Zip Gun How to Make

A zip gun is a homemade or improvised firearm. Usually of crude design, they are most likely to be created by criminals or other persons not able to access conventional firearms. Most commonly they are single shot devices, but can sometimes be seen in multi-shot variants as well. Some variants are created to use regular bullets or ammunition, while others use pressurized air or other propellants to fire a projectile. Since by their very nature they are improvised devices, there is no one single "how to" guide, but check out http://www.weaponscombat.com/zip-pipe-and-pen-guns for more information on a number of methods.
