Iron sights are basic aiming devices used on firearms, consisting of a front sight and a rear sight. They help shooters align their line of sight with the target, allowing for accurate shooting without the need for advanced optics. Iron sights are typically made of metal and are often adjustable for windage and elevation. These sights are commonly found on various types of firearms, including rifles, shotguns, and handguns. While they are simple and durable, they require practice to use effectively, especially in low-light conditions. Many shooters prefer iron sights for their reliability and ease of use in tactical situations.
