My experience is just what Jonesy said. In both cases I was involved in, only one of which was a gun part, UPS paid off in full and took the goods.

BTW, with a gun, the carrier still has to adhere to a federal law regarding transfer of ownership. As such, they may elect to pay for damage repair or completely pay off and let the shipper keep the gun. I have not had a claim on a full gun, so I don't know for sure.
