What Is a Red Dot Sight?

One step up from iron sights, a Red Dot Sight is the simplest optic. They usually don’t have any magnification. The reticle appears as a small dot with no crosshairs and is often called a reflex sight because it’s much faster and more intuitive to the eye than lining up iron sights.

A reflex red dot sight is only effective out to about 100 yards with a rifle or carbine and is limited by the effective range of any handgun it’s mounted to. Some shooters choose to pair their sight with Red Dot Sight Magnifiers to engage targets at a further distance. You’ll often see magnifiers on a Picatinny rail with a QD mount (Quick Disconnect) so that it can be out of the way during closer engagements.

What Is the Purpose of a Red Dot Sight?

Red Dot Sights dramatically increase targeting speed in short-range shooting situations.

What Are the Benefits of Having a Red Dot Sight?

Top-quality red dot scopes are used by the US Military because they are extremely durable, withstand high recoil forces, and have long battery life - in some cases running continuously for 5+ years on a single battery.

Red Dot Sights can be mounted on handguns, shotguns, and rifles, but you will want to make sure the model you are buying is compatible with your firearm's mounting system. For example, many systems use Picatinny rails, but you may need to find a dovetail mount if your firearm doesn’t have a rail setup.
