Running low on ammunition capacity mid-range or mid-competition isn't an option when you're relying on your shotgun. The Carlson's Magazine Tube Extension for Benelli Nova/Super Nova, Beretta Extrema I/II, and CZ 712/912 shotguns adds extra rounds to your magazine tube without requiring a new barrel or major gunsmithing. Finished in parkerized steel—a proven, durable surface treatment that resists corrosion—this extension screws on in place of your factory magazine cap, letting you carry more shells when it counts.
Whether you're running three-gun competitions, training for home defense, or putting rounds downrange at the clay course, capacity matters. This tube comes complete with all the small parts you need: the extension tube itself, internal spring, base clamp, and a high-visibility follower that makes loading and function checks faster and easier. The included instructions walk you through installation step by step.
Because shotgun magazines aren't one-size-fits-all, Carlson's engineered this extension specifically for the Nova, Super Nova, Extrema I, Extrema II, and CZ 712/912 platforms—so fitment is reliable and the extension won't rattle or cause feeding issues. The parkerized finish blends seamlessly with most shotgun finishes and stands up to hard use in the field or on the range.
