The 3-15x50 M5Xi Military Riflescope by Steiner Optics is a precision-engineered instrument suited to mid-range shooting. The fully multi-coated optical system features a 50mm objective for gathering more light in very low light conditions and 3-15x zoom for target acquisition. Broadband anti-reflective coatings assure greater than 94% light transmission for optimal performance in low-light conditions. The glass-etched Horus Tremor 2 illuminated reticle features seven night and four day levels with "off" positions at each end, and quick standby levels between each for fast return setting. The tube and knob configuration are optimized for more mounting options and optimum performance with different rifles and added equipment. Precision 0.1 mil impact point adjustments for windage and elevation are accomplished with tactile click-by-click feedback. Parallax can be adjusted from 25 yd to infinity with the side-mounted knob. The scope features one-piece aluminum tube construction and is waterproof to 33' and fogproof.
