The CompM2 is a battery-powered, non-magnifying red dot type of reflex sight for firearms manufactured by Aimpoint AB.
The sight is designed for use with the M16/M4 family of rifles, but can be mounted on any weapon fitted with an upper Picatinny rail.
The sight is also available on the civilian market and is employed by various law enforcement organizations (especially for SWAT type situations that involve close quarters work) and by recreational shooters.
The sight allows soldiers to engage targets out to 300 meters while keeping both eyes open for situational awareness.
Post combat surveys show an 85 percent acceptance rate of the CCO as an effective optic and for its value for close quarters fighting.
