Aimpoint CompM4s

Aimpoint CompM4s – the US Army’s new M68 CCO

Aimpoint, world leader in red dot sights has a well deserved reputation for building brutally rugged and utterly dependable red dit sights which have become almost ubiquitous across the West’s militaries.  Aimpoints are incredibly robust, designed to operate in extremes of climate, taking massive punishment without losing zero or failing.  The Aimpoint CompM4s red dot sight, and its high battery compartment alternative the M4, are the best red dot sights so far produced by Aimpoint®.  They include key improvements, including phenomenal battery life – up to 8 years on a single AA battery!

Adopted by the U.S. Army

The Aimpoint CompM4s has been adopted as the latest version of the U.S. Army’s M68 Close Combat Optic.  This endorsement followed rigorous testing in a variety of extreme environments.  The sight has since started to supplement the previous M68, Aimpoint’s legendary CompM2 with units in combat in Iraq and Afghanistan.

Optional battery compartment height

To suit user preference, the CompM4 series of sights are available in two versions:

  • The CompM4s with a low battery compartment shown on this page.
  • The CompM4 offers a high battery compartment.

The CompM4 and CompM4s are otherwise identical.

Supplied complete and ready to use

The CompM4s sight comes complete with a QRP2 mount and standard AR15 spacer.  Aftermarket quick detachable mounts are available.  A KillFlash® anti-reflection device and MILSPEC flip-up rubber lens covers are also included.


Integral mount

The CompM4s 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 night vision compatability

The CompM4s was designed from the outset to be used with night vision in hunting, law enforcement and military scenarios.

The CompM4s sight will perform excellently with all generations of night vision devices (NVDs), but is ideally suited to 3rd generation technology.

Ultimate image clarity and brightness

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