The sight is mil-spec and projects a visible red dot. The unit is a civilian version of the larger AN-PEQ-2, which is commonly found in the SOPMOD kit and is only available for use by the U.S. Military. The unit comprises a single rugged box that houses a visible red laser, which mounts to a weapon using a Mil-STD-1913 rail. The one major difference between the AN-PEQ-5 and the larger AN-PEQ-2, is the AN-PEQ-5 lacks the IR, or infrared illuminator/target designator which is only visible through night vision or IR imagers. This feature is primarily used by special operations forces to designate targets without giving their position away. Both are products of Insight Technologies.
