CARLSON'S
A 12-gauge magazine extension that adds capacity to your Benelli Nova, Super Nova, CZ 712, CZ 912, Beretta Extrema, or Beretta 1301 shotgun. This blued steel tube threads onto your existing magazine cap—no permanent modifications—giving you the extra rounds you need for hunting, competition, or home defense without swapping shotguns or carrying multiple magazines.
Built from solid blued steel, this extension handles the wear of the field and the range. It comes with a spring base clamp fitted with a swivel stud, so you can attach a quick-detachable sling swivel if you want one. The high-visibility follower makes it easy to see where you stand on ammunition, and the threaded design means installation is straightforward—just replace your magazine cap and you're done.
Whether you're running clay courses, chasing waterfowl, or running drills at the range, the extra capacity means fewer reloads and more time on target. The tube works across multiple popular platforms, so if you own more than one of these shotguns, a single extension can rotate between them.

This extension is designed for Benelli Nova and Super Nova, CZ 712 and 912, and Beretta Extrema and 1301 shotguns. If you own one of these models, it will work with your gun.
The extension threads onto your shotgun's magazine cap, replacing it entirely. No gunsmithing or permanent modification is needed. Instructions are included in the box.
You get the blued steel extension tube, a spring base clamp with swivel stud, a high-visibility follower, and installation instructions. Note that a quick-detachable swivel is not included, but the stud on the clamp is threaded to accept one if you want to add it.
This is a 10-round extension, so it increases your magazine capacity to 10 total rounds when installed on your shotgun.
