I have just fitted a MTC connect 3-12 x32 to a aa s400. it is in low mounts and its centre point sits about 1.5 inches above the centre of the barrel. It came off a EV2 where it was fine with roughly the same positioning relative to the barrel. Trying to zero and the horizontal is perfect but the verticle is 3 mil dots low and the up down turret is at its maxium up position. What do i do?
