Description
The Beretta A400 Xtreme Plus KO 20 Gauge 28in Optifade Marsh is a semi-automatic shotgun built for serious waterfowlers who demand reliability in the blind. Chambered for 3-inch shells, this 20-gauge model weighs just over 6 pounds empty, making it a joy to carry through a long morning hunt. The Optifade Marsh finish blends into cattails and flooded timber, and the Kick-Off MEGA recoil system keeps you on target for fast second shots.

Key Features
- Blink Gas System — Why it matters: cycles faster than traditional inertia systems, so you stay on birds during a flurry of shots. The Blink system also self-cleaning, reducing maintenance in muddy blinds.
- Kick-Off MEGA Recoil Reduction — Why it matters: uses a hydraulic damper and soft comb to cut felt recoil by up to 40%. That means less flinching and a consistent cheek weld, even after a box of 3-inch magnums.
- Optifade Marsh Camouflage — Why it matters: this pattern breaks up your outline in marsh grasses and open water, giving you an edge when ducks are cupped and committed.
- Enlarged Loading Port and Extended Controls — Why it matters: gloved hands work faster with the oversized charging handle and bolt release. The port is beveled for quicker reloads under pressure.
- Steelium Plus Barrel — Why it matters: this barrel uses a deep-drilled, stress-relieved steel that patterns tighter and more consistently than standard chrome-lined tubes. The 28-inch length swings smoothly on crossing shots.
Who It’s For
This shotgun is built for the Southern waterfowler who hunts everything from timber to coastal marshes. It suits the shooter who wants a lighter 20 gauge that still handles 3-inch shells without punishing the shoulder. It’s also a fine choice for a woman or smaller-framed hunter who needs a reliable semi-auto that won’t beat them up.
Pros and Cons
- Pros: Lightweight, soft recoil, fast cycling, excellent camouflage pattern, easy to load with gloved hands.
- Cons: The Kick-Off MEGA system adds a bit of length to the stock, which may not fit shooters with shorter arms. Per Beretta specs, the length of pull is 14.5 inches.

FAQ
Does this shotgun cycle light target loads reliably?
Yes, the Blink gas system is designed to handle a wide range of loads, including 2.75-inch target shells. Per Beretta, it cycles down to 1-ounce loads without issue.
Can I adjust the length of pull on the A400 Xtreme Plus KO?
The stock comes with a fixed length of pull of 14.5 inches due to the Kick-Off MEGA system. You can add aftermarket spacers or a different butt pad, but the hydraulic unit limits adjustment.
What chokes are included with this shotgun?
It ships with five Beretta Optima-Choke HP tubes: C, IC, M, IM, and F. These are steel-shot rated.
Is the Optifade Marsh pattern effective in timber hunting?
It works well in open marshes and flooded timber with dead grass. For dense, dark timber, some hunters prefer Optifade Timber, but Marsh blends fine in most Southern duck holes.
