Overview
I want to know if there is a way to make a functioning gun in people playground. I have only managed to make piston and explosion powered guns, all muzzle loader, though I have attempted to make a gun with a mag, although it is a gravity powered one. All in all, I just want to know some gun making ideas from other people who may or may not have attempted or maybe succeeded in making a gun.
