context_page_description: A barrel shroud is an external covering that envelops the barrel of a firearm, to prevent unwanted direct contact with the barrel. Moving coverings such as pistol slides, fore-end extension of the gunstock/chassis that do not fully encircle the barrel, and the receiver of a firearm itself are generally not described as barrel shrouds, though they can functionally act as such. A handguard is a type of barrel shrouding that is designed specifically for the operator to grip more frontally on the gun for better stability and control.
  Full-length barrel shrouds are commonly featured on air-cooled machine guns, where frequent rapid bursts or sustained automatic fire will leave the barrel extremely hot and dangerous to the operator. However, shrouds can also be utilized on semi-automatic firearms, especially the ones with light-weight barrels, as even a small number of shots can heat up a barrel enough to injure an operator in certain circumstances.
  Barrel shrouds are also used on pump-action shotguns. The military trench shotgun features a ventilated metal handguard with a bayonet attachment lug.
context_section_description: A barrel shroud is an external covering that envelops (either partially or full-length) the barrel of a firearm, to prevent unwanted direct contact with the barrel (e.g. the operator accidentally touching a hot barrel, which can lead to burns).  Moving coverings such as pistol slides, fore-end extension of the gunstock/chassis that do not fully encircle the barrel, and the receiver (or frame) of a firearm itself are generally not described as barrel shrouds, though they can functionally act as such.  A handguard is a type of (often only half-length) barrel shrouding that is designed specifically for the operator to grip more frontally on the gun for better stability and control.

  Barrel shrouds are also used on pump-action shotguns.  The military trench shotgun features a ventilated metal handguard with a bayonet attachment lug. Ventilated handguards or heat shields (usually without bayonet lugs) are also used on police riot shotguns and shotguns marketed for civilian self-defense. The heat shield also serves as an attachment base for accessories such as sights or sling swivels.
