Gun sights are devices used to assist in aiming a firearm. They help shooters align their line of sight with the target, improving accuracy. Common types of gun sights include iron sights, which consist of a front post and a rear notch, and optical sights, such as scopes or red dot sights, which provide magnification or a reticle for easier targeting. Properly aligning gun sights is crucial for effective shooting. The shooter must focus on the front sight while keeping the target and rear sight in view. This technique helps ensure that the bullet travels where intended, enhancing overall shooting performance.
