Important Compatibility Information
Confirm the shotgun’s exact model, gauge, magazine-tube dimensions and serial number before ordering. Mossberg has produced several 12-gauge shotgun platforms, and this follower may not fit every model or magazine configuration.
Installation and complete function testing by a qualified gunsmith are recommended. Ensure the shotgun is completely unloaded and check both the chamber and magazine tube before inspection or maintenance.
Compatibility may vary according to the Mossberg model and production year. The product’s material, shade of blue and appearance may differ slightly from the displayed image.
