Sniper scope
A sniper scope or telecopic sight is a kind of telescope that is attached to a rifle. These scopes can help a sniper aim and hit a target far away. Usually, they are made of metal, with glass on each end. They show markings to help aim. A rifle scope works by enlarging target area so you can aim more accurately. Scopes differ from iron sights, which are usually used in crossbows or some machine guns.
