The term "G series" is often used to describe what I call the "amnesty G" guns. Those are the guns which were exempted by serial number by court decision. THey were allowed to be imported and then found to be identical to the selective fire versions except for the selector. There are lots of FAL rifles that have G prefix serial numbers that are not like that and it seems that they attract novelty attention because of the G serial number, but they are 100% semi auto rifles. Not all the Browning guns were brought in for/by Rogak. I have a type 2 Browning import gun that is marked "EJK DEVCO, TX" which was imported by Ed J Kline of Houston Texas in the Early 70s.
