Look at the rear sight ramp from the side of the rifle. The ramp itself begins at 1 and ends at 10. The setting behind 1 is a "shelf" that is higher than the beginning of the ramp. At the rearmost setting the rear sight leaf is set at a battle sight setting that is equal to the 3 on the ramp or 300 meters. Move the rear sight adjustment forward to 1. The battle sight setting is there for a quick sight setting that doesn't require seeing or looking at the numbers.
Despite some media reports, there were no AK-47s involved in the incident
