This XS Sights Magazine Tube Detent Swage is a purpose-built tool for working on Remington 12 gauge shotgun magazine tube detents. It addresses the detent-style magazine spring and mag cap retention system used on certain Remington models, allowing the follower to pass so a magazine tube extension can be installed. The tool applies controlled swaging to the mag tube detent rather than removing components, simplifying what can otherwise be a difficult modification.
