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.
Magazine dimples or spring retaining devices, if present, need to be smoothed or removed to allow proper function.
Note: Some nuts may 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.
