The EOTech® Vudu® 1-10x28mm Rifle Scope with SR5 Illuminated MRAD Reticle is a robust 1-piece rifle scope built around a virtually indestructible aircraft aluminum tube with a corrosion-resistant anodized finish for long-lasting service in any tactical shooting application. The monolithic eyepiece allows for smooth changes in magnification, and the included throw-lever offers lightning-fast changes in magnification when engaging targets at varying ranges. The illuminated, glass-etched MRAD reticle offers quick target acquisition and rapid distance estimation at any magnification and lighting condition, while XC™ high-density glass lenses maximize light transmission for superior edge-to-edge clarity and optimal resolution. Low-profile tactical turrets lock in place for maximum zero retention and offer quick reindexing. Better yet, this scope features simple push-button illumination controls, allowing you to cycle through the 10 user-selectable brightness settings in a flash for optimal clarity in daylight and low-light environments. Operates on one CR2032 battery (included). Includes a 2-hour auto-off feature for superior battery conservation.
