Benefits of technology

[0006] Briefly described, the present invention generally relates to a modular barrel assembly for firearms such as rifles, shotguns and other long guns, and potentially handguns as well. The barrel assembly generally will include a breech or upstream section that generally mounts to the receiver or frame of the firearm, in communication w

Problems solved by technology

Due to the significant taper or reduction in wall thickness of most typical gun barrels, and in particular shotgun barrels, it is generally not cost effective to machine or cut-down a solid bar or tube having a uniform cross-section to provide the desired taper and reduce the weight of the barrel.
Although more cost effective than machining, such forging operations still typically require significant effort and processing to try to ensure straightness of the bore and concentricity of the bore to the outside surface of the barrel.
More recently, various composite materials also have been used to form firearm barrels, such as for shotguns, but typically have required a metal liner along their inner wall for protection, thus adding to their cost in terms of both materials and manufacturing.

Embodiment Construction

[0013] The present invention relates to a modular barrel assembly 10 (FIG. 1) for a firearm F, which generally will be manufactured in multiple sections or portions using various different materials so as to reduce manufacturing costs, scrap attributed to straightness and concentricity issues for forming the barrel assembly, while also enabling significant weight reduction without adversely affecting performance of the firearm. In one example embodiment, for purposes of illustration, the barrel assembly 10 of the present invention is shown in FIG. 1 as being part of a shotgun F having a receiver 11, including a forward portion at which a chamber 12 of the firearm is defined; a fire control 13 including trigger 14; a stock 16; a magazine tube 17; and a magazine cap 18. It will however, be understood that the principles of the present invention also can be used to form a modular barrel assembly for various other types of firearms, including rifles and other long guns, as well as poten...

Abstract

A modular barrel assembly for firearms that includes a breech section formed from a high-strength material and a barrel section. the barrel section generally is formed separately from the breech section and can be formed from a different, lighter-weight material. Once formed, the barrel and breech sections are attached together to form the complete barrel assembly.
