Launched 2007High or low battery compartmentThe CompM4 series of sights are available in two versions: The CompM4 offers a high battery compartment. The CompM4s offers a low battery compartment. In all other aspects, the Aimpoint CompM4 and Aimpoint CompM4s are identical. Aimpoint presents their 2 sights separately on their website as they do look different. Designed for 3rd generation night vision technologyThe CompM4 sight can also be used by hunters and sport shooters who need night vision compatibility. The performance of CompM4 sight is optimized for use with all generations of night vision devices (NVDs), but is ideal for 3rd generation night vision technology. The clearest, brightest image possibleAimpoint’s unique coating on the front lens reflects the dot’s selected frequency of red light at near 100% efficiency to give the highest possible dot brightness with the least amount of energy while other wavelengths in the visible and near-infrared part of the spectrum pass with a minimum of reduction. This provides the clearest, brightest image possible when used with a 3rd generation Night Vision Device (NVD). Ready for use around the clockWith 7 NVD-compatible brightness settings and 9 daylight settings including one extra-bright setting, the CompM4 sight is ready for round the clock use.
