You can send it registered with a return receipt. I bought (attempted to anyway) a $700 Leupold this way and the guy tried to screw me by shipping some wood ballast insured instead of the scope then he was going to claim a loss as a result. When I was done with him in 24 hours, I had my money back Express Mail, knew where he lived in TX, knew who his neighbors were, how much he paid for his house, how long he lived there, how much his taxes were, where he worked, who his supervisor was and shortly there after the Postal Inspector had him under arrest for mail and insurance fraud. Out of hundreds of I-net transactions, this was the only time someone tried to screw me and I was suspicious all along so my gut feeling paid off. THe little fxxk was quaking big time when I was done with him. BTW the deal was from a Sniper web site, not AR15. I've bought mags & other stuff here without problem so if it's something small $100 +/- don't sweat it too much unless you have reason to be suspicious.
