A400 Xtreme Plus

Description

For waterfowl hunters across the United States who face punishing late-season conditions and heavy steel or bismuth loads, the Beretta A400 Xtreme Plus in 12 gauge with a 26-inch barrel and Optifade Timber finish offers a reliable gas-operated platform designed to cycle a wide range of 2.75-inch to 3.5-inch shells. Whether you are working flooded timber in Arkansas, chasing Canada geese in the Dakotas, or hunting divers on the Great Lakes, this semi-automatic shotgun combines Beretta’s proven Kick-Off recoil reduction system with a corrosion-resistant finish built for wet, muddy environments. It is a field-ready tool for the serious waterfowler who demands consistent performance without excessive maintenance.

What This Product Is and Who It Is For

The Beretta A400 Xtreme Plus is a semi-automatic shotgun chambered in 12 gauge with a 3.5-inch chamber, allowing it to fire everything from light target loads to the heaviest magnum waterfowl shells. This model is specifically designed for waterfowl hunters who need a shotgun that can handle extended days in the field, exposure to moisture and mud, and the recoil of heavy payloads. It is also suitable for upland bird hunters who want a versatile, soft-shooting autoloader, and for shooters who appreciate a gas system that requires less frequent cleaning than some competitors. While it is not intended for home defense or concealed carry due to its size and barrel length, it excels as a dedicated hunting arm for those who prioritize reliability and comfort over long shooting sessions.

Feature Deep-Dive

The A400 Xtreme Plus utilizes Beretta’s fourth-generation gas system, which includes a self-cleaning piston that vents excess gas directly out of the forend. This design reduces the amount of fouling that enters the receiver, meaning the shotgun can run longer between cleanings—a practical advantage during multi-day hunts where time in the field is more valuable than time at a workbench. The system is tuned to cycle reliably with 2.75-inch target loads up to 3.5-inch magnums without manual adjustment, so you can switch from dove loads to steel BBs without changing gas settings.

Recoil management is addressed through the Kick-Off Mega system, which uses a hydraulic damper and a sliding stock mechanism that moves rearward upon firing. This reduces felt recoil by up to 40% compared to standard fixed-stock shotguns, which is noticeable when shooting high-velocity 3.5-inch shells. The Micro-Core butt pad further absorbs vibration, and the comb is designed to keep the shooter’s face in a consistent position for follow-up shots. For hunters who spend all day in a layout blind or a boat, this reduction in cumulative fatigue can translate to better accuracy on later shots.

The Optifade Timber finish is applied to both the receiver and barrel, providing a muted camouflage pattern that blends into wooded wetlands and marsh edges. This is not a painted finish but a durable, matte coating that resists scratching and corrosion from saltwater or mud. The barrel is made from steel treated with Beretta’s internal anti-rust process, and the action components are nickel-plated where exposed to moisture. For hunters who operate in humid conditions or around brackish water, this corrosion resistance extends the service life of the shotgun without requiring constant oiling.

Beretta includes five Mobilchoke HP tubes with this model, covering improved cylinder through full. These chokes are designed for steel shot and are marked with a steel-safe icon, so you can use them with non-toxic ammunition without concern for barrel damage. The extended choke tubes are easy to remove by hand, even with cold or wet fingers, and the wrench included in the box fits securely. Having a full set of chokes from the factory allows you to tailor the pattern for decoying ducks at close range or pass-shooting geese at longer distances.

The 26-inch barrel strikes a balance between swing speed and sight radius, making it maneuverable in tight cover while still providing enough length for smooth tracking on crossing birds. The barrel is back-bored to reduce felt recoil and improve pattern consistency, and the stepped rib with a single red fiber optic front sight offers a clear sight picture in low-light conditions. The receiver is drilled and tapped for mounting optics, should you choose to add a red dot or scope for slug use or turkey hunting.

