If you’re looking for more capacity, this 12 gauge Winchester SXP extension nut is half the equation, allowing installation of a Nordic Components 12ga shotgun extension tube kit on your 12 gauge Winchester SXP shotgun. The nut is required for installation of the tube kit.
Any magazine dimples or spring retaining devices will need to be smoothed or removed to allow proper function.
Note: This 12 gauge Winchester SXP extension nut will also be compatible with other shotguns utilizing the same factory magazine thread pattern, but may require modification/fabrication for proper installation. Visit the shotgun extension fit guide for information on other shotgun models.
