PIPE OR “ZIP” GUNS
Commonly known as “zip” guns, guns made from pipe have
been used for years by juvenile punks. Today’s Militants
make them just for the hell of it or to shoot once in an
assassination or riot and throw away if there is any danger
They can be used many times but with some, a length of
dowel is needed to force out the spent shell.
There are many variations but the illustration shows the
First, a wooden stock is made and a groove is cut for
the barrel to rest in. The barrel is then taped securely to
the stock with a good, strong tape.
The trigger is made from galvanized tin. A slot is
punched in the trigger flap to hold a roofing, which is
wired or soldered onto the flap. The trigger is bent and
nailed to the stock on both sides.
The pipe is a short length of one-quarter inch steel gas
or water pipe with a bore that fits in a cartridge, yet
keeps the cartridge rim from passing through the pipe.
The cartridge is put in the pipe and the cap, with a
hole bored through it, is screwed on. Then the trigger is
slowly released to let the nail pass through the hole and
rest on the primer.
To fire, the trigger is pulled back with the left hand
and held back with the thumb of the right hand. The gun is
then aimed and the thumb releases the trigger and the thing
Pipes of different lengths and diameters are found in
any hardware store. All caliber bullets, from the .22 to
the .45 are used in such guns.
Some zip guns are made from two or three pipes nested
within each other. For instance, a .22 shell will fit
snugly into a length of a car’s copper gas line.
Unfortunatey, the copper is too weak to withstand the
pressure of the firing. So the length of gas line is spread
with glue and pushed into a wider length of pipe. This is
spread with glue and pushed into a length of steel pipe with
threads and a cap.
Using this method, you can accomodate any cartridge,
even a rifle shell. The first size of pipe for a rifle
shell accomodates the bullet. The second accomodates its
wider powder chamber.
A 12-gauge shotgun can be made from a 3/4 inch steel
pipe. If you want to comply with the gun laws, the barrel
should be at least eighteen inches long.
Its firing mechanism is the same as that for the pistol.
It naturally has a longer stock and its handle is lengthened
into a rifle butt. Also, a small nail is driven half way
into each side of the stock about four inches in the front of
the trigger. The rubber band is put over one nail and
brought around the trigger and snagged over the other nail.
In case you actually make a zip gun, you should test it
before firing it by hand. This is done by first tying the
gun to a tree or post, pointed to where it will do no
damage. Then a string is tied to the trigger and you go off
several yards. The string is then pulled back and let go.
If the barrel does not blow up, the gun is safe to fire by
You should not attempt to register such a gun.

We have a couple of threads relating to pen guns on the go.If you have something useful to add, add it to an existing relevent thread instead of starting a new one.These “plans” are all over the internet and are in the various ACs so we all came across this at one time or another.This thread is now locked.
