I sold an AR on eBay waaaaaay back before they had all kinds of rules and shit.
Funny story, I packed it up and took it to the UPS store and when I insured it for 2 grand they asked what it is. I said its a gun. The guys all, we cant knowingly ship a gun insured like that. I said ok... Can I split it and ship it separate as gun parts? He was like uhhh I guess. So I opened the box in the store, and separated the stock and lower into one box with the upper and barrel in another and insured each one for a grand. The dude was tripping and probably didnt want me doing it right there but fuck I needed to buy the box from them anyways, I didnt have another one. There wasnt anyone else in the store so I figured why not. I'm sure I gave that dude the opportunity to tell a story or two in the future!
