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

• Remington 870
• Remington 1100
• Remington 11-87
• Remington Versa Max
• Remington V3
• Remington Model 11 - Note: Some Model 11 shotguns require the Browning Auto-5 nut.
• Savage 720/745 (requires spacer between barrel lug and nut)

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.
