Description:

Enhance your shotgun's capacity with the MXT Extension Tube Kits!

The Nordic Components MXT Extension Tube Kits offer a universal fit solution for extending the capacity of various 12ga shotguns. These kits are designed to provide an easy way to increase your shotgun's magazine capacity, ensuring you have the performance you need when it counts.

Product Features:

  • Includes the extension tube in the capacity you select.
  • Comes with the correct length spring for the tube.
  • Includes an end cap for secure installation.
  • Compatible with "B" Models engineered for flush fit on Benelli M1/M2 (+3B on 18.5" barrel; +5B on 21" barrel).
  • Constructed from anodized 6061 aluminum, providing strength while minimizing weight.
  • Features a relief groove to eliminate barrel clamp travel, ensuring repeatable placement after disassembly (+2 through +9 extensions only).
  • Relief groove is off-center for location adjustment by reversing the tube.
  • Machined with matching thread pitch on both ends for easy tube reversal.

To complete your setup, be sure to select the correct Nordic Components Shotgun Extension Tube Nut that fits your shotgun, available for purchase separately.

  3. The tubes are made of anodized 6061 aluminum with a relief groove to prevent barrel clamp travel and allow for repeatable placement.
