Has anyone had experience with working the SKS grenade launchers? I need to know what is the correct way to turn the knob to shut off the valve... Thanks

When viewing from normal sighting position, the valve should be to the right for semi mode. Turn it to the left to the straight up position for GL or as some call it, single-shot mode.

By raising it up, it also makes raising the G/L sights up. On my SKS, it kinda blocks the G/L sights.
