The Pinnacle of Optical Performance. The V8 NA 2.8-20×56 is specifically configured for North America and long range hunting. The V8 2.8-20×56 features an external elevation turret, .25 MOA turret adjustments, and illuminated reticle #90. 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%.
