How to ship firearm for warranty work?

Any shipping hub csr will know, by the DANIEL DEFENSE label it's a firearm. I always tell them what it is, primarily for ins purposes.
You can split upper from lower to pack easier. there's no need for adult signature since it's going back to mfg. Your tracking label is documentation they received it. More than likely you will need to sign when returned from DD.

Make a copy of the return label this is your info besides tracking, that you need for info if and when you need to contact DD after they've had it 2-3 weeks.
