The Carlsons 10-shot extension gives your compatible 12-gauge a genuine firepower boost without any permanent modifications to your gun. The design is straightforward: a blued steel tube with threads that simply replace your existing magazine cap. Installation takes just a few minutes and requires no gunsmithing.
This tube is constructed from solid blued steel built to last through years of field use. The package includes everything necessary for a complete installation: a magazine spring, a base clamp with swivel stud attachment point for quick-detach slings, and a high-visibility follower that makes it easy to see round count at a glance. The clamp secures the tube to your barrel with minimal fuss.
The stated 10-shot capacity applies to standard 2.75-inch shells, which is the most common hunting and sport load. If you run 3-inch magnum rounds, you'll get one fewer round in the tube. For 3.5-inch shells, plan on losing two rounds from the total count. These are physical realities of shotgun design, not product limitations. The extension adds roughly 6 inches to the front of your gun, which pairs well with shorter barrels but may look less proportional on longer hunting setups.
The threading is designed specifically for Nova, Super Nova, CZ 712, CZ 912, Beretta Extrema, and Beretta 1301 models. Double-check your exact gun model before ordering. A few users with CZ models have reported needing to adjust follower positioning to achieve smooth feeding of the final round, though this is more a matter of spring compression tuning than a product defect. Carlsons customer support responds to these situations and can guide you through any tweaks needed.
Installation is quick and straightforward, typically taking less than five minutes. You simply remove your existing factory magazine cap and thread the new extension onto the tube. The included clamp is clamped to the barrel with a basic tool. No permanent modification to your shotgun is needed.
This extension is specifically designed for Benelli Nova, Super Nova, CZ 712, CZ 912, Beretta Extrema, and Beretta 1301 models. If you own a different shotgun, you'll need a different extension. Always confirm your exact model matches the package specifications before ordering.
The stated 10-shot capacity is for 2.75-inch standard shells. With 3-inch magnums, you lose one round of capacity due to physical shell length. Three-and-a-half inch shells will cost you two rounds. This is normal across all shotgun extensions and relates to overall magazine tube dimensions, not product design.
Carlsons extensions are affordable, easy to install, and proven reliable across thousands of users. The solid steel construction holds up well, and the included components eliminate extra shopping. They work particularly well on home defense or sport shotgun setups where the added length doesn't create balance issues.
