Thread: USA experience re registration

We had visitors from the states a few months back, nice guy but very 4th amendment mentality. He was gob smacked at our lack of rights, however he was at the same time fascinated with our system. He had never used a firearm with a suppressor.
I took him rabbit shooting and he got a total buzz using suppressed .22.
He was interesting to talk to. He buys raw gun parts like AR receivers that because they are unfinished they have no serial number.
He has a small mill in his garage and completes the milling and builds an AR.
He calls them Ghost guns because there is no record of them, reckons there's millions of them in the states.
