I've had my BB for a week now, and loving it. when screwing the atty on though, it gets snug, but there is a gap between the bottom of the atty and the connector on the bb. I can screw it all the way down and it doesnt take any force to do it all the way. I just want to make sure I'm not hurting anything by screwing it down all the way. With it just snug, the atty wiggles around a little bit.
