The MXT Coupler allows you to add a second MXT extension tube to your existing extension. Whether you’re concerned about keeping your shotgun at a manageable length in safes and cases without having to completely disassemble your extension, or for those times when a single +9 tube just isn’t quite enough, this coupler maximizes the modularity of your MXT extension assembly.

Oh, and don’t forget to order a new spring to accommodate that increased capacity.

• Allows for combining multiple MXT extension tubes
• Facilitates expanded magazine capacity while retaining modular overall length
• Provides easy removal of additional magazine extension to accommodate use of standard length shotgun cases

NOTE: Be aware that Semi-Auto shotguns within Canada have magazine capacity limits.  Adding a tube to a semi-auto may make it a prohibited device.
