I know, I bought the DVD this weekend and sat going through it in stop frame. I was just saying that in this "real" version, the bottom part is just a shotgun. I know in the movie it was a grenade launcher. I have decided to redo the model for myself, and when it is finished if anyone wants to use it for animation I will just e-mail them the file. The new version will work just like the movie one. I didn't think that anyone actually did animations anymore, so I didn't think anyone would actually be interested in the moving features. I will fix them up.
