Yep had an issue with one of the rivets myself. Man, I had to take a dental pick to hold that damn spring on the bho while fooling with the axis pin. Tapped the gas block off of mine yesterday and went to .093 on the gas ports(they were about .060 on a good day), enlarged the gas block where the ports reside, profiled the hammer and it runs like a champ. Good to see its successful. Once its converted right, you'll never look back. Take it out and do this to it: http://www29.zippysh...62855/file.html
