not.

At that point you're better off getting a metal tube, a nail, and a hammer, because that's all a gun really is.

From what I've read the barrel of the gun is the tricky part that ends up getting too hot and messing up after a few uses, but as someone already said, a workaround for that is to just use some metal pipe.

Seems pretty possible to make a fairly reliable gun using mostly 3D printed parts.

The thing about not being able to get bullets does make it harder, but I don't live in America so I'm asking, how common is it to find bullets in a person's home? Or in the glovebox of a car(?)

metal pipe is a silly work around. you'd be firing a musket ball with a shape. it'd tumble, dramatically lose acceleration, and quickly fall to the earth relative to a rifled barrel. rifles are called rifles because of rifling, that swirly shit you see in bond intros is the barrel of a rifled handgun.

Nobody expects a plastic gun to function as anything other than a zip gun. If anyone has read more into the posts here than that, then they don't understand the subject. Question is how much range and power you can get from it. Some are only useful if you stick the end of the barrel right up on the target, some have enough strength to actually fire a round more a few meters with reasonable accuracy. I mean, you can fire a .22 round out of a ball point pen barrel in an emergency if you just have to have a gun. (You're better off using it to stab someone in the eye, though. You might actually kill them that way.)
