What is a Red Dot Sight?
A red dot sight is an optic used primarily on firearms for self-defense, tactical applications, and competitive shooting. It uses a red dot as a reticle for aiming at the target and provides a simple aiming mechanism from virtually any shooting position.
All red dot sights work by using a small LED (Light Emitting Diode) to project a red dot onto a specially coated lens, which then reflects the dot to the user’s eye. This enables quick target acquisition and aiming, as the shooter fires the red dot on the target.
In the last couple of years, red dot sights have become popular among firearm enthusiasts due to their ease of use, especially in situations where speedy target acquisition is crucial, like in competitive shooting sports, self-defense, and law enforcement. They are also a game-changer in the shooting field as they favor being used with both eyes open, providing a larger field of view, and better situational awareness.
