I would agree that they want it back to find out what went wrong with there process. If it was a common problem they would probably say don't worry about it and go on, but if its rare they want to check it out and see it. I would highly doubt they will give you the trigger info you want. Most CB makers warn against messing with the triggers. I would say they do not want to give you the trigger info out of fear you put it back together wrong, then the bow fails and you sue them, its what Americans do in this day and age.
