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). - SPECS - 30MM TUBE - ENGRAVED RETICLE WITH DUAL ILLUMINATION - LOCKING TURRETS (PUSH-PULL) - PRECISION 1/8 M.O.A.
