So I buy a new VX-2, mount it and head to the range (after giving it a try at the "look thru the barrel" bore sighting). Bore sighting didn't work too well, 5 inches high and 3inches left. Make adjustments.....but wait, both turrets have a U with the --->, huh? Took me a little bit to figure out windage but I'm good to go now. 3 shots that you can cover with a quarter 2" high at 100 yards.
