A barrel shroud is a covering attached to the barrel of a firearm, that partially or completely encircles the barrel which prevents operators from injuring themselves on a hot barrel. Slides, extensions of the stock 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 in fact do act as such. Barrel shrouds are commonly featured on air-cooled machine guns, where sustained rapid or automatic fire leave the barrel extremely hot and dangerous to the operator. However, shrouds can also be utilized on semi-automatic firearms, 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. 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 protects the user from being burned by a hot barrel and serves as an attachment base for accessories such as sights or sling swivels.

Famous quotes containing the words barrel and/or shroud:
“When I die I want to decompose in a barrel of porter and have it served in all the pubs in Dublin.”
—J.P. (James Patrick)
“It is not however, adulthood itself, but parenthood that forms the glass shroud of memory. For there is an interesting quirk in the memory of women. At 30, women see their adolescence quite clearly. At 30 a woman’s adolescence remains a facet fitting into her current self.... At 40, however, memories of adolescence are blurred. Women of this age look much more to their earlier childhood for memories of themselves and of their mothers. This links up to her typical parenting phase.”
—Terri Apter (20th century)
