Description
Beretta has been building some of the most reliable gas-operated semi-auto shotguns in the world for generations, and the A400 Xtreme Plus represents the top of that mountain. Chambered in 12 gauge with a 3.5" chamber and a 26" Steelium Plus barrel wrapped in Gore Optifade Marsh camo, this gun was engineered specifically for waterfowlers who need their shotgun to work every single time, no matter how cold, wet, or miserable opening morning gets. The Aqua Tech Shield surface treatment covers the gun inside and out, protecting metal components from corrosion caused by water, powder residue, salt spray, and sand.
What Makes the A400 Xtreme Plus Different in the Duck Blind
The Blink gas operating system is at the heart of what makes this shotgun stand out. It uses a rotating bolt head and a self-cleaning exhaust valve that vents excess gas pressure, which allows the gun to cycle reliably across a massive range of loads, from light 7/8 oz. target shells all the way up to 2.25 oz. 3.5" steel and bismuth magnums, without any manual adjustment. Beretta claims the Blink system cycles 36 percent faster than other semi-auto platforms, which translates to fast, decisive follow-up shots when birds are working through your spread. Beyond raw cycling speed, the Blink system's self-cleaning piston design also means the gun runs cleaner and longer between maintenance sessions, which matters when you're grinding out a multi-day hunt.
The Kick-Off Mega Recoil System on the Xtreme Plus
Felt recoil is where the A400 Xtreme Plus separates itself from the competition in a real, tangible way. The Kick-Off Mega system uses hydraulic shock absorbers built into the synthetic stock to address two distinct recoil peaks: the initial firing impulse and the secondary impact of the bolt slamming back into the receiver. Together with a soft comb insert that reduces cheek slap and a Micro-Core recoil pad, the combined system is rated to reduce felt recoil by up to 70 percent. For anyone who regularly shoots heavy non-toxic loads, that number is hard to ignore. The gun also ships with a 26" step-rib Steelium Plus barrel featuring a fiber optic front sight and a steel mid-bead, lengthened forcing cones for improved pattern consistency, and a set of five extended Optima-Choke HP chokes covering the full spread from Cylinder to Full. The enlarged loading port, extended charging handle, and oversized bolt release are all factory-standard features designed for gloved hands in miserable weather. The receiver is drilled and tapped for a Picatinny rail if you want to throw a red dot on it for turkey season.

Frequently Asked Questions
What load range will the Beretta A400 Xtreme Plus cycle reliably?
The Blink gas operating system is designed to handle an exceptionally wide range of ammunition without any manual adjustment. It will reliably cycle everything from light 7/8 oz. 2.75" target loads up to heavy 2.25 oz. 3.5" magnum waterfowl and turkey loads. The self-cleaning exhaust valve vents excess gas pressure automatically, which is what gives it this flexibility across such a broad load spectrum.
How does the Kick-Off Mega system actually reduce recoil?
The system works in two stages. Kick-Off Mega uses spring-loaded hydraulic shock absorbers built into the stock that compress during the initial firing impulse, and a third hydraulic dampener just behind the receiver addresses the secondary recoil peak caused by the bolt slamming rearward at the end of its travel. Add in the soft comb cheek pad and Micro-Core recoil pad, and Beretta rates the combined system at up to 70 percent felt recoil reduction. In real-world shooting, the difference with heavy steel or bismuth loads is very noticeable.
Is the A400 Xtreme Plus a good choice for anything beyond waterfowl?
It was built for the duck blind first, but it's a genuinely versatile gun. The Blink system cycles light target loads as smoothly as heavy magnums, making it a solid option for dove, sporting clays practice, and summer skeet leagues. The receiver is also drilled and tapped for a Picatinny rail, so adding a red dot for turkey season is straightforward. It's on the heavier side for upland work, but for any application where you're shooting volume or heavy loads, the weight and recoil system work in your favor.
Why does this model show a 2+1 capacity when the magazine tube holds more shells?
The A400 Xtreme Plus ships with a magazine plug installed, limiting capacity to 2+1 as required for migratory bird hunting under federal regulations. The tubular magazine itself has a larger capacity, and the plug can be removed when used in applications where capacity restrictions do not apply.
Does the Gore Optifade Marsh finish hold up in saltwater and harsh environments?
Beretta applies their Aqua Tech Shield surface treatment across the gun, which provides corrosion and wear protection both inside and outside the action. The finish is specifically designed to resist water, salt spray, powder residue, and sand. The Optifade camo pattern is applied over this treatment, so you're not giving up durability for the camouflage.
Can the stock fit be adjusted on the A400 Xtreme Plus?
Yes. The gun ships with a length of pull of approximately 14.5" out of the box and includes spacers that allow you to extend it up to 15" or so. The stock also features an adjustable shim system that lets you dial in the drop at comb and cast for a more personalized fit. Beretta recommends having any significant stock adjustments done by a qualified gunsmith.
