A zip gun is a common example of a homemade, ‘improvised’ firearm. Typically, a zip gun will use a rubber band to force the firing pin, igniting the projectile through a thin metal pipe. [1] X Research source Though never near as effective (or safe) as professionally crafted guns, a zip gun isn’t too expensive to make, and can be all done at home.

    About This Article

    To make a zip gun, you’ll need a steel tube, wood board, solid pipe plug, 2 pipe couplings, 2 elastic bands, a metal strap, 2 screws, and a flat head nail. Start by drilling holes big enough to fit your ammo into the pipe and couplings. Next, drill a small hole in the center of your plug, push a nail through it, and file off the other end to secure your bullets in the loading chamber. After you’ve finished filing the nail, saw your wooden board into pieces to fit around the pipe and the stock. Once you’ve glued these together, screw your front coupling to the front of the gun and the rear coupling to the back. Then, screw in the pipe plug. To make a firing mechanism, bend a metal strap into a U-shape, drill holes in the ends, loop it over the gun barrel, and screw it to the stock. Finally, attach your elastic band to each side of the strap and stretch them to the front coupling. For more tips, including how to load and fire your zip gun, read on!

    Closely associated with ‘juvenile delinquency’ of the 1950s, ‘zip guns’ were often fabricated by youngsters who could not afford to purchase or were forbidden from owning the genuine article. A mechanically inclined youngster might upon obtaining ammunition, most often widely available .22 rimfire, find that such rounds will fit into a section of suitably sized steel tubing, often a section of the salvaged car radio antenna. From then on it is a simple matter of fabricating a means of striking the rear of the cartridge while ensuring the entire assembly is held firmly together.

    Such weapons, while being extremely crude are just as capable as inflicting a lethal injury upon a close target as a conventional pistol. Due to bullets tumbling due to lack of rifling, injuries inflicted can potentially be worse. Because of their ease of construction and requiring no tools or expenses, knowledge of how to make zip guns quickly spread from street gang to street gang culminating in fairly standardized designs being adopted. Zip guns would sometimes be produced as a group effort, often making use of a school workshop resulting in better precision and reliability through the use of superior materials and machine tools.

    The Original Ghost Guns

    Although most of these may be extremely crude, such zero-cost disposable pistols became a serious concern for authorities at the time, often being used to seriously injure and sometimes kill. The emergence of cheap commercially produced handguns may have contributed to the eventual fall in the number of improvised weapons being encountered towards the late ’60s, perhaps coupled with the decline in creative hands-on skills of teenagers.

    One of the most common (and reliable) methods of constructing a zip gun is to attach a door bolt to a wooden handle having a barrel made from a section of steel tube securely taped to it. Elastic bands are tied around the handle of the door bolt to act as a striker. The weight of the heavy door bolt behind the cartridge prevents it from flying back too fast and rupturing upon firing, a factor adding to the user’s safety. Where commercial ammunition was difficult to obtain, a common method was to obtain .22 starting pistol ‘crimp’ blanks and combine them with an airgun pellet to produce a round with similar power to .22 short.

    A .25 caliber zip gun recently seized by police harks back to the classic door bolt types of the 50s.

    Another simple model which according to police reports at the time began turning up in large numbers in New York City used nothing more than a length of car radio antenna, a nail, a rubber band and two pieces of tape. The large nail slides into the back portion of the antenna tube and the tip is filed to the correct shape to successfully set off a round of .22 rimfire. Alternatively, the metal shaft of a screwdriver may also be used, the chisel edge already being well suited. A slot the length of a .22 cartridge is filed across the middle of the antenna tube to allow loading of a round into the oversized front ‘barrel’ section. A heavy rubber band is cut and both ends are taped at the front of the tube, the middle looped around and tapped to the back of the nail head in order to provide enough force to strike the cartridge. When fired the cartridge often jams in the rear of the slot and will take impressions matching the nail and the tubing.

    Below is an FBI bulletin describing a similar zip gun which was seized in San Antonio, Texas in 1964:

    Another trend often employed was the use of a house key to serve as a hammer. The use of one is out of convenience as it requires little to no modification, already having a pivot hole in place and a suitable striking surface.

    Perhaps the most common type of zip gun is a modified toy cap gun. Usually, the barrel obstruction is removed and a section of car aerial tubing glued or taped in place as a replacement barrel liner. The hammer would be sharpened to a point and elastic bands wrapped around the front of the frame and hammer to provide enough power to fire off a cartridge.

    The excerpts below show that such crude weapons have none the less proven deadly on occasion:

    Zip guns in prison

    Being held in the most restrictive and controlled environment which society has provided, didn’t stop these inmates from fabricating potentially lethal firearms from innocuous pieces of scrap.

D is a 20 gauge shotgun pistol constructed from a bedpost and scrap lumber and was used during a prison break in which a guard was wounded and two inmates killed.

    Recently Improvised street guns have started to make a comeback. In a news report this month Winnipeg police reported that the number of improvised firearms seized went just from three in 2016, six in 2017 to over sixty last year in 2018. Many of these were reportedly made from bike parts. No matter how many new laws are enacted to restrict the possession of firearms, a criminal is just a step away from walking into a hardware store and assembling one of these.
