Holosun laser aiming devices project a visible or infrared beam onto the target, giving a fast reference point for close-quarters aiming or night vision-compatible engagement. They serve military and law enforcement users running night vision devices, along with civilians who want a fast, point-and-shoot aiming reference.

One option carried is the IRIS-GR3, a triple-function device that combines a visible green laser, an infrared aiming laser, and a separate infrared illuminator in one housing, built for use with night vision goggles alongside standard daylight operation.

A visible laser gives a fast aiming reference in daylight or low light without looking through a sight, useful for unconventional shooting positions or close-quarters work. An infrared aiming laser does the same job but is only visible through night vision equipment, so it doesn't give away a shooter's position to the naked eye, while a separate infrared illuminator floods the area with IR light so a night vision device can see clearly when ambient light is too low. Combining all three in one housing lets a shooter switch between daylight and night vision-compatible aiming without swapping devices, and windage and elevation adjustments allow the lasers to be zeroed to the weapon.

Pair a laser with a weapon light for a complete low-light setup, compare against Holosun's thermal sights for passive detection, and see the full range of Holosun optics.
