And I’ve got a bridge to sell anyone who thinks they actually destroy those background check records once the sale is approved. Assume there’s a federal registry of every dealer purchase you’ve made since the background check went into effect.

I think if a FFA closes they have to send their records in to the Central Office.

... what kind of bridge?

Not every query results in a purchase - maybe the customer decided they want a different firearm, can't afford it, or other reasons. Also, the info submitted to NICS isn;t supposed to include the firearm being purchased, just a "longgun" or "handgun" designation. For TX at least, if you have a CHL they don't even query the system, you're an automatic go on that part. If the Feds do maintain those records, they certainly aren't close to being complete.
It's the stores that are required by law to maintain records of every FFL transfer they complete.
