No other serious scope offers that very important powerful advantage. *They are manufactured from a one-piece forged body. *They have a ¼ MOA adjustment for windage and elevation with truly amazing anti-backlash repeatability. *They come with a patented zoom gear system which provides the smoothest, most reliable movement through the full zoom magnification range. *The rangefinding reticles are etched into the glass lens providing superior strength compared to scopes with wire reticles. *New side focus replaces adjustable objective (A.O.) and repositions it to a very shooter friendly location (scope saddle).
