It has been a while since my shotgun was stolen by the post office.
I do not remember if I had to mention what it was when I shipped it or when I filed the claim.
If the shipping part does not ask what it is, then fine. Just make sure you followed all regulations that are in the book.
If you ever make a claim, more than likely it will get denied because it is a gun. Then you will have to reclaim showing them their own regulations.
But if you followed all regulations, they will pay.
Hope you never have to.
That said, you are supposed to tell UPS driver also, but I have not done that. Do not know what would happen during a claim since I have not lost one with them yet.
chances are that it will get there. I'm just stating what may happen if it does not.
