I've got an extra Benelli shotgun magazine extender made by Sure Cycle. This thing is bomb-proof, and includes all of the necessary adapters to extend a Benelli shotgun to be able to hold up to eight shells in the tube. Holds 8 (2 & 3/4 inch shells), 7 (3 inch shells) and 6 (3 & 1/2 inch shells). I've attached this to my SBE II for 2 snow goose hunts in Iowa, and it performed flawlessly. I'm hoping somebody will buy it that will get more use out of it than me (home defense, hunting, etc.) I'd like 70 dollars OBO, these retail for 100. Let me know if you have any questions.
