Advanced Combat Optical GunsightGet totally ready for the action with Trijicon ACOG (Advanced Combat Optical Gunsight) scopes. Crafted for combat and multiple sporting applications, the optical sighting instruments do not make use of batteries for illumination and depend on a different method for the same. Interestingly, they are illuminated by fiber optics that collect natural light on their own or naturally luminescent radioactive particle known as tritium. So the user gets to enjoy an illuminated reticle that can be used for both day and night operation.The Trijicon ACOG riflescopes have a fixed magnification range of 1.5x to 6x and come with varying ballistic reticles on different models.
