I renewed my C&R last month. As to listing acquisitions/dispositions, they only ask for the numbers, for example: 10 acquisitions, 5 dispositions. And this applies only to weapons acquired with your C&R. They do not ask for any details such as serial numbers, from whom you bought, etc. The C&R is a good deal even for a casual collector. As long as you abide by the rules, you shouldn't have any problems. HTH
