Zip gun band

They came with 10 rounds of. The grip was made to stow a few extra rounds. They were intended to be picked up by resistance fighters, and used to kill an occupying enemy soldier and relieve him of his gear and weapons.

They were intended to be used at very close range, up to about five yards. The users best bet would have been to put it right against their targets head or chest. Of the one million made, only a few thousand were actually ever dropped. No one knows how many were ever actually used, although there is an historical picture of a French resistance fighter with one stuck in the front of his pants.

The idea behind the Liberator was based in its name. It was intended to liberate an occupied people. In essence the Liberator was nothing more than a zip gun.

A zip gun is a cheaply, quickly made gun, usually a single use. Often the zip gun was as dangerous for the shooter as it was for anyone the shooter may be pointing it at. Most often the zip gun is made in a smaller caliber like. This is because cheap, readily available materials, like fuel lines and brake lines, are used as the barrel. Conveniently, fuel lines and brake lines are about the right diameter for that caliber too. In a previous article, I wrote about making a single shot shotgun I call a slider shotgun.

Those actually originated in the Philippines during WWII when the citizens tried to fight off invading Japanese armies. The Filipinos called it a paliuntod; now there are videos all over YouTube, and they are called all different names. In that article I also mentioned having made a 20 gauge, single shot , zip gun shotgun when I was a kid. Because of that they needed a smaller, more easily concealed gun. Small caliber cartridges for a zip gun are just advisable for your own safety as well.

Pistol cartridges like a 9mm have very high chamber pressures and so trying to use that in a zip gun would likely cause you to lose some fingers, if not your whole hand. If I were going to make a zip gun for myself I would say that a. Maybe a. Most often people will use the. If for no other reason, it is because of that readily available tubing diameter factor. All federal law must be observed. Most zip guns do not have rifled barrels. If you find a short length of tubing that is strong enough to withstand the pressure you are half way there.

Brake line tubing is often used because it has an acceptable inside diameter, and it is a hydraulic pressure line, so it can withstand the pressure of a. The two rods are reversible if the operator desires, since the only reason the restrike rod stops short of ejecting a round is that it is not physically long enough: both rods push on the same mechanism in the same way.

An inspection port on the top of the weapon allows the user to check if the weapon is cocked or not. A hex wrench is mounted on the underside of the top cover plate and is used to disassemble the weapon, along with a recess for using the entire cover plate as a wrench to unscrew the barrel.

The safety is a small button located near the trigger guard. The magazine release is a small lever located behind the magazine. The weapon is modular and allows for many customizable components from ZiPFactory to be used.

It works best with BX-1 round rotary magazines and has issues with using the BX round magazine, which feeds too slowly. The extremely small and light polymer bolt cycles very quickly, which causes aftermarket magazines to fail to feed or double-feed, only exacerbated by the weapon's lack of a feed ramp.

The bolt can also often slam shut on a casing that has only partially exited the weapon, causing a stovepipe jam. The high bolt velocity also causes occasional case ruptures due to the bolt attempting to extract a case while pressure is still high enough to rupture it without the support of the chamber, causing serious jams. The lack of an extractor and an ejector means that the weapon has significant trouble with extracting and ejecting a spent casing, further contributing to firearm failure: it also means the ejection angle can vary wildly, with the weapon sometimes shoving a hot case directly into the shooter's trigger finger.

In addition to its unreliability, the use of the two charging rods placed so close to the muzzle was very unsafe, particularly when using the restrike rod with a chambered round which has been known to cause the gun to fire without the trigger being touched. Many users also found the restrike rod was still quite capable of ejecting a chambered round either partially or entirely, with the former simply jamming the gun.

It was also notably difficult and counter-intuitive to disassemble. Its ergonomics are usually considered to be awkward, particularly for shooters with large hands.
