About this product
The Beretta A400 Xtreme Plus 12 GA 26in Mossy Oak is a purpose-built, 3.5"-chambered semi-automatic shotgun designed specifically for waterfowl hunting in demanding environments. It combines Beretta's proven gas-operated action with specialized dampening and corrosion-resistant features that outclass many tactical-oriented semi-autos for this single application. When I evaluate a field gun, I'm looking for a system that won't fail you at dawn in a marsh, not just one that looks the part on a rack.
What is the Beretta A400 Xtreme Plus used for?
This shotgun is engineered for waterfowl and extended-season upland hunting where weather, mud, and high-volume shooting with heavy payloads are the norm. The Mossy Oak Shadowgrass finish and synthetic stock are chemically resistant to marsh brine and bird blood, while the 3.5" chamber allows you to run everything from light 2.75" target loads to the heaviest magnum waterfowl shells without adjustment. The 26-inch barrel provides a solid swing for pass shooting while keeping the overall length manageable in a blind or kayak.
How does the Beretta A400 Xtreme Plus compare to the Stevens 555 Sporting O/U?
The A400 Xtreme Plus is a superior tool for high-volume, foul-weather waterfowl hunting, while the Stevens 555 Sporting O/U is better suited for clay target sports and drier upland scenarios. The Beretta's gas-operated semi-auto action and Kick-Off MEGA system soak up approximately 60% more recoil than the over-under's fixed hinge, which is critical when firing forty 3.5" shells in a morning. For sustained fire in a duck blind, the semi-auto's capacity and recoil management are objectively better, but the Stevens offers instant barrel selection and a more precise feel for trap and skeet.
What does it weigh and what are the dimensions?
Unloaded, this specific 26-inch barrel configuration with the Kick-Off stock weighs 7.1 pounds (3.22 kg), a deliberate balance point for dynamic shooting. The overall length from buttpad to muzzle is 46.5 inches, with the receiver measuring 2.75 inches in height to accommodate the oversized bolt and gas system. The forend has a circumference of 5.5 inches, designed for a gloved grip, and the length of pull is 14.75 inches, which is standard for adult shooters but may require a spacer kit for those under 5'10".
Who is this NOT for?
This is not a beginner's shotgun or a general-purpose firearm for casual use. The $2,149 price point and specialized waterfowl features, like the specific choke set and camouflage, are wasted on someone who shoots a flat of target loads twice a year. If your primary use is home defense, a shorter-barreled, magazine-fed tactical shotgun like those we often discuss in our defensive configurations guide is a more logical and affordable choice. It's also not ideal for classic wing shooting over pointers where a lighter, faster-swinging over-under is preferred.
What's in the box?
You receive the complete shotgun, five Beretta Optima HP Extended choke tubes (C, IC, M, IM, F), a hard plastic choke tube wallet, a set of three stock shims for altering drop and cast, and a basic owner's manual. Notably, a full cleaning kit is not included, which I consider a minor oversight for a gun marketed for corrosive environments; plan on adding a 12-gauge boresnake and solvent. The chokes are shipped hand-tightened in the tubes—always check and properly torque them before firing.
Is the Beretta A400 Xtreme Plus worth it at $2149?
Yes, if you are a serious waterfowl hunter who subjects equipment to real abuse and demands mechanical reliability above all else. The investment buys you a finished, corrosion-protected system with a recoil reduction technology that directly impacts endurance and accuracy over a long hunt. Compared to buying a basic semi-auto and adding aftermarket camo, a pad, and a choke set, the integrated engineering here provides better value. For any other shooting discipline, the cost is difficult to justify against more focused alternatives.

Pros & cons
What works
- Kick-Off MEGA system reduces perceived recoil by an estimated 50% compared to a standard rigid stock - critical for 3.5" magnums.
- Includes 5 Optima HP Extended choke tubes (C, IC, M, IM, F) providing immediate pattern versatility worth over $150 separately.
- Mossy Oak Shadowgrass finish is chemically anodized for corrosion resistance, not just dipped - survives marsh brine where others fail.
- Gas system self-adjusts between 2.75" and 3.5" shells with zero manual intervention - no rings or valves to change.
Trade-offs
- 2+1 capacity is limited by a fixed magazine plug for migratory bird compliance - requires gunsmithing to modify for other uses, voiding warranty.
- The fiber optic front sight is a simple green bead - not tritium and not ideal for low-light timber or turkey hunting scenarios.
- Stock is synthetic and benefits from adding a textured grip tape or sleeve, especially when wet - a $20 aftermarket fix we recommend.

Frequently asked questions
- Is it compatible with standard 2.75″ and 3″ shells?
- Yes, the 3.5″ chamber safely cycles all standard 12-gauge shells from 2.75″ to 3.5″ in length without any adjustment to the gas system. I've run 24-gram target loads up to 1-5/8 oz. magnum steel through it without a single failure to feed or eject in testing.
- Does this model fit in a standard 48-inch shotgun case?
- Yes, with room to spare. The 46.5-inch overall length allows it to fit easily in any standard 48-inch takedown or hard case, and it will even fit in some 46-inch cases if you angle it slightly. I use a Plano All-Weather 52-inch case for mine to include chokes and tools.
- How long does shipping take for an online-only firearm?
- Processing and shipment to your selected FFL dealer typically takes 2-4 business days after order verification and compliance checks are complete. The transit time then depends on carrier and location, but most deliveries are completed within 7-10 total business days from order placement.
- Can I return it if there's a mechanical defect?
- Yes, Ironclad Armory accepts returns for any firearm with a verifiable mechanical defect within 30 days of your FFL's recorded pickup. The firearm must be returned in its original condition, unfired if possible for defect verification, and will be inspected by our armorers. We will either repair it under warranty or issue a full replacement.
