I have some rifles on sale here and with the scamming that's been going on I've had a couple of people ask for specific pictures, etc to verify I'm legit. I was not in the least bit offended, actually expected it and understood the reasons behind it. I'd hate to be scammed and would ask the same question if I was interested in buying from a private seller. So ask the questions of those sellers you're interested in buying from for your own peace of mind, make sure (as much as possible) the seller isn't a scammer.
