Slimmest Repeating Folding Gun
So far this is the slimmest design for a folding gun that repeats. A smaller one could be made but I'm starting off simple before playing the nanogun game. A nice bonus is that it doesn't have any blue rods sticking out so it is actually possible to fit it in your pocket if you're wearing big enough pants.
It fires. Decently depending. Has a 4 round oodammo magazine. I don't really care for the handle but it works. The way the bands are set up, it doesn't require a lock though it doesn't automatically unfold either. Just flip out the stock and it'll stay out then you pull down the handle.
Edit: Alright video up. This version fires oodammo.
