I'm trying to set my K80 to the factory 70/30 POI position, I've searched on the web but can't find the marking it should be set on the actual rib. I have a 07 model K80 with the high adjustable rib, its not a pro-rib.. The adjustable comb is all the way down. Lets say I set the rib where the dot is in the the adjustment hole, it looks like I can either put the dot high or low in the hole its never centered.. What would that POI be if lets say the dot was in the high position of the hole? Thanks..
