This extension nut allows for installation of a Nordic Components 20ga shotgun extension tube kit. The nut replaces the factory magazine cap, and is required for installation of the extension 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 nut will also be compatible with other shotguns utilizing the same factory magazine thread pattern, but may require modification/fabrication for proper installation. Nordic Components does not have specific information regarding compatibility beyond the models listed in this description.
