It offers a magnification range of 5-25x in a 50mm objective lens that helps gain you an upper-hand in close quarters to long-range shots. It comes equipped with XD (extra-low dispersion) optical glass elements that help produce sharp, contrast images with true color retention, even in low-light conditions. An illuminated EBR-7C reticle placed in the first focal plane of the optical design maximizes the scope’s long-distance shooting and ranging abilities. For added convenience, an illumination dial with 10-level adjustment is integrated into the side focus adjustment knob for easy access.

High-Performance Optics

These elements are coated with XR Plus anti-reflection multi-coatings for increased light transmission and minimum glare on all air-to-glass surfaces, producing good quality images even in low light conditions.

The fully-illuminated crosshair subtensions provide precise aiming under low-light conditions.
