If you run a Benelli M1, M2, or Super Black Eagle and want more rounds in the magazine tube without replacing the whole gun, this Carlsons extension screws right onto your existing magazine cap. It's built from blued solid steel that matches the shotgun's finish and holds 10 total rounds using standard 2-3/4" shells. The extension ships as a complete kit, so you get everything needed for the install: the tube itself, a spring, a base clamp with swivel stud attachment point, and a high-visibility follower so you can see your round count at a glance.
The design is straightforward. The threaded tube simply replaces your factory magazine cap, which means no permanent modifications to the gun. Installation takes just a few minutes with basic tools, and the included instructions walk you through it. The high-visibility follower helps with both fast loading and knowing when you're getting low on rounds during use.
This extension works well for competition shooting, extended hunting trips where you want fewer reloads, or anyone who wants to maximize their Benelli's capacity. The blued steel construction is durable and stands up to field use, and the spring mechanism feeds rounds reliably without the tight binding that sometimes happens with undersized followers.
Yes, this 10-round extension is designed specifically for Benelli M1, M2, Super Black Eagle I, II, and III models. It threads directly onto your existing magazine cap, so no drilling or permanent modification is needed. Just confirm you have one of those models before ordering.
The extension gives you 10 rounds total capacity when using standard 2-3/4 inch shells, with one additional round in the chamber for a maximum of 11. If you run 3-inch magnum loads, capacity will be slightly lower due to shell length.
No, it's a basic threaded install. The extension replaces your factory magazine cap and screws on by hand with a slight turn using a wrench if needed for snug fitment. Carlsons includes clear instructions, and the whole job takes just a few minutes.
The kit includes the extension tube, a spring, a base clamp with swivel stud attachment point, a high-visibility follower for easy round counting, and installation instructions. You don't need to buy anything else.
At 14.25 inches long, the extension will likely extend a bit beyond a standard 28-inch barrel, depending on how your gun is configured. It won't interfere with shooting or handling, though some people prefer shorter extensions for lighter carry.
The base clamp is designed to accept a quick-detachable swivel, but the swivel itself is not included. You can purchase the quick-detachable hardware separately if you want that option.
