Here is exactly what the ATF 'Federal Firearms Regulations Reference Guide' (ATF P 5300.4) says:
(B8) May a nonlicensee ship a firearm by common or contract carrier?
A nonlicensee may ship a firearm by a common or contract carrier to a resident of his or her own State or to a licensee in any State. A common or contract carrier must be used to ship a handgun. In addition, Federal law requires that the carrier be notified that the shipment contains a firearm and prohibits common or contract carriers from requiring or causing any label to be placed on any package indicating that it contains a firearm.

So w/ the above stated, can I ship a hand gun directly to a buyer who is within my state w/o the reciever being an FFL?
