This design, designated as the CompM4s, features a low-mounted battery compartment giving the sight a lower overall profile, and placing the switch and battery compartment in a more protected position while preserving all of the outstanding features of the standard CompM4 sight.

The electronic components in the CompM4 include Aimpoint's Super ACET diode circuitry, allowing the sight to run constantly for up to 8 years on a single AA battery. All CompM4 sights feature an internal voltage regulator that allows the sights to operate on any AA size battery available worldwide. These sights also feature a 2 minute-of-angle (MOA) dot size, making them perfectly suited for use with Aimpoint's 3XMagnifier and Concealed Engagement Unit (CEU).

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 the optical and electronic components inside against hard use, and keeps the sight waterproof to 45 meters (150 feet).
