The hollow, cylindrical portion of a gun through which bullets or shot are discharged. Gun barrels vary in length; the length affects the volume, accuracy, and velocity of the shot, as well as the ease of handling of the firearm itself. Depending on the type of gun, it may be loaded from the front or rear of the barrel.
