Konus 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). The scope features locking tactical turrets; fast focus ocular; parallax wheel for accurate measurements; ant1-canting bubble level and an adjusting range of 25mm.
