So I put a rifle up for sale and it sold and I have to ship it out of state. I've never shipped a firearm before so I have some questions. I do not have a C&R or FFL but the purchasing party has a C&R and of course the rifle I am shipping is C&R eligible. So when I receive a copy of the C&R license is that only for me to confirm that the address I am shipping to is legit or do I need to provide a copy of the C&R to USPS, UPS or whoever I choose to ship this rifle? I went in and spoke with USPS and they handed me a form to fill out that made very little sense and made it sound like I have to have a license to ship. Anyways who is the easiest to ship a rifle through USPS UPS FedEx? Is it me or the shippers liability if this rifle is shipped to someone without a valid license? Pretty much I need a step by step on how to legally ship to a C&R holder I don't want to get some little thing wrong and get fined/arrested whatever. Thanks in advance for the help.
