The Vortex Viper HD 3-15x44 riflescope features a versatile 5x optical design with a magnification range of 3-15x and a 44 mm objective lens diameter. Built on a robust 30 mm main tube, this optical instrument integrates an illuminated second focal plane Dead-Hold BDC MOA reticle system. The reticle uses customized reticle patterns to assist with holdover and windage corrections at various distances, particularly useful for hunting applications where distance estimation is required. The HD optical system employs selected glass elements for high resolution with minimal chromatic aberration, providing excellent color fidelity and sharp edge-to-edge imaging across the entire magnification spectrum. Light transmission is optimized for clear viewing under various lighting conditions. The outer lens surfaces are protected by Armortek coatings, which offer scratch resistance and durability in outdoor environments. The riflescope is argon-treated for waterproof and fog-proof performance, maintaining optical clarity in different weather conditions. A quick-focus eyepiece allows for rapid reticle adjustment, while capped windage and elevation turrets prevent accidental adjustments during transport or use. The construction is designed for field conditions with shock-resistant properties. This optical instrument is suitable for adult users engaged in outdoor activities that require precise observational capabilities. The black finish provides a professional appearance with minimal light reflection. With its 3-15x magnification range and 44 mm objective, this riflescope combines portability with optical performance for various outdoor applications.
