Beretta A400 Xtreme Plus 12ga/26″ KO- Max-7 – Presleys Outdoors

Description

The Beretta A400 Xtreme Plus 12ga/26″ KO-Max-7, available through Presleys Outdoors at csfirearms.com, is a semiautomatic shotgun built for the serious waterfowl hunter who needs a reliable, fast-cycling platform in challenging conditions. Whether you are working flooded timber in Arkansas, chasing divers on the Chesapeake Bay, or setting decoys in a Saskatchewan slough, this shotgun is designed to deliver consistent performance with heavy payloads and reduce felt recoil to keep you on target for follow-up shots. For the U.S. hunter who values durability, rapid cycling, and reduced fatigue over a long day in the blind, this model offers a practical, field-proven solution.

What This Product Is and Who It’s For

The Beretta A400 Xtreme Plus is a gas-operated, semi-automatic shotgun chambered in 12 gauge with a 3.5-inch chamber, allowing it to fire 2.75-inch, 3-inch, and 3.5-inch shells. This specific configuration features a 26-inch barrel, a blued finish, a green anodized receiver, and a synthetic stock with the KO (Kick-Off) Max-7 recoil reduction system. It is primarily intended for waterfowl and upland bird hunters who require a shotgun that can cycle light target loads and heavy magnum waterfowl loads without adjustment. While its design and features are optimized for hunting, it is also suitable for clay target shooting and recreational range use. It is not designed for concealed carry or home defense, given its barrel length and overall size. Collectors may appreciate the limited-edition green receiver and the Max-7 stock design, but this is a working shotgun built for the field.

Feature Deep-Dive

The Beretta A400 Xtreme Plus is built around the Blink gas operating system, which cycles up to 36% faster than previous Beretta gas systems. This means the action can handle the full range of 12-gauge shells—from light 2.75-inch target loads to heavy 3.5-inch magnum waterfowl loads—without any manual gas port adjustment. For the hunter who switches between shooting doves with lighter loads and geese with heavy steel or bismuth loads, this eliminates the need to fumble with tools or settings in the field. The system also reduces felt recoil by distributing the force over a longer period, which helps keep the muzzle on target for rapid follow-up shots on crossing birds.

The KO Max-7 stock is a key differentiator for this model. It integrates a dual-stage recoil reduction system—one in the buttstock and one in the forend—that works in tandem with the gas system to further dampen recoil. The synthetic stock is also overmolded with a rubberized texture on the grip and forend, providing a secure hold in wet or cold conditions. The stock includes a micro-adjustable shim system that allows the shooter to adjust drop, cast, and length of pull without special tools, making it easier to fit the shotgun to a specific shooter’s build. This is particularly useful for hunters who may be wearing heavy clothing or who share the shotgun with others.

The 26-inch barrel is paired with the Beretta Optima-Bore HP choke system, which is designed to produce consistent, dense patterns with both steel and lead shot. The barrel is also equipped with a steelium Pro barrel, which is cold-hammer-forged from a single piece of steel and features a longer forcing cone that reduces felt recoil and improves pattern quality. The barrel is blued for corrosion resistance, though the green anodized receiver offers additional protection against the elements. The receiver is machined from an aluminum alloy, keeping the overall weight manageable for long walks to the blind.

The A400 Xtreme Plus includes several practical field features. The bolt handle and bolt release are oversized for easier manipulation with gloved hands. The loading port is beveled for faster reloading, and the magazine cap is slotted for use as a tool to tighten the choke tubes. The shotgun also includes a shim kit, a choke tube wrench, and a hard plastic case for storage and transport. The synthetic stock is resistant to water and temperature extremes, making it suitable for use in saltwater marshes or freezing conditions without swelling or cracking.

Beretta’s Kick-Off system in this model is specifically tuned for the heavier loads typically used in waterfowl hunting. The Max-7 designation refers to the seventh generation of the KO system, which uses a hydraulic damper and a spring mechanism to absorb recoil energy. This is not a gimmick—it measurably reduces the peak recoil force transmitted to the shooter’s shoulder, which can make a difference over a full day of shooting 3.5-inch shells. The system is located in both the stock and the forend, which also helps reduce muzzle rise during cycling.

Finally, the green receiver finish is a distinctive aesthetic choice that also serves a practical purpose for waterfowl hunters: it reduces glare and blends better with natural marsh environments than a polished or nickel finish. The blued barrel offers a traditional look while providing adequate corrosion resistance when properly maintained. The combination of the green receiver and black synthetic stock gives the shotgun a modern, subdued appearance that is well-suited for the field.

Ideal Use Cases

This shotgun is primarily designed for waterfowl hunting, including duck, goose, and crane hunting, where the ability to cycle 3.5-inch shells reliably is critical. It is also well-suited for upland bird hunting, such as pheasant or turkey, where a fast-handling 26-inch barrel and reduced recoil offer advantages. The shotgun can be used for clay target shooting, particularly for sporting clays or trap, though the 26-inch barrel may be less ideal for longer-range target presentations. It is not appropriate for concealed carry or home defense due to its size and weight. It is not marketed as a competition shotgun, though it can serve as a reliable backup for recreational shooting.

Compatibility Notes

This shotgun is compatible with all standard 12-gauge ammunition in 2.75-inch, 3-inch, and 3.5-inch shell lengths, including lead, steel, bismuth, and tungsten-based shot. It uses the Beretta Optima-Bore HP choke tube system, which is not interchangeable with standard Beretta Optima-Bore or Mobilchoke tubes. Aftermarket chokes from manufacturers like Carlson’s or Patternmaster are available in the Optima-Bore HP pattern. The synthetic stock is not designed for aftermarket recoil pads, but the KO system is integral and should not be modified. The shotgun accepts standard Beretta A400 magazines and parts, though aftermarket magazine extensions are available but may require modification to the magazine cap. Holsters are not applicable for this model.
