The Aimpoint® CompM4 sight, with high battery compartment, belongs to the CompM4 series sights which are the finest sights Aimpoint has ever produced. Improvements include improved energy efficiency that provides up to 8 years of continuous use from a single AA battery!

The first Aimpoint Comp sight came out in 1995 and today there are more than 1 million sights from the Comp series in use worldwide. All Comp sights are soldier-tested and combat-proven, in other words they are extremely robust high quality products.

The Aimpoint® CompM4 series of sights are the toughest sights that Aimpoint has ever produced and they are the standard infantry soldier sight in many NATO countries. These optics are extremely rugged and operate continuously for up to 8 years using a single AA battery. The competition is not even close. The Aimpoint CompM4s is the latest version of the U.S. Army's M68CCO (Close-Combat Optic), continuing a legacy that Aimpoint has maintained since 1997.

The CompM4 has a top-mounted battery compartment while the CompM4s has a low battery compartment – this is the only difference between the sights.


  • High battery compartment
  • Compatible with every generation of NVD
  • ACET technology allows up to 80,000 hours (over 8 years) of daytime operation on one AA battery
  • Internal voltage regulator allows the CompM4 to be used with any AA size battery
  • 7 NVD settings and 9 daylight settings
  • QRP2 mount has twice the clamping force of the original QRP, and the mounting knob is wider and shorter to improve operation and lower the risk of snagging on other gear
  • Mount base is keyed into to the body of the sight to absorb recoil
  • Mount base screws directly into the sight – no separate sight ring required.
  • 500,000 hours of use on NVD setting
  • 2 MOA dot for close combat and long distance engagement
  • Matches perfectly with Aimpoint® 3XMag
  • Unequaled light transmission
  • Front lens opening is threaded for addition of killFlash® anti-reflective device
  • Submersible to 150 feet (45 meters)
  • Improved adjustment caps are easier to remove and protected against impact
  • Mechanical switch for speed and reliability
