The Night Vision Sight, Individual Served Weapons, ANPVS-4 is a portable, battery-operated, electro-optical instrument used for observation and aimed fire of weapons at night. It uses the low light level illumination of the night sky, i.e., starlight, moonlight, reflected from the object and its background to form an erect, clearly defined image. The sight can be mounted on the M14 and M16A1 rifles M14, M16A1, M60 machine gun M60, M67 recoilless rifle M67, M72A1A2 rocket launcher M72, and M79 and M203 grenade launchers M79, M203. The sight is passive in nature. The sight consists of the main housing, objective lens assembly, range focusing ring, illuminated sight reticle, with azimuth and elevation adjustment knobs, eyepiece assembly with rubber eye shield, and eyepiece diopter focusing ring, image intensifier assembly, and an objective lens daylight cover. The sight has controls for increasing or decreasing the brightness of the reticle and the image intensifier assembly.
