I have recently purchased a NIB G3 (photo enclosed). The receiver is marked G3 FS. I am confused in that it would appear (or possibly I am confused) this designation is for a non-full auto weapon, whereas the rifle clearly has a "SEF" trigger group. I am also not familiar with the small lever and the adjustment screw just behind the trigger. This is a H&K weapon made in Germany in 1978. Any help will be appreciated.
