What is going on with UPS?

[Robert Redmond]

I believe it’s due to this rule they have now

UPS accepts packages containing Firearm Products for shipment only as a contractual service and only from Shippers who are licensed importers, licensed manufacturers, licensed dealers, or licensed collectors (as defined in Title 18, Chapter 44 of the United States Code) to authorized recipients, as outlined in the approved UPS agreement for the transportation of Firearm Products.

To transport packages containing Firearm Products, the Shipper must enter into an approved UPS agreement for the transportation of Firearm Products.

and possibly the person you ran into. Since the rules have been getting stricter, I’ve had better luck sending Registered or Priority Mail at a supportive post office, buying the label from Pirate Ship.
