Re: Looking for a little assistance . . .
Getting them home...
One approach would be to find a FFL, on each end, and pay what they asked, to ship, and receive, across their books, each of these arms, which would likely be close to a grand, US, before you had them, in hand, and likely more, depending on UPS charges!
OTOH, If it were me, I'd simply take a few days off from work, enjoy the time off, and drive up to Montana, and haul 'em home, myself; no paperwork, no shipping, no transfer fee, and a wonderful, scenic trip!
