Designed and built for precise long-range shots in extreme environments, the Vortex 4.5-27x56 Razor HD Gen II Riflescope combines superior optical and construction elements to produce a rugged scope for hunters and tactical professionals alike.

Engineered with a broad zoom range, an oversized objective, superior glass, and specialized optical coatings every optical component complements the other to provide clear and bright images at all magnifications and lighting conditions, especially when sighting a smaller target at extreme ranges on the highest zoom. The apochromatic lens is made of high-density (HD) extra-low dispersion (ED) glass to maximize light transmission, minimize distortion, and virtually eliminate chromatic aberration. All air-to-glass surfaces have Vortex's index-matched XR Plus anti-reflective coatings which are specifically formulated for the glass to which they are applied to minimize light loss and maximize image brightness, clarity, and color accuracy. This combination of coatings and optics, combined with its broad magnification range and MRAD-based ranging reticle and turrets, creates a riflescope uniquely capable of precise long-range shots.

An array of construction details protect the precision optics and enable the scope's use in the most extreme conditions. It is made of lightweight and durable aluminum alloy treated with a low-reflectivity and scratch-resistant matte-black anodized finish. The 34mm diameter one-piece main-tube is oversized for additional strength and maximum light throughput and allows for the wide elevation adjustment range that smaller tubes couldn't provide. It is filled with inert argon gas and O-ring sealed to make the entire scope waterproof and resistant to internal fogging when moving through extreme changes in temperature or environmental conditions. A 4" removable sunshade is included to reduce glare and prevent lens flare when pointing the scope in the direction of the sun.
