MXT extension tube nut for Stoeger M2000 and most Franchi autos (see list below). This nut will replace your factory magazine cap and allow installation of an MXT shotgun extension tube.
- Stoeger M2000
- Franchi I-12, Affinity, and Intensity
Note: Some M2000s will not accept the M2000 extension tube nut, due to a change in the magazine threads during production. We unfortunately do not have any information as to a serial number range or other means of identifying these shotguns.
