Carbon 12g Magazine Extension Tubes


  • Extremely light weight – 73g for a 500mm (+8rd) tube

  • High strength carbon

  • Impact resistant polymer

  • Includes the MAGLOAD magazine spring

These carbon 12g shotgun magazine extensions are designed to shed weight from the place it affects you the most – the front of the gun. Enjoy faster transitions and easier gun manipulation by lowering the moving mass. Just 73g on a 500mm tube.

Custom cut to length you really can have it your way. Do you want it to finish flush with the end of the gun, or do you want to fit inside the 1320mm box? Cut to your specification, it can be done. Want a +5, +6, +7, +8, +9 tube? Done. Want a +15 tube? Sure, but we really don’t advise it! We can even do a +1 tube if that’s what you need.

High spec carbon wrapped to our specification with an outer weave that has the traditional carbon look you know and love, but with a premium matte finish. Polymer nut and end cap bonded using cutting edge adhesives used in the automotive industry for bonding sports car chassis.

To calculate the number of rounds, count 60mm per round and +60mm for the spring and follower. For example, for a +8rd tube you need 8 x 60mm (480mm) plus 60mm which is 540mm. Cut tolerance is +/- 2mm.

When adding the tube to your cart you will be asked to input the length in mm. For any help or recommendations please don’t hesitate to get in touch using the Contact Us form.

NOTE: 2-3 weeks for delivery, each tube is made to order!
