I think this thread should be stickied but thats just me.
I think the skorpion is a wierd exception to this rule because its size doesnt change much with either type
iR4WR, I don't think you quite understand. When a small gun is modded to a big gun, it turns small, when a small gun is modded to a small gun, it turns small. But when a big gun is modded into a big gun or a small gun, it will turn out big, both of them.
