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.
