Benelli

The Benelli M4 2 Round Magazine Extention Tube will attach to the five round magazine Tube and extend your magazine to hold seven 2-3/4" or 3" magnum shells. The Benelli M4 2 round magazine tube utilizes the same spring included in every Benelli M4. A great improvement to magazine capacity and upgrade to the original design of the Benelli M4. The magazine tube is the original black grey cerakote color.
