well you have to keep files and forms like any other FFL that sells to people. Fill out the 4473 and file it. And I don't think it really entitles you to start acting as a retailer of sorts to the public. No problem shipping stuff to other licensees when you get a copy of their FFL. I myself would not mess around selling much to individuals as if the ATF notices you are selling lots and lots of guns to non licensees they would maybe require you to get a regular FFL or worse. What do others think
