A red dot sight is a common classification for a type of non-magnifying reflector (or reflex) sight for firearms, and other devices that require aiming, that gives the user a point of aim in the form of an illuminated red dot. A standard design uses a red light-emitting diode (LED) at the focus of collimating optics which generates a dot-style illuminated reticle that stays in alignment with the weapon the sight is attached to, regardless of eye position (nearly parallax free).

They are considered to be fast-acquisition and easy-to-use gun sights for civilian target shooting, hunting, or in police and military applications. Aside from firearm applications, they are also used on cameras and telescopes. On cameras they are used to photograph flying aircraft, birds in flight, and other distant, quickly moving subjects. Telescopes have a narrow field of view and therefore are often equipped with a secondary “finder scope” such as a red dot sight.

Red dot sights place the target and the reticle on nearly the same optical plane, allowing a single point of focus. This makes them fast-acquisition and easy-to-use sights, allowing the user to keep their attention on the field of view in front of them. They are common in speed shooting sports such as IPSC. Military units and police forces have also adopted them. Red dot sights are also popular among paintball and airsoft players for similar reasons.

Because there is no magnification, the shooter need not worry about parallax or eye relief. The long eye relief makes red dot sights appropriate for firearms with heavy recoil that might drive a conventional short eye relief telescopic sight into the shooter’s eye. Since dot sights can be mounted at any distance from the shooter’s eye with no issues of focus, military rifle mounts usually place the sight in any mechanically-convenient mounting position, such as the carrying handle of the M16 rifle, or on a rail system (typically a Picatinny rail) on top of the rifle. This leaves plenty of room for night vision equipment to be used with the red dot sight.
