ok, so today i brought the gun into silver bullet and had there gun smith look at it. come to find out, since the bull barrel is so heavy they drilled out the butt stock and put a steel bar in there to counterweight the gun and that happened to be moving around. He said i could take it out and not have to carry it through the woods or leave it in if it doesnt bother me cause its not affecting anything! so that was a big sigh of releif for me!
