Buy Aimpoint® CompM4s | The U.S. Army Standard for Ruggedness

The Aimpoint® CompM4s is the latest evolution of the U.S. Army’s M68CCO (Close Combat Optic), a sight series with over two decades of combat-proven history. Engineered for users who demand professional-quality reliability in extreme environments, the CompM4s is virtually indestructible. The “s” designation signifies the low-mounted battery compartment, which provides a lower profile and protects the adjustment knob from snagging on gear or environment.

When you purchase the Aimpoint® CompM4s Optic from our store, you receive a combat-ready system backed by Free Shipping and Fast 2-5 Day Delivery. Whether for duty use or a premium civilian build, the CompM4s is the pinnacle of the “always-on” red dot philosophy.

Unrivaled Battery Life & AA Compatibility

One of the most significant advantages of the CompM4 series is its power management system.

  • 8-Year Continuous Use: Utilizing Aimpoint’s ACET technology, the CompM4s can run for over 80,000 hours (8 years) on a single, standard AA battery.

  • Universal Power Source: Because it uses a AA battery, you can find replacements in nearly any environment globally—from a convenience store to a remote field post.

  • NVD Optimization: The sight features 16 brightness settings, including 7 night vision compatible modes and 9 daylight settings, ensuring high-contrast dot visibility from high-noon sun to total darkness.

The Geissele Super Precision Upgrade

While the CompM4s is often sold with a standard mount, professional users frequently upgrade to the Geissele Super Precision CompM4 Mount for maximum zero retention.

  1. 1,400 lbs of Clamping Force: Geissele’s updated nut-and-bolt method ensures the optic remains stationary through heavy recoil and severe impacts.

  2. Optimal Height: The Super Precision CompM4 Mount sets the optic at a 1.54″ centerline height, providing a perfect co-witness with standard iron sights.

  3. Shear Lugs: Featuring three integrated shear lugs, the Geissele mount provides superior rigidity compared to factory or “budget” mounting solutions.
