Exposed elevation and windage turrets are low profile enough to stay out of the way in packing situations, but offer the quickness, ease and precision of dialing accurate shots at distance. A side adjustable parallax gives shooters peace of mind by removing parallax error from the equation from 10 yards to infinity.
