This fixed 4x prism scope features battery-free passive red fiber illumination, which harvests ambient natural light to power the reticle without batteries. It uses multi-layer green coated optics to boost light transmission and cut glare, delivering distortion-free bright sight pictures for fast target tracking. Separate textured turrets enable precise windage and elevation zeroing for consistent shot accuracy. Built with a solid one-piece aluminum alloy body and integrated bottom mount, it holds zero firmly against shock and vibration. An extra top Picatinny rail lets you attach extra optics or accessories for customizable setup.
