From what I understand about 6/3 detachable carry handle sights, one full clockwise revolution of the drum from the 6/3 position all the way around and back to the 6/3 position covers distances from 300 meters to 600 meters. Using the RIBZ sighting method, the shooter can adjust the drum so that there are six clicks below the lower 6/3 setting for closer range shooting. So from bottom-out position to the 6/3 setting there are 6 clicks and then a full revolution of the drum to get up to 600 meter range, where the sight tops out or maybe has an extra click or two left.
Well, I've got a UTG Pro carry handle sight, and it takes 16 clicks to get from the bottom-out position to the lower 6/3 position. Then I can make 2 full revolutions of the drum and have one extra click beyond that before it tops out. What's going on here?
