The reason I ask is that I bought a barrel blank, the box arrived with a hole and no barrel. I submitted a claim with the USPS because it was insured. They denied the claim, stating, " Pistols, revolvers, and other firearms capable of being concealed on a person can only be mailed between authorized dealers as stated in 18 USC 1715."
This was a 26-28' unthreaded, unchambered barrel blank! ***? Of coarse I'll file an appeal, I just want to get my facts straight first.
