The electronic components in the CompM4S improve upon Aimpoint's existing state of the art ACET diode circuitry, allowing this new sight to run constantly for over 8 years on a single AA battery. The CompM4S features an internal voltage regulator that allows the sight to operate on any AA size battery available worldwide. This sight features a 2 minute-of-angle MOA dot size, making it perfectly suited for use with Aimpoint's 3XMagnifier 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 protect both the optics and adjustment components against hard use, and is waterproof to 45 meters 150 feet.

The CompM4S 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 improve 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 M16 rifle and M4 carbine variants. The sight can also be used on any other weapon with a Picatinny rail mounting system.
