Zipguns are rudimentary bullet cannons that usually consist of little more than a pipe which acts as a the barrel, and a hammer or pin to strike the end of the bullet to ignite it.
Zipguns are fairly inaccurate, but a bullet to the face is still a bullet to the face, so they can be useful and deadly in close combat.
