S&J Hardware Stoeger M300 Series Magazine Extension

Will fit Stoeger M3K, 3000, 35000, and most Stoeger pump and semi-automatic shotguns.

You will need to select the appropriate type based on where you live, to stay compliant with the law.

Canadian Legal (both sizes are blocked to +2 capacity), and Export Only +2/ +3 (these tubes are unblocked and will allow for +2/+3 capacity). Both versions of the tubes are the same in appearance and installation. The Canadian Legal tube is priced higher because there is more work, time and material involved in producing it. If you order an Export Only +2 or +3 tube to a Canadian address, your order WILL NOT SHIP.

Canadian law mandates that semi-automatic shotgun capacity is restricted to 5 rounds of the largest capable shotshell for that shotgun. The Stoeger 3000 Series of shotguns are designed for 2 3/4" inch shells and 3" shells. So, the legal limit is 5 rounds of 3" shells. Our Canadian Legal magazine extension tube will allow you to load 6 rounds of 2 3/4" shells into your magazine tube, as per Canadian law.
