I worked with an old Vietnam vet. He told me a story along those lines. He said the guys were sending AKs back or something like that.I went to Vietnam in the mid-sixties and I heard that a guy couple bring his own sidearm to battle with him from stateside. And then they stopped the troops from bringing their own pistol. Back then a guy could ship back a gun captured in combat and apparently many were sent back. I was asked by a guy I knew fi I'd ship an AR-15/M-16 back in my Hold Baggage but I didn't want to go to jail for something I didn't own and this was 1967.
