A buddy told me today he ran across a web site where some sellers (apparently private parties) were selling firearms directly to buyers in other states, without going through an FFL. We were both pretty sure the seller was violating one or more federal laws, but we didn't know if the buyer was also violating any laws. Does anyone know the answer? And no, I'm not thinking about doing it (in fact my buddy sent the seller an email directing him to the ATF website), but I am curious.
