Konus Armada 6-24x 56mm Riflescope, 30mm Tube 7166

While the average parallax wheel will simply provide an estimation about a given distance (200 m/yds will be anything between 190 m/yds and 210 m/yds) the exclusive system of the Armada models is spot-on and flawless with every single measurement instead (200 m/yds will be 200 m/yds, with the same precision of a laser rangefinder).
