The Pinnacle of Optical Performance. The V8 2.8-20x56 opens up more opportunities at low light. The 20x zoom and optional BDC-H or BDC-S bullet drop compensation also make it excellent for long-range shooting. Minimal sub-tension and noticeably higher accuracy, even at long distances and in the dark. The V8 2.8-20x56 features an external elevation turret with BDC (ASV) with ballistic rings, .33 MOA turret adjustments, side parallax adjustment, and illuminated reticle #43. 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 ZEISS 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 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, further confirming that ZEISS quality standards are achieved.
