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

  • Winchester SX2, SX3, and SX4
  • FN SLP and SLP Mk. 1
  • Browning Gold – Note: Due to issues with excessive magazine spring tension, we do not recommend an extension longer than +4 for this shotgun.
  • Browning Silver

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.
