Built to fit the demanding needs of precision shooters, the Vortex Razor HD Riflescope series comes fully optimized for long-range shooting. Featuring apochromatic objective lens system, HD glass, and XR fully multi-coated lenses, the Razor HD scopes deliver maximum light transmission and clarity. The optical quality is perfectly matched by the Razor HD's exposed tactical-style turret system with the exclusive Rapid Zero Return and Zero Stop, allowing the user to make adjustments in the field without losing their original zeroing. The Vortex Razor HD Riflescopes also offer superior durability thanks to a one-piece aircraft grade aluminum main tube and ArmorTrek scratch-resistant lens coatings.
