Abstract: Described herein are a shotgun optic plate cover, and methods for making and installing same as well as retrofitting existing shotguns to accommodate the shotgun optic plate cover, with an integrated rear sight to enable either optics enhanced, or non-optics enhanced aiming capabilities for shotguns.

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.

Abstract: Described herein is an integrated feed ramp for a shotgun, methods for making same, and methods of retrofitting existing firearms, wherein the integrated feed ramp feeds shells directly into the loading port of the magazine tube of the shotgun.

Abstract: A firearm system is provided. A pump-action firearm, such as a shotgun, includes a buffer attached to a trigger housing. The buffer consists of a resilient or semi-resilient material and is positioned such as to face towards an opening the receiver in which the magazine tube is partially received. The buffer includes a contoured bottom surface and an upper surface, configured in a way which shortens the space available within an opening of a receiver while accommodating the loading of shells into a magazine tube. Upon moving a shell into the opening, such as by pumping the action, the shell impacts the buffer, which stabilizes the shell prior to being lifted by an elevators. For shorter shells, this reduces the risk of a jamming event. For longer shells, the buffer is configured to compress to accommodate the additional length.
