Re: How hard is it to sell a gun online?
Not hard at all.
I have helped handle several estates for local folks whose husbands died and left a lot of guns. They came into the PD and I was able to list their guns on Gunbroker.com and ship them out through an FFL, to an FFL. Never had a problem... and actually made a few friends in the process.
I will be glad to give you advice if you PM me. But the short version: Accurate descriptions... good pictures... and be willing to take ANYTHING back if buyer is unhappy. Some buyers are just never satisfied... smile, give them their money back and drive on.
And keep everything legal or even more than legal.... Ship out through an FFL even if it costs a few bucks... Ship to an FFL. It costs a little more, but worth it.
FYI, my friends in BATFE have consistently said that there is no specific 'number' of transactions that you have to make before you need an FFL. But if you start buying/selling a lot, you *may* end up crossing a non-existant line that noone can define. It is definitely best to work through an FFL.
