I’m sure there are plenty.

The finer detail though is that any FFL with a table still has to run a NICS background check. While any non-FFL doesn’t (and to my knowledge can’t even if they wanted to), which is exactly the same as if they were selling privately in any other way.

So, it is true you can buy a gun without a background check at a gun show, but it’s not like it’s a special law free zone where FFLs suddenly are exempt from the rules. It’s a unique situation where businesses and private sellers are selling guns right next to each other, each following different legal requirements.
