If you’re looking for more capacity, this 12 gauge Winchester extension nut is half the equation, allowing installation of a Nordic Components 12ga shotgun extension tube kit on your 12 gauge Winchester or Stevens shotgun. The nut is required for installation of the tube kit.
The WIN-120 nut is compatible with the following 12 gauge shotguns:
- Winchester 1200
- Winchester/Ranger 120
- Winchester 1300
- Stevens 320
Any magazine dimples or spring retaining devices will need to be smoothed or removed to allow proper function.
Note: This 12 gauge Winchester 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.
