Hmmm.... How about a sniper rifle
ONI, man, why not make some form of highly German heavy machinegun type bit (a dose of MG3 thrown in for good measure), but utilize all sorts'a scifi bits n' bobs in it's creation and deployment.
It's a lovely gun though, very "slim".
I didn't know there was a software called Pimp My Gun! It certainly works well, though.
It's kind of a "game/online tool" for making guns out of the parts of other existing firearms. I made one the other night while I was bored and decided to paint over it and reshape it today.
