Instead of reading usless babble and opinons that are NOT backed up in fact lets look at something from the ATF website:
http://www.atf.gov/firearms/faq/faq2.htm#b1"(B7) May a nonlicensee ship a firearm through the U.S. Postal Service?[Back]A nonlicensee may not transfer a firearm to a non-licensed resident of another State.
A nonlicensee may mail a shotgun or rifle to a resident of his or her own State or to a licensee in any State. The Postal Service recommends that long guns be sent by registered mail and that no marking of any kind which would indicate the nature of the contents be placed on the outside of any parcel containing firearms. Handguns are not mailable. A common or contract carrier must be used to ship a handgun."
Simple and the the point,NO REQUIRMENT for a FFL on sellers end,FFL required on buyers end.
There is NO reason for FFL to be used on sellers end.If you have some case where a 01 FFL was sued for transfering a faulty firearm POST IT.
The choice is clear,facts "straight from the horses mouth" or opinions and fairy tails and stories straight from...well the other end of the horse !
