Burris' XTR II First-Focal-Plane Riflescope features cutting-edge technology that long-range precision rifle shooters demand. Multiturn target knobs with Zero Click Stop technology allow you to quickly and easily revert back to your original sight-in setting without counting revolutions. Ergonomic side focus and parallax settings ensure easy-to-reach adjustment and don't affect your shooting position. Rotary dial allows you to choose from 11 brightness settings to match the conditions and also features a battery-saver position between each setting for longer battery life. High-grade lenses provide impressive brightness and clarity. Index-matched Hi-Lume® multicoating improves performance in low-light conditions by minimizing glare. First-focal-plane reticle scales as magnification is adjusted, ensuring reticle subtensions stay the same regardless of the power setting. Waterproof, shockproof and fogproof. 1-8x24 model features the Modular Adjustment Dial (M.A.D.) System that allows you to choose from competition-style exposed knobs or capped knobs. Runs on one CR-2032 battery (included). 34mm main-tube construction. Burris Forever Warranty™.
