2tonic,
Thanks! I thought the frame would be considered the firearm.

Unless you have not found a local FFL to do business with, there is NO reason to ship anything via any carrier yourself IMHO. My customers come to me to ship firearms for them, handguns typically are $25 unless you need $1000 insurance. I get the deer in the headlights look, not you. It's just silly simple to do and much cheaper than dealing with UPS or Fed Ex yourself.
