There are hundreds of millions of guns here now, if they stopped
making them tomorrow.

Before too long someone will figure out how to make an automatic
weapon on a 3D printer. Control that.


As soon as they make a 3d printer that works with steel "ink".
Right now all they can make are the parts that don't see the pressures
and the impacts. Guys have made the frame and some other parts.
OTOH those parts that can't be plastic are generally consumables so
they are not serialized or controlled. (barrels, firing pins,
extractors, springs and such)



There's at least one handgun called "The Liberator" that is completely
plastic and 3D printed except for one part. It uses a common nail as
the firing pin. Everything else, including the barrel, is plastic.



I saw that and I saw him fire a shot out of it but I bet up around
round 2 or 3 it is a musket and after that it is potentiality a
grenade. (even with a relatively wimpy round like the .380 this gun
shoots)
Barrel erosion will be a serious problem, even in a single shot gun
like this.
To make a real gun, you need a steel barrel, particularly an
"automatic" weapon like Wayne described. The physics of ejecting a
round and loading another one requires some mass too.

I made single shot "zip guns" when I was about 12-13 but I would not
try to make anything that was a repeater. You can make a very
serviceable single shot 12 gauge from stuff you get at Home Depot. The
best pipe is actually from the "monkey bars" down at the grade school.
You will have to trick someone into threading it tho. ;-)

Even the 3D printers of today can be used to make high precision
templates which an amateur machinist can use with jigs, routers,
Dremel tools, etc. to turn out everything that's needed. It's just a
matter of time before the plans show up for downloading along with a
couple of "how to" videos on YouTube.


If you have a lathe and a milling machine you can make pretty much
everything but the barrel, assuming you are making a rifled bore.

I made a smooth bore .22 that worked from a car antenna and a bunch of
fiberglass wrapping. It was chucked up in a cap gun with most of the
hammer filed away. The problem was the brass came out the back almost
as fast as the bullet went out the front.

Sounds like you're in the same "lucky to have survived childhood"
category that I was. Nowadays you also have to make a video of it to
truly qualify as a stupid kid trick.

It's fairly easy to improvise a crude milling machine if you have some
woodworking tools, small grinding wheels, cross slide vice, etc. I
have no idea how to make a rifled barrel but it's not really necessary
for short range. There's probably something on YouTube however.
