Some FFL's(gun dealer) will take a shipment from a non FFL, but not all. Easiest way is to go to a local FFL and have them ship it to the FFL that buyer is using to do the transfer. They will over night it for you. But your local FFL will need a copy(fax or e mail copy) of the buyers FFL before they will ship it
Also I agree with the numbers on the value above, saw one sell about three months back at a local auction go for about those numbers.
