There is no gun show loophole. Way back during the Clinton administration I went to a show and nope, I had to get a background check. Bought a cheap rifle. It was so inaccurate I had to sell it. Worse than useless.
All FFL have to run checks on their customers no matter where the gun is sold.
WE know that but it doesn’t stop them from saying it. Now, I got a couple F-15s at a reasonable price......😁👍
