...they will then know who is supposed to currently own that gun by the serial number...
The feds already have that in place with the form 4473.
It was established under Clinton and he promised that they would only keep those records for 30 days.
They have the serial number from when it was purchased new from a FFL holder when a background check was done on the purchaser. They don’t know who is supposed to own that gun if it is then subsequently sold by the private owner to another person. After July 1st all gun sales/transactions of guns bought from a FFL holder will then require a background check any time that gun is sold/transfers ownership. To my understanding the serial number will be tracked along with the person who passed the background check and is supposed to now own the gun.
This, along with mandatory reporting of lost or stolen firearms seems to be registration to me. Seems like they will know the serial number and who is supposed to own that gun.

Yes they would keep the original records for 30 days but no law said that they couldn’t copy them. Said a friend in the business
