Aimpoint 11972 CompM4 2 MOA ACET System Passive Red Dot Collimator Reflex Sight Description: The electronic components in the CompM4 make stronger upon Aimpoint s existing stateof- the-art ACET diode circuitry, allowing this sight to run constantly for over 8 years on a single AA battery. The CompM4 features an internal voltage regulator that allows the sight to operate on any AA size battery available around the world. This sight features a 2 minute-of-angle (MOA) dot size, making it perfectly suited for use with Aimpoint 3X Magnifier scope module. The CompM4 is optimized for use with all generations of night vision devices, and features an extremely rugged and easy to use 16-position manual switch with 7 night vision compatible settings and 9 daylight settings. The CompM4 sight body is designed to give protection to both the optics and adjustment components against hard use, and is waterproof to 45 meters (150 feet). The CompM4 also features an improved QRP2 Picatinny rail mount, eliminating the need for a separate mounting ring. This mount has over twice the clamping force of the original QRP, and features a lower and wider torque limiting knob to make stronger ease of use and lessen the chance of the sight base becoming snagged on other equipment. The mount is keyed into the sight to absorb recoil forces. Vertical and cantilever spacers are available to allow the sight to fit on all rifle and carbine variants. The sight can be used on any other weapon with a Picatinny rail mounting system.
