Definition: In order for a gun to be fired accurately, it must be equipped with some means of sighting it. Very often, this is accomplished by means of a front sight and a rear sight, which are aligned in reference to one another and a target in order to hit said target.
Open sights are the most common form of gun sight, and most often consist of a blade, bead, or post front sight and an open-topped notch as a rear sight. The lack of any type of cover over the sights is what makes them "open" (as opposed to a peep/aperture sight).
One must learn to properly use open sights if you wish to learn how to aim a gun.
