PARALLAX-FREE

Aimpoint sights are parallax-free, which means that the visible dot remains parallel to the bore of your weapon no matter what angle your eye is in relation to the sight.
This means you never have to worry about centering the dot inside the sight. When the dot is on target, so are you.
You will be able to get on target fast and can forget about being challenged by bad light or moving targets.

The conventional lens used in the majority of other red dot sights gives an angled reflection when the dot is not centered on the lens. The farther the dot from the center of the lens, the greater the deviation from the optical axis. In this case, the point of aim and the point of impact can never be the same.
