I am trying to take the sights off my bow so that I can move my whole bracket. I just have one problem. I can't get the last bolt out that holds the bracket to the riser. I have twisted one allen wrench and bent another. I don't remember putting any loc-tite on the treads or anything. I am scared to put to much pressure on it because I don't want to break the head off the bolt. After all, I am going hunting this weekend but I would like to have my bracket moved before then. Any advise?
