<Although, I'd still like to know how "required FBI background check", which I bet all are tracked and cross-referencable with the requestor, thereby giving a synthetic key to "gun purchase" does not translate to database of potential gun owners.> There are lots of legal ways to obtain a gun legally without a background check. Many states don't require a background check between private parties. More responsible folks will ask for a voter ID (to confirm residence) and or a concealed carry permit (to confirm that person may own a firearm/not a felon), but it's not a legal requirement. Same rules may apply at a gun show. Lots and lots of guns are sold this way. My first firearm was advertised online by a private party on a local forum, I met them in a parking lot, and paid in cash. I'd like to think I'm a responsible person, but I can certainly see how that system could wildly be abused. Each state has different laws, you can't do that everywhere. Also there are certain federally restricted items that require a background check (normally through a ffl). Things like short barreled rifles/pistols, silencers/suppressors, full automatic, etc. Different process for manufacture vs purchase, but in theory both are tracked with serial numbers and real ID's.
