The now-expired Federal Assault Weapons Ban included a barrel shroud in its list of features for which a semi-automatic pistol could be banned (two features in the list were required).
Shroud of Turin | Beer Barrel Polka | barrel | Crate & Barrel | Cracker Barrel | Barrel | Operation Barrel Roll | North Tonawanda Barrel Organ Factory | Gun barrel | gun barrel | Barrel (storage) | The Wand sits in the Pistol Grip, forming the gun's Gun barrel | Shroud for a Nightingale | Pickle Barrel House | Jesus' shroud | Barrel roll | barrel roll | Barrel of oil equivalent | barrel cactus |
Flash suppressors and barrel shrouds were seen as 'military' features, and were on the list of Federally defined features that could cause a rifle to be defined as illegal, if manufactured after the effective date of the Federal Assault Weapons Ban that went into effect in 1994 in the United States.
Paul Mauser created two different variations of the same rifle, one with a stock strengthened with a barrel shroud and a traditional design following the layout of the 71 series in hope he might be able to overturn the commission's decision, or at least sell his design to the Kingdom of Bavaria, which adopted its own arms.
