Carlsons Magazine Extension 12 Gauge 8-Shot 8.25" Benelli Nova/Super Nova - Beretta Extrema/1301 - CZ 712/912

The Carlsons Magazine Extension adds capacity to your 12 gauge shotgun, bringing the magazine tube out to an 8-shot configuration. Constructed from blued solid steel, this extension is a straightforward upgrade for shooters looking to add rounds on tap.

Designed to fit the Benelli Nova and Super Nova, the Beretta Extrema and 1301, and the CZ 712 and 912 shotguns, the extension measures 8.25" overall and installs in place of the factory magazine tube. The kit ships complete with the steel extension tube, a replacement magazine spring, a base clamp (some versions include an integrated swivel stud for quick-detach sling attachment), and a high-visibility follower for reliable feeding.

Whether you run your shotgun hard at the range or use it for hunting, this Carlsons extension delivers the extra capacity in a clean, blued-steel package.
