Abstract
A shell feeding system for a top loading shotgun in one embodiment includes a barrel, receiver, and a magazine. The magazine includes a cavity configured to receive a plurality of ammunition shells in stacked end-to-end relationship. The magazine is positioned above the barrel and extends forward from the receiver. A load gating and locking block engages and guide each shell in a feed pathway towards the lower part of the receiver for chambering. In one embodiment, the receiver and magazine may be formed as a unitary integral structure forming a single piece.

A shotgun, the shotgun comprising:
- a barrel defining a longitudinal axis and an axially extending bore forming a projectile pathway;
- a receiver supporting the barrel;
- an elongated magazine positioned above the barrel and extending axially forward from the receiver,
- the magazine including an axially extending cavity configured to receive a plurality of ammunition shells in stacked end-to-end relationship, the shells each having a head and diametrically enlarged rim;
- a top loading port for loading shells into the magazine;
- a bolt with at least one guide path, wherein the at least one guide path has at least one design;
- and
- a load gate having at least one protrusion, wherein the at least one protrusion moves along the at least one guide path causing the load gate to open and close based on the at least one design in the path, wherein as the bolt moves in a first direction the load gate rises to allow a shell from the magazine to enter the receiver.
