Trijicon is most likely best known for its ACOG red dot point, that is presently issued to the US Marine Corps. Even when you are not a Marine, you must be conscious of the organization's line of traditional Accupoint rifle scopes. They're of extremely large caliber. What makes Trijicon distinctive is its neighboring lighting powered aiming dot system, utilized in conjunction with conventional or mil-dot crosshairs, or with Trijicon's post reticle.
The Trijicon system functions to perfection uses no batteries and allow you to adjust the brightness of the point to where you like it. My experience with the point is that you will seldom need it, if you don't create a custom of hunting in the first and last light. But from time to time, it can make all the difference.