Ergonomics are addressed through an adjustable length of pull system that uses spacers to change the stock length from 14.25 inches down to 13.25 inches or up to 15.25 inches. The comb height is fixed, but the drop at comb and heel can be adjusted by shimming the stock-to-receiver interface. This allows the shooter to achieve a proper fit for their body type and shooting style, which directly impacts point-of-impact consistency. The synthetic stock is also fitted with sling swivel studs, making it easy to attach a sling for long walks to the blind.

Ideal Use Cases

This shotgun is designed primarily for waterfowl hunting, including ducks, geese, and other migratory birds where 3.5-inch shells are legal and beneficial. It is also well-suited for upland game hunting, such as pheasants or turkeys, particularly when using the included choke tubes to adjust patterns for different bird sizes and ranges. The A400 Xtreme Plus can be used for trap or skeet shooting, though its weight and barrel length are more optimized for field use than competition. It is not intended for home defense or concealed carry due to its size, and it is not the best choice for hunters who primarily shoot light target loads, as the gas system may not cycle very light 2.75-inch shells as reliably as heavier loads.

Compatibility Notes

The A400 Xtreme Plus accepts standard 12-gauge shells with lengths from 2.75 inches to 3.5 inches, including steel, bismuth, tungsten, and lead shot (where legal). It is compatible with all Beretta Mobilchoke HP tubes, as well as aftermarket chokes from brands like Briley and Carlson’s that are designed for the Mobilchoke HP pattern. The shotgun uses a 3+1 magazine capacity with the included plug; removing the plug allows 4+1 capacity in jurisdictions where that is legal. Aftermarket magazine extensions are available from Nordic Components and other manufacturers, though these may require modifications to the forend. Holsters are not applicable to this product; for storage and transport, a soft case or hard case sized for a 26-inch barrel shotgun is recommended. The receiver is drilled and tapped for Beretta-specific optics mounts, and a variety of red dot sights and scopes can be fitted with the appropriate base.

Frequently Asked Questions

Q: Can this shotgun be shipped directly to my home in the United States?
A: No. This firearm must be shipped to a Federal Firearms License (FFL) holder in your state, such as a local gun shop or a licensed dealer. After the transfer, you will complete a background check (Form 4473) and any state-specific requirements before taking possession. We ship only to FFL dealers within the U.S., and we do not ship to P.O. boxes or international addresses.

Q: How does the FFL transfer process work when I order from CSFirerms.com?
A: After placing your order, you will need to provide the contact information of the FFL dealer you wish to receive the shotgun. We will verify the dealer’s license, ship the firearm via a licensed carrier, and provide tracking information. You should contact your chosen FFL in advance to confirm they accept transfers and to understand their fees. The transfer is completed once you pass the background check at the dealer’s location.

Q: What types of ammunition are recommended for this shotgun?
A: The A400 Xtreme Plus is designed to cycle a wide range of 12-gauge ammunition, but it performs most reliably with shells that produce at least 1,200 feet per second velocity. For waterfowl hunting, steel shot loads between 3 and 3.5 inches are standard. Light target loads under 1,150 fps may not cycle the action fully, especially when the gun is new or dirty. We recommend using high-brass or high-velocity loads for the first few boxes to break in the gas system.

Q: What warranty comes with the Beretta A400 Xtreme Plus?
A: This shotgun is covered by Beretta’s standard limited warranty, which covers defects in materials and workmanship for the original owner. The warranty period is typically one year from the date of purchase, though some components (like the barrel and receiver) may have longer coverage. Beretta USA handles warranty claims directly, and we recommend registering your firearm on their website after purchase. This warranty does not cover normal wear, misuse, or modifications.

Q: What is your return policy for firearms?
A: Due to federal regulations and safety considerations, we do not accept returns on firearms for change of mind or fit issues. If the shotgun arrives with a manufacturing defect or is damaged in transit, please contact us within 48 hours of delivery. We will work with Beretta to address warranty claims or arrange for a replacement if the firearm is not in new condition as shipped. Ammunition and accessories are returnable within 30 days if unopened and in original packaging.
