The SpecterOS™ 4x is a rugged lightweight optical day sight (LDS) designed for 5.56 NATO standard light arms (e.g. SA80, C7, M4). The SpecterOS™ 4xLDS by ELCAN utilizes the superior optics and mechanics of the commercially available SpecterDR. The SpecterOS™ 4x is a fixed 4x magnification optical sight with a large exit pupil and long 70mm eye relief. Superior situational awareness is achieved due to the ultra wide viewing angle and unmatched viewing in low-light conditions.
