The ATF has nothing to do with the NICS check, that is handled by the FBI..... on the other part you are correct thoughATF only gets your personal information and what type of firearm it is: ie: longgun or pistol. Information stays with the dealer and may be given to ATF if they have reason to look at the owner or firearm
I understand your concerns, and I tend to agree by not putting to much "good faith" in our government. So I simply try to make an effort to make my purchase through FTF transactions "just in case." Not always, but I buy it up quick if I find a deal and this usually keeps me from buying in stores and their prices.
And yet you post information like this on the internet
Happens here every day!
My favorites are the CCers who disdain OC or even telling others they OWN firearms yet they have their name and pictures of all of their guns online and where they carry and how...
