"The U.S. federal government has amassed records comprising over 920 million gun sales from the records of firearms dealers who went out of business, amid concerns alleging the Biden administration is seeking to create a federal gun registry, which would be unlawful."
Uhm...
That's been the law since the Federal purchase forms came into being decades ago.
Gun sellers hold those forms, but if they go out of business, those forms are to be transferred to BATF.
Given how far back those records go it's very likely that much of the information is obsolete.
