Lots of folks don't know the rules. I've had to show the USPS what their own rules say about shipping long guns. Once had an employee tell me you can't ship any guns. Then the postmaster on site came out and said you can ship long guns, but I had to be a dealer (which I'm not). I told him I was shipping the gun to the dealer and here's a copy of the dealer's FFL. He grumbled and moaned like I was breaking the law, but finally relented. Amazing with as many guns as get shipped via USPS, that there own employee's wouldn't know what the rules are.
