hey bud i know it can be Confusion adjusting these POI's..when you put your front shims in closiest to the receiver,Slide your stock over the bar, slowly keeping the stock and shims on,point your guns against floor, sliding the shim facing the cdx towards the butt end and the and you'll be reading csx at the top while facing the stock's butt,Remeber DX=righthand shooter,SX=lefthand shooter and so the markings have to be facing in the right postion ,if not
your gun will shooting crazy,so yes you should be reading CSX at the top...
