I've had better luck with FedEx than with the local ups hub.
The ups lady likes to make up her own rules like demanding to see the recipients FFL and inspecting to make sure the gun is disassembled.
I set up a personal FedEx account and print off the shipping label at home, then just drop it off at the service center.
