-------------------------------
When mailing I had to find and print the regulations online and take them with me to the post office. I never bothered talking to the person at the front desk, I asked for the postmaster and told them exactly what I was doing. The peon's at the front desk ended up calling the post master anyway and trying to educate them was an exercise in having the same conversation twice.
My experience with FedEx and UPS for long guns left much to be desired, so even though tedious I used the Post Office. Handguns on the other hand I was forced into using UPS.
Hope that helps.
