The Pinnacle of Optical Performance. The V8 NA 2.8-20x56 is specifically configured for North America and long range hunting. The V8 2.8-20x56 features an external elevation turret, .25 MOA turret adjustments, and illuminated reticle #60. The distinctly innovative optics utilize exotic glass types, from SCHOTT glass, consisting of multiple FL (fluoride) and HT (high-transmission) lens elements. The optical system yields an impressively bright image, with a guaranteed light transmission value of 92%. The exterior lenses are then protected from environmental abuse with ZEISSa (TM) LotuTec protective lens coatings. An immediate advantage of these designs is the extra-large and extra-friendly eye box that allows for faster target acquisition. The specialized optics are housed in a modern and compact 30 mm main tube design. The external elevation turret with ballistic stop adjusts clockwise for bullet impact down and counter-clockwise for bullet impact up. The opto-mechanical system has been torture tested to endure over 800 cycles of impact testing at 1,000 g-force and final tested to withstand multiple impact cycles at 1,500 g-force. V8 scopes are waterproof to 13 feet for up to two hours a " further confirming that ZEISS quality standards are achieved.
