The MXT extension nut allows for installation of a Nordic Components MXT 12ga 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 12 gauge shotguns:
- Remington 870
- Remington 1100
- Remington 11-87
- Remington Versa Max
- Remington V3
- Remington Model 11 – Note: Some Model 11 shotguns require the Browning Auto-5 nut.
- Savage 720/745 (requires spacer between barrel lug and nut)
Any magazine dimples or spring retaining devices will need to be smoothed or removed to allow proper function.
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.
