Devices and methods for attaching a shotgun magazine tube

Abstract

A shotgun magazine tube attachment system is disclosed, featuring a threaded magazine tube, a plate, and a threaded nut to secure a shotgun barrel to a receiver. The threaded magazine tube has external threads on both ends for engaging the receiver and the nut, forming a robust mechanical lock without requiring welding or adhesives. The plate, with a circular cutout and upward-projecting tabs, aligns with an undercut shoulder of the barrel to prevent lateral or rotational movement. The threaded nut applies axial force to the plate, securing the barrel and enabling a stable assembly. This system eliminates fixed hangers, allows for barrel and magazine tube interchangeability, and simplifies firearm reconfiguration. The modular design supports various barrel lengths and ammunition capacities, reducing the need for barrel-specific configurations or aftermarket extensions. A method of assembly is provided, enabling users to easily build or reconfigure firearms with standard tools.
