Another product from Lancer Tactical gets reviewed at Fox Airsoft... "The Lancer Tactical Red/Green sight is a pretty standard sight that is equipped with a riser mount for quicker target acquisition and less cheek strain while also increasing the eye relief of the shooter. It can also integrate with iron sights in the event that the batteries go down out in the field.

Unique Features: This particular sight is equipped with a riser to make target acquisition quicker. It sits higher than most sights so it can be used as a stand alone sight or be combined with a number of other sights that make for a much more effective sight.

Suggested uses and applications: This makes for a great sight to use in a number of different ambient lights because of the two color options of the reticle. The human eye is much more receptive to green light than it is to red light so green light is best used during the day while red light is best used in low light so as to not expose the location of the shooter in the dark.

One of the things to keep in mind when using a site like this is Paralax which can cause the dot to 'move around' within the sight."
