Title
(EN) CONCENTRIC RIFLE BARREL ASSEMBLY
(FR) ENSEMBLE CANON DE FUSIL CONCENTRIQUE
Abstract
(EN)
A concentric rifle barrel assembly includes an outer sleeve having a plurality of threads along the first and second ends, an elongated rifle barrel, and a locking nut. The first end of the rifle barrel is removably positioned within the sleeve and includes a chamber that is sized to receive a firearm cartridge. Threads on the locking nut engage the second end of the sleeve, and a positioning ring that is located a first distance from the first end of the rifle barrel. The first distance being complementary to the length of the sleeve minus the length of the rim of the firearm cartridge for which the barrel is designed to accommodate. Fluting is provided along one or both of the rifle barrel and the sleeve, and the sleeve is designed to receive any number of different rifle barrels each sized to accommodate cartridges of different sizes and calibers.

L'invention concerne un ensemble canon rayé concentrique comprenant un manchon externe doté d'une pluralité de filetages le long des première et seconde extrémités, un canon rayé allongé et un écrou de blocage. La première extrémité du canon rayé est positionnée de manière amovible dans le manchon et comprend une chambre dimensionnée pour recevoir une cartouche d'arme à feu. Des filetages sur l'écrou de blocage mettent en prise la seconde extrémité du manchon, et une bague de positionnement qui est située à une première distance de la première extrémité du canon de fusil. Des filetages de l'écrou de blocage se mettent en prise avec la seconde extrémité du manchon et une bague de positionnement qui est située à une première distance de la première extrémité du canon rayé. Des cannelures sont disposées le long du canon rayé et/ou du manchon, et le manchon est conçu pour recevoir un nombre quelconque de canons de fusil différents, chacun étant dimensionné pour loger des cartouches de tailles et de calibres différents.
