8a: a device that aids the eye in aiming or in finding the direction of an object
Glossary of firearms terms (http://www.firearmsmuseum.org.au/Survey/Gloss...
Any of a variety of devices designed to assist in aiming a firearm. For a rifle a normal sight is attained when the top of the front sight and the target are aligned with the centre of the peep or notch of the rear sight. On a revolver the iron sights are generally rudimentary, designed to aid in pointing the weapon rather than in aiming it. Pairs of sights are termed metallic to distinguish them from optical.
A sight is an optical device used to assist aim by guiding the eye. Various forms of sights exist, such as iron sights, red dot sights, and telescopic sights. For aircraft use there are also reflector sights and gyro gunsights.
Sights are used in firearms and in various measurement instruments.
