No paper for me, thanks. I'll gladly show id and answer any eligibility questions but that's as far as I go. I understand that being in a FFL's bound book for a particular serial #, one doesn't want it to fall into the wrong hands. But a BOS or even a GWL is not going to prevent that. If you really don't feel comfortable selling the item, then don't. Just MHO. In the end, its the seller's perogative to name requirements and the buyer's to accept or keep on scrollin....
