If you're running a Benelli M1, M2, or Super Black Eagle and want more firepower without replacing your entire magazine tube, this Carlsons extension delivers real value. The design threads directly onto your existing magazine cap, replacing it completely and adding significant capacity to your gun's magazine.
What makes it work is straightforward engineering. The extension is machined from blued solid steel, built to handle real field use without corrosion issues. Inside, you get a high-visibility follower that makes it easy to see your rounds and confirm your load status at a glance. The included spring and base clamp handle the mechanics so everything feeds smoothly through your shotgun. Because it replaces just the cap instead of swapping out the whole tube, installation stays simple and doesn't require any permanent modifications to your gun.
The included instructions walk you through the process step by step, and feedback from users shows most people get this done in just a few minutes without any special tools. The base clamp provides stability for the extension if you want to secure it tighter, though many just hand-tighten the threaded connection. The 10.5-inch overall length keeps things balanced and proportional on your gun.
This extension is built specifically for the 8-shot versions of the M1, M2, SBE, and SBEII that use 2.75-inch shells. It gives you a solid boost in magazine capacity without any guesswork about fitment. The blued finish matches the factory appearance, so your gun looks like it came this way from the factory.
This extension is designed for the 8-shot versions of the Benelli M1, M2, SBE, and SBE II that use 2.75-inch shells. If your shotgun is an earlier generation or uses different ammunition, double-check your model number against the compatibility list. Most owners confirm fitment goes smoothly on their target models.
No special tools are required for installation. You just need to remove your magazine cap and thread the extension on by hand. Most users report the job takes only a few minutes and doesn't require any gunsmithing or permanent modifications to your gun.
This extension brings your magazine capacity to 8 rounds total using 2.75-inch shells. The exact increase depends on how many rounds your shotgun originally held, but this gives you a substantial boost for hunting, sport shooting, or practice sessions.
The extension comes complete with the tube itself, a magazine spring, base clamp, high-visibility follower, and printed installation instructions. Everything you need to get up and running is in the box, with no additional purchases required for basic installation.
