If you’re looking for more capacity, this 20 gauge shotgun extension nut is half the equation, allowing installation of a Nordic Components 20ga shotgun extension tube kit on your 20 gauge Remington shotgun. The nut is required for installation of the tube kit.
The RM-model nut is compatible with the following 20 gauge shotguns:
- Remington 870
- Remington 1100
- Remington 11-87
Magazine dimples on newer Remington shotguns will need to be smoothed or removed to allow proper function.
This nut will not be compatible with older Remington 1100s using a 12 gauge magazine tube.
Note: This 20 gauge Remington 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.
