cumbersome gun

I tried to think of what would be the most inconvenient, rediculous design for a gun, just for fun. This is what i came up with. I think my favorite part is the fact that for some reason it requires a hand crank. I think I may have been somewhat influenced by the fact that I have a miele vacuum, which has a rolling base, instead of a regular upright, like a hoover. And I'm always getting caught up in the cord and hose. So I guess this would be the weaponized equivelent.
I've been having a lot of fun lately just playing with basic geometry, mech and SciFi stuff is good for that. Back to basics, very theraputic :)

Also I thought i'd throw in a big dude with a teeny gun to offset the lil' guy with the big gun: okay, discuss...
