Yes, Jeff is right. But I had a weird experience at my local PO. I sold a rifle at an on line auction and was shipping it to a FFL. When I got to the line the girl at the counter looked at the address and said loudly "this isn't a gun is it?" I looked around and it seemed like time stopped everyone stared,and you could hear a pin drop. Thinking slightly faster than a turtle, I knew I had disassembled it so that I could use a smaller box and I replied "no" it's just parts. I have no idea what level of hysterics she might have gone to if I had answered otherwise! Don't make a big deal out of it, lots of folks loose guns that way.
