High or low battery compartment

To accommodate our customers, the CompM4 series of sights are available in two versions:

  • The CompM4 offers a high battery compartment. This is the product shown here.
  • The CompM4s offers a low battery compartment. Follow link to see the CompM4s.

In all other aspects, the Aimpoint CompM4 and Aimpoint CompM4s are identical.

We choose to present these 2 sights separately on the website as they do look different.

Complete and ready to mount

The CompM4 sight is shipped complete with a QRP2 mount and standard AR15 spacer. These sights also come equipped with a killFlash® anti-reflection device and MILSPEC rubber lens covers.

Integral mount

The CompM4 sight features an integral mount that eliminates the need for a separate ring, and can be customized with vertical and forward spacers to fit a variety of weapon systems.

Designed for 3rd generation night vision technology

The CompM4 sight can also be used by hunters and sport shooters who need night vision compatibility.

The performance of CompM4 sight is optimized for use with all generations of night vision devices (NVDs), but is ideal for 3rd generation night vision technology.

The clearest, brightest image possible

Aimpoint’s unique coating on the front lens reflects the dot’s selected frequency of red light at near 100% efficiency to give the highest possible dot brightness with the least amount of energy while other wavelengths in the visible and near-infrared part of the spectrum pass with a minimum of reduction. This provides the clearest, brightest image possible when used with a 3rd generation Night Vision Device (NVD).

Ready for use around the clock

With 7 NVD-compatible brightness settings and 9 daylight settings including one extra-bright setting, the CompM4 sight is ready for round the clock use.

Unique features of the CompM4

  • Low battery compartment
