the commas.... take away everything in between the first and last commas...."It shall be unlawful for any person knowingly to deliver or cause to be delivered to any common or contract carrier for transportation or shipment in interstate or foreign commerce, to persons other than licensed importers, licensed manufacturers, licensed dealers, or licensed collectors, any package or other container in which there is any firearm or ammunition without written notice to the carrier that such firearm or ammunition is being transported or shipped"
It says if you ship "to persons OTHER than......licensed dealers (i.e. FFL Holder)." So if I decide to send it to an FFL holder via Ground I don't have to declare anything. That may be against the carrier's policy of "Overnight" but I can sure choose to do so. It'll just be at my own risk with no insurance payout.
