SKU: NUT-ST-12-00 Categories: ,


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 ST-model nut is compatible with the following 12 gauge shotguns:

  • Stoeger M2000 (newer versions)
  • Franchi Affinity (all models)
  • Franchi Intensity
  • Franchi 612/I-12

Note: This nut is not compatible with early-production M2000s. If this nut will not fit your M2000, we unfortunately do not have any other nuts that are compatible.

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.
