That sight, the Aimpoint CompM4, has been standardized as the Army’s new M68CCO and is now available in the North American market. The US Army has recently awarded Aimpoint with a contract for 163,000 of these sights.
The electronic components in the CompM4 improve upon Aimpoint’s existing state-of-the-art ACET diode circuitry, allowing this new sight to run constantly for over 8 years on a single AA battery. The CompM4 features an internal voltage regulator that allows the sight to operate on any AA size battery available worldwide.
