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.
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.
