Has eight magnification ratios, including the highest magnification ratio in the first focal plane (FFP) configuration rifle scope made to date. The mrad reticle scale value remains constant across the entire zoom range. It is easy to range the target without thinking where to set the zoom range. Additionally, with the capability to set any position as the zero point in elevation (0-set device), the shooter will never lose his starting calibration. This scope was designed to eliminate optical aberration without compromise, utilizing high-end extra-low dispersion (ED) lenses.
