Is there a limit on how many guns I can sell privately and not get into trouble for not being an FFL? Is there a number per time frame? or anything at all? Say I sell 10 old guns I havent' used in years, or I get a good deal at an auction, are there any differences in the two? I see guys on here selling multiple guns, so I'm guessing it's not too big of a deal, but I figure there is some kind of a limit.
