Before somebody tells me to "google it" or "use the search function" - I did, and found conflicting reports. I want to clarify once and for all from people who know, exactly how much of my personal information is tied to a FFL gun purchase. My questions are as follows:

#1: I understand the gun's serial number is attached to the info sent to CBI, correct? Regardless of what they "unofficially" do, is there a publicly acknowledged database linking that serial to me, beyond the FFL's "bound book"?

#2: Since one background check is good for several guns at the time of purchase, do all the serial numbers need to be attached, or can just one go to CBI?

Thanks guys.
