Dominate the battlefield with Trijicon's 3.5x35 Advanced Combat Optical Gunsight (ACOG). This battle-ready optic will help increase the success rate of your mission while withstanding the most hostile environments and adverse weather conditions. It is built as a ruggedized riflescope for close quarters combat (CQC). Its optical system is optimized for the cause by giving you a notable 3.5x magnification with a 35mm objective lens. The fully multi-coated optics, manufactured from high-quality optical glass, are designed to improve light transmission, reduce image distortion, and deliver the best possible visibility in most situations. For engaging targets quickly and accurately, this gun sight is equipped with a brilliant green .308 Crosshair reticle that offers an LED-based illumination system and brightness control. To help you manage wind drifts and ballistics, the scope has 40 MOA windage and elevation adjustments with a 1/2 MOA impact point correction.
