Features: The AN/PAQ-4A Infrared Aiming Light is a lightweight, battery powered, pulsating infrared-emitting target marking beam, invisible to the naked eye. It allows the user to accurately engage targets at night while wearing night vision goggles. This aiming light is adapted for use with the M16 rifle, and can be adapted for use on the M60 machine gun, the M2 heavy machine gun, and the M249 SAW.
The AN/PAQ-4A emits a small, pulsing infrared beam, invisible to the naked eye. The system utilizes a Class I laser (Helium-Neon) to generate the aiming point. It marks targets out to a minimum of 100 meters and a maximum of 200-300 meters depending on the ambient light available. The system can be powered by one standard lithium battery, BA-5567, which will operate the aiming light for 40 hours continuously, or two standard AA batteries. The light weighs 9 ounces and is designed to operate in the -54 C (-129 F) to +65 C (149 F) temperature range. It also meets all military specifications for shock and vibration. Once the beam is boresighted to the weapon for "point of aim/point of impact," the firer simply places the pulsating beam on the target and shoots.

Background: The AN/PAQ-4A is in the third year of its production. The PAQ-4A is meant to be used in conjunction with the AN/PVS-7B Night Vision Goggles. The Infrared Aiming Light is intended for employment with all Marine Corps units equipped with night vision goggles. It is versatile and adaptable to a wide variety of missions throughout the Marine Corps. The AN/PAQ-4C is an improved version of the AN/PAQ-4A that will overcome some of the recognized deficiencies in the AN/PAQ-4A.
