The ELCAN Specter M145 Telescope is a fixed 3.4 power, 28mm optical sight that has been designed to engage targets accurately out to a range of 1200m. The optical sight weighs 681 gr and is extremely rugged for rough field conditions. The sight has an 8.2mm diameter exit pupil, which provides the shooter with excellent vision in low light levels, i.e. dawn and dusk. This large exit pupil also provides the shooter with rapid target acquisition. The long 70mm eye-relief permits ease of use on high recoil machine gun weapons.
