I stand to be corrected on this as it is a while since I have done it.

After getting paid, you fill out an Dept of Defence export request and they will issue it within about 2 weeks.

The US buyer has to find a dealer who is a registered importer
and a Form 6 is filled out and sent of. Wait 6 wks to 2 months for it to be returned.

When you have a copy the item can be packed up and sent to a freight forwarder for shipment to the US. I would suggest use someone who is used to shipping guns to the US.

Pay freight forwarder and off it goes.

Note - Import duty may be payable by the importer / buyer but since the gun originated in the US this MAY not be the case.

Also, call Butch Searcy and see if he wants it and finally,

Why not try to sell it here ? I get calls all the time asking if any
of my guns are for sale.

Hope this helps. PM me if needed and we can talk over the phone
if you want to call me.
