Improvised firearms
Extracted from the Wikipedia article Improvised firearm.
Improvised firearms (sometimes called zip guns, pipe guns, or slam guns) are firearms manufactured by an entity other than a registered firearms manufacturer or a gunsmith. Improvised firearms are typically constructed by adapting existing materials to the purpose. They range in quality, from crude weapons that are as much a danger to the user as the target, to high-quality arms produced by cottage industries using salvaged and repurposed materials.
