Hi all, I bought me a J&J cue the other day and Its about 18.7 oz. I want to try and take the weight bolt out to make it close to 18 oz. I took the bumper off and the bolt that the bumper screws into, is that the weight bolt? I could not see anything else down in the butt. It is pretty much 18 oz with that out but then there is nothing to screw the bumper back into. I can take pics if need be, if I havnt explained it good enough. Thanks.
