Beretta A400 Solo KO 12 Gauge — Optifade Marsh

Beretta USA A400 Solo Semi-Auto 12Ga 28in Barrel 3in - KO Optifade Marsh

Disappear into cattails, reeds, and marsh grass with the Beretta A400 Solo KO in Optifade Marsh — a 12 gauge waterfowl semi-auto finished in GORE Optifade's wetland-specific concealment pattern, built for hunters working flooded marshes, moist-soil units, and vegetated wetland edges.

Unlike open-water patterns built to disappear against sky and water, Optifade Marsh uses GORE's biomimicry-based design to break up your silhouette specifically against dense marsh vegetation — cattails, bulrush, and flooded grass — where a generic camo pattern can leave you standing out at exactly the wrong moment. Underneath that concealment, this A400 Solo shares the same core platform as the rest of the lineup: the B-Link Pro gas system for faster, cleaner cycling, a Steelium barrel with an 80mm forcing cone for tight and consistent patterns, and the Kick-Off Plus recoil system to keep you comfortable through long mornings in the blind.

At 7.5 lbs with a 3" chamber, this shotgun cycles everything from standard hunting loads to heavier magnum waterfowl shells without excess punishment on your shoulder. The B-Lok magazine cap removes with a quick 60-degree turn for fast field cleaning after a muddy morning in the marsh, and adjustable stock shims and spacers let you dial in a consistent, repeatable mount for faster, more accurate swings on incoming birds. The aerospace-grade aluminum receiver is drilled and tapped for optics if you want to add a red dot down the line.

Whether you're hunting a flooded timber-adjacent marsh, a moist-soil unit, or dense wetland cover where open-water patterns fall short, the A400 Solo KO Optifade Marsh pairs a concealment pattern built specifically for that environment with Beretta's newest gas and recoil technology.
