Beretta A400 Solo KO 12 Gauge — Realtree Max-7

Beretta USA A400 Solo Semi-Auto 12Ga 28in Barrel 3in - KO Realtree Max-7

Blend into open water and flooded fields with the Beretta A400 Solo KO in Realtree Max-7 — a 12 gauge waterfowl semi-auto finished in one of the most trusted open-water camo patterns on the market, built for hunters working big water, flooded timber edges, and exposed decoy spreads.

Realtree Max-7 was developed specifically for waterfowl and open-terrain hunting, with a pattern designed to break up your outline against sky, water, and sparse cover — a different concealment job than a dense-timber pattern is built for. Underneath that finish, this A400 Solo runs the same proven 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, consistent patterns, and the Kick-Off Plus recoil system to keep you comfortable through a full morning of pass shooting.

At 7.5 lbs with a 3" chamber, this shotgun is built to run everything from standard hunting loads to heavier magnum waterfowl shells without beating you up. The B-Lok magazine cap removes with a quick 60-degree turn for fast field maintenance, and adjustable stock shims and spacers let you fit the gun to your build for a natural, repeatable mount on incoming birds. The aerospace-grade aluminum receiver is drilled and tapped for optics if you want to add a red dot for pass shooting or turkey hunting in the off-season.

Whether you're set up over decoys on big water, working a flooded field edge, or need a dependable semi-auto that matches your open-terrain concealment setup, the A400 Solo KO Realtree Max-7 pairs a purpose-built camo pattern with Beretta's newest gas and recoil technology.
