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:
“My long two-pointed ladder’s sticking through a tree
Toward heaven still,
And there’s a barrel that I didn’t fill
Beside it, and there may be two or three
Apples I didn’t pick upon some bough.
But I am done with apple-picking now.”
—Robert Frost (1874–1963)
“Until, on Vinegar Hill, the fatal conclave.
Terraced thousands died, shaking scythes at cannon.
The hillside blushed, soaked in our broken wave.
They buried us without shroud or coffin
And in August the barley grew up out of the grave.”
—Seamus Heaney (b. 1939)
