well ran into a snag. I got the arm attached but connecting the base to the suit proved to be a problem. Since my P2 armor is latex it is too flimsy for something of that weight and makes the cannon flop around to the point it wants to fall off. My roommate and I just spent the better part of 2 hours trying different ideas from wrapping string around it to mounting it on the back instead of the shoulder etc but came up with nothing that worked well enough. So at this point i'm open to ideas.
