A ventilated (vent) rib is a flat plane that is raised above the barrel of a firearm — most commonly on shotguns. There are gaps between the barrel and the rib, which is supported over the barrel by a series of fastenings to provide better cooling and to eliminate glare on the barrel for the shooter as well as offer a straight sighting plane. Some handguns also have ventilated or solid ribs.
