12 Gauge Benelli Nova/Supernova, Beretta and CZ Extension Nut

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

• Benelli Nova and Supernova
• Beretta 1301 Competition and Tactical
• Beretta 391 Xtrema and Xtrema II
• Beretta A400 Xtreme and Xtreme Plus
• CZ 612, 712, and 912
• Weatherby SA-08
• Fabarm STF 12 - Will fit but a small gap will be left internally between the two magazine tubes.

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.
