Theses days I was looking for a wheellock gun to use in a project, but I didn't found anyone. So I decided to make it for myself. This is an UNREALISTICK and NOT PRINTABLE anciente rifle, only for games and animations. This model has no functional internal components and isn't intended to be realistic or printable.
A wheellock, wheel-lock or wheel lock is a friction-wheel mechanism which creates a spark that causes a firearm to fire. It was the next major development in firearms technology after the matchlock and the first self-igniting firearm. Its name is from its rotating steel wheel to provide ignition. Developed in Europe around 1500, it was used alongside the matchlock and was later superseded by the snaplock (1540s), the snaphance (1560s) and the flintlock (c. 1610s).
