Specifically designed for precision long range shooting, the Phenom 5-30X , the High-Lux Phenom 5-30X is a first focal plane scope featuring the illuminated CW-3 reticle. The CW-3 reticle enables the operator to quickly place follow up shots by tracking the first shot using the various reticle subtensions. As the Phenom 5-30X is a First Focal Plane scope, the CW-3 reticle can be used for holdovers at all magnifications. By utilizing the Christmas tree portion of the reticle, all windage holdovers can be made on by holding over. Save your internal adjustment for dialing elevation! From designing the optical system to eliminating optical shift when changing magnification, the Hi-Lux manufacturing process requires meticulous attention to detail and precision. All glass lenses in the rifle scope are fully multi-coated with DiamondTuff14 for optimal light transmission. Combining the solid 34mm aircraft grade aluminum tube with the Phenom’s large 56mm objective lens maximizes its light gathering capabilities. Nitrogen purging and rubber gasket seals guarantee fogproof performance in all temperatures and climates. When competing in shooting competitions, you need to maximize every advantage you have. Designed and tested by former military operators and professional shooters, the Phenom 5-30X is a rugged, yet precise instrument, dedicated to tearing up in the competitive circuit.
