The Razor HD Gen II 3-18x is perfectly designed for long-range shooting that requires magnification and precision. The Gen II's High Density extra-low dispersion lens system is optically superior to the competition in clarity, resolution, color, light transmission and delivers an unparalleled edge to edge clarity. The generous eye relief allows for a heads up shooting style increasing situational awareness with dual-eye monitoring and split-second targeting. Adjustments shouldn't be a problem with the 34mm tube and the streamlined Zero-resettable turrets which feature plenty of travel per rotation. Illumination can be activated/deactivated between any of the 11 intensity settings without having to progress through the entire dial. Other convenience features of the Razor HD Gen II include a fast focus eye piece, large easy gripping turrets, and the ultimate convenience of the Vortex VIP Lifetime Unconditional Warranty.
