A sight is a device used to line up the muzzle with the shooter’s eye so that he or she can hit the target. Sights are more critical on a firearm that fires a single projectile (rifle and handgun) than on a firearm that shoots a pattern of shot (shotgun). Shotguns usually have a simple pointing bead. Rifles typically have an open, aperture (peep), or telescopic sight. Most handguns have an iron (open) sight, although some specialized handguns have a dot, a laser, or a telescopic sight.
