Was shooting my AK on the weekend and I never sighted it. At 50 yards it was shooting about 3-4 inches high and 3 inches to the left. Thinking about purchasing a sight tool to zero this in. I read an article about sighting it in however it didnt tell me how much adjustment = how many inches at 25/50 yards. What is a good ballpark figure to use for elevation and windage adjustments?
