Our local UPS Store WILL NOT touch a gun or gun part, but our local "hub" will ship anything. Our local USPS will ship ANYTHING. I had an experience trying to send a gun stock (laminated piece of wood)back to the manufacturer. Like someone else said, it was like trying to ship a bomb through the UPS Store, but I walked directly across the street to the USPS and mailed it, and the rate was LESS than UPS. I only use USPS now.
