Carlsons Magazine Extension 12 Gauge 8-Shot Beretta A400 Xtrema - Blued Steel

The Carlsons Magazine Extension is a direct-replacement tube assembly that lifts the capacity of your Beretta semi-automatic shotgun to 8 rounds of 12 Gauge with 2-3/4" shells. It is engineered specifically for the Beretta A-300 Xtrema, A-400 Xtreme, and TX4 Storm and is not intended for any Unico-pattern variant.

The extension tube is machined from solid steel and finished in a traditional blued coating that matches the factory look of the host shotgun and stands up to weather in the field. The threaded body replaces the factory magazine tube using the included base clamp, and Carlsons ships the kit complete with a matched spring, base clamp, and a high-visibility follower so the extension is ready to install right out of the box.

Built for hunters, waterfowl shooters, and tactical users who want extra rounds on tap without altering the balance of the original shotgun, this 8-shot extension adds meaningful capacity to the Beretta A400 Xtreme platform while keeping the factory-grade ergonomics and handling intact.
