I had two guns needing repair a smith ar22 that started going off full tilt and my montado that blew the front blade off. Smith sent me a fedx lable for the ar so i figured i might as well use them to send the handgun to ruger. I thought they were suppose to go by air but the lady filled the tag out and told me 12 bucks and it would be there by friday via ground. I didnt say anything but wondered if she just didnt know the rules. Im a bad boy and often send in gun in flat rate boxes through the po even though its illegal but if this is the case why take the chance.
