The AN/PVS-27 Magnum Universal Night Sight (MUNS) is a high-resolution Clip-on Night Vision Device (CNVD) that mounts on any MIL-STD-1913 rail in front of any existing scope. This adds night vision capabilities to daytime target acquisition platforms. The MUNS utilizes a full MIL-SPEC Gen 3 (autogated pinnacle) image intensifier tube, an extremely fast f/1.0 catadioptric lens for a brighter and sharper image in starlight, and patented permanent boresight alignment technology. The MUNS gathers twice as much light as the AN/PVS-22 Universal Night Sight (UNS) and can be used against targets at 1.5 times the range of the AN/PVS-22. The unit is installed, operated, and removed without tools and without affecting boresight (permanent boresight alignment).
The unit can be mounted on a spotting scope for long range reconnaissance, hand-held as a Night Observation Device (NOD), or used in other night-time operations requiring night vision capabilities. The MUNS is revolutionary when used with a high magnification fixed or variable power dayscope. The magnification is provided by the dayscope, which typically has much smaller optics than those associated with normal 4X or 6X night vision weapon sights. This means there is no loss in system gain or typical f/number loss associated with large optics. Variable magnification dayscopes can actually zoom in (up to 20X) and still retain the same gain with only a slight loss in resolution.
