This Carlsons extension delivers straightforward capacity without complications. Built from blued solid steel, it threads directly onto your existing magazine tube, replacing your factory cap. The kit comes complete with an extended spring, high visibility follower, and barrel clamp with swivel stud, so you're getting everything needed for installation.
The 7-shot extension is designed for Benelli Nova and Super Nova models, as well as CZ 712 and 912 shotguns and Beretta Extrema shotguns. Installation takes just minutes without any gunsmithing or permanent modifications. The threaded design means you simply unscrew your original mag cap and thread this extension on in its place. The included instructions walk you through the process, and the barrel clamp helps stabilize the extension while also providing a sling attachment point.
With 2 3/4-inch shells, this extension brings your total capacity to 7 rounds in the magazine plus 1 in the chamber. Keep in mind that using 3-inch shells reduces the magazine capacity by one round, and 3.5-inch shells reduce it by two. Real-world feedback shows this extension keeps a clean line with the barrel when installed, looking like a factory upgrade rather than an obvious add-on. The blued finish matches standard shotgun aesthetics, and the whole assembly weighs just enough to maintain proper balance without bogging down the gun.
This extension works well for hunters who want more shells in the field without breaking down their gun or carrying extra ammo separately. It's also suitable for sport shooting and general home defense applications. Multiple users report smooth cycling and reliable feeding after installation, though some mention that keeping a fresh snap ring tool on hand makes future disassembly easier if you ever need to service it.
Installation is straightforward – unscrew your factory magazine cap, then thread this extension onto the magazine tube by hand until it seats firmly. The included barrel clamp helps stabilize it on the barrel. Most owners complete installation in under 5 minutes with basic hand tools. Instructions are included in the box.
Yes, but capacity changes. With 2 3/4-inch shells you get 7 rounds total. Using 3-inch shells reduces capacity to 6 rounds, and 3.5-inch shells hold 5 rounds. The extension is designed around 2 3/4-inch ammunition, so that's where you'll get maximum capacity.
While designed for Benelli Nova/Super Nova, CZ 712/912, and Beretta Extrema models, several users report success on semi-auto shotguns with similar magazine tube threading. Compatibility depends on exact magazine tube thread specs, so you may want to verify fit before purchasing for models not on the compatibility list.
No permanent modifications are needed. The extension threads onto your magazine tube and replaces your factory cap, so you can remove it anytime if needed. There's no drilling, soldering, or alterations to the shotgun itself.
