Rear Sight

A rear sight is a device used on firearms to assist with aiming. It is typically located at the back end of the firearm, near the shooter's eye. The rear sight is designed to align with the front sight and the target, helping the shooter to aim accurately.

There are different types of rear sights, including open sights, aperture sights, and adjustable sights. Open sights consist of a notch or groove at the rear of the firearm, which the shooter aligns with the front sight and the target. Aperture sights, also known as peep sights, have a small hole or aperture through which the shooter looks to align the front sight and the target. Adjustable sights allow the shooter to make adjustments for windage (horizontal alignment) and elevation (vertical alignment) to compensate for different shooting distances.

Rear sights are commonly found on rifles, handguns, and some shotguns. They are an essential component of the firearm's sighting system, helping the shooter to aim accurately and improve their shooting performance.
