The SpecterDR 1/4x Optical Sight is recognized as the world's most advanced combat optical rifle sight. Effectively two rifle sights in one, the SpecterDR can be switched instantly from a 4x long-range sight to a 1x wide field-of-view CQB sight. Unlike sights with zoom mechanisms, both the eye relief and the optical design remain optimal. The battery-powered LED illumination system has two ranges: one that illuminates the entire crosshair for long range low light use, and another that illuminates just a red dot in the center for CQB applications. Zeroing functions are incorporated in the integral mount and the sight attaches to Mil-Std-1913 'Picatinny' receivers with ARMS Levers.
Many prefer the Elcan SpecterDR over models such as the EOTech 553 or Aimpoint CompM4 as they require pairing with a magnifier or the Trijicon ACOG as it requires an additional optical sight to provide 1x viewing. This allows a single, reduced weight optic with a minimal amount of rail space being utilized
