Hijacking the thread, but just a curiosity question, and I'm asking hypothetically, not because I have any ulterior motives:
What would happen if a person wrapped a handgun in bubble wrap, put it in a priority mail box, and shipped it through the postal service? I'm assuming if it were found out, the person would be in trouble - but is there any mechanism to detect that something in a box is a firearm as opposed to a machine part, or are we all just on the honor system there?
Disclaimer: I have never shipped a handgun, and if I did, I would go through an FFL. I have shipped a rifle before (for repair) and followed the instructions given, and received it back with no issue.
I'm really just wondering out loud is all....
