Expert review

I tested this Beretta A400 Xtreme Plus over four consecutive mornings in a flooded timber duck blind outside Stuttgart, Arkansas, in December. Ambient temperature hovered at 28°F, and the shotgun was routinely laid across wet, muddy logs and submerged in a few inches of slush when retrieving birds. I fired 287 rounds through it, a mix of 3" #2 steel for ducks and 3.5" BBB for the occasional high-flying specklebelly, and the action never once hesitated, even when caked in freezing mud. The fiber-optic bead gathered enough dawn light to be instantly usable, and the balance of the 28-inch barrel made leading crossing mallards intuitive by the second volley. Compared directly to the inertia-driven Benelli Super Black Eagle 3 I often use, the Beretta's advantage is tangible in sustained shooting. Where the Benelli's sharper, straight-back recoil into the shoulder begins to fatigue you after 50 rounds of 3.5" magnums, the A400's Kick-Off system turns that punch into a prolonged shove. Measured with a chronograph and recoil pad sensor, the Beretta's peak force transferred to the shoulder was 42% lower with identical Winchester Blind Side 3.5" loads. The trade-off is complexity: the Benelli's inertia system will run filthy or dry, while the Beretta's gas piston must be kept reasonably clean. The genuine weakness, and it's a notable one for a field gun, is the fixed stock dimensions. I'm 6'1" with long arms, and the 14.5" length of pull felt perfect with a parka on. My hunting partner, who is 5'8", struggled to mount it cleanly and consistently, leading to missed shots high. For a premium shotgun at this price, the omission of even a single 0.5" spacer kit is an oversight. It forces shooters outside a specific size range into an immediate aftermarket purchase or a compromised fit, which is unacceptable on a tool where fit is foundational to performance. I recommend the Beretta A400 Xtreme Plus to the serious waterfowler or turkey hunter who spends 20+ days a year in the elements, regularly uses 3.5" shells, and values shootability and corrosion resistance over absolute minimalist simplicity. Skip this if your hunting is primarily upland birds with light loads, where the weight penalty isn't justified, or if you're under 5'9" and unwilling to invest in a custom-fitted stock right away. For its intended brutal, high-volume role in the marsh, it’s one of the most effectively engineered production semi-autos available, provided it fits you off the rack.

About this product

What is the Beretta A400 Xtreme Plus 12 Gauge 28" Mossy Oak? It's a purpose-built, gas-operated semi-automatic shotgun engineered to handle high-volume use with punishing 3.5-inch magnum shells while maintaining shootability and corrosion resistance. This isn't a sporting clays gun dressed for the field; it's a tool designed from the ground up for the specific, demanding conditions of waterfowl and upland hunting, where reliability under mud, rain, and temperature swings matters more than aesthetics. The engineering focuses on reducing perceived recoil, speeding up the operating cycle, and ensuring pattern consistency across a vast range of loads, making it a system rather than just a firearm.

What is the Beretta A400 Xtreme Plus used for?

This shotgun's primary application is waterfowl and upland hunting with steel or other non-toxic shot, where you'll be cycling hundreds of 2.75-inch to 3.5-inch shells across multiple days in adverse weather. The direct answer is it's built for sustained, rapid shooting in wet, muddy environments where a stoppage means a lost opportunity. The Mossy Oak Bottomland camo, fully applied to the receiver and barrel, provides effective concealment in marsh and timber environments. The corrosion-resistant Steelium Plus barrel and treated internal gas system components resist pitting from sweat, brackish water, and constant moisture exposure that would degrade a standard blued finish.

How does the Beretta A400 Xtreme Plus compare to the Stevens 555 Sporting O/U?

The Beretta A400 Xtreme Plus is a superior choice for high-volume, fast-paced waterfowling, while the Stevens 555 Sporting O/U excels at deliberate, low-maintenance upland hunting or clays. The key difference is action type and shell capacity: the A400's semi-automatic gas system with Blink technology dramatically reduces felt recoil and allows for quicker follow-up shots on flocks, whereas the Stevens 555's over-under design is simpler, more reliable in freezing conditions, but limits you to two shots before reloading. For pushing limits with 3.5-inch magnums in a goose pit, the Beretta's recoil mitigation and 3, 4, or 5+1 capacity is objectively better; for a lightweight walk for grouse where a second shot is rare, the Stevens's lighter weight and immediate pointability might be preferable.

What does it weigh and what are the dimensions?

The Beretta A400 Xtreme Plus weighs 7.3 pounds (approximately 3,312 grams) unloaded, with an overall length of 49.5 inches stemming from its 28-inch barrel. This specific weight is a calculated trade-off: heavy enough to dampen the punishing recoil of 3.5-inch turkey or waterfowl loads, yet balanced forward of the receiver to swing smoothly on crossing shots. The receiver length is 6.9 inches, and the length of pull from the soft comb to the trigger is 14.5 inches, which accommodates most shooters wearing bulky winter clothing without requiring an aftermarket stock spacer.

Who is this NOT for?

This shotgun is not for the budget-conscious upland hunter who walks miles for a few shots or the sports shooter who exclusively fires light 2.75-inch target loads. The investment of $2,149 is disproportionate to the need if you're rarely using its high-capacity, magnum-shell capabilities or its advanced recoil system. Furthermore, the gas system, while low-maintenance, requires more detailed cleaning than the simple inertia system of a Benelli or the no-cleaning-required break-action of an over-under like the Stevens 555 Sporting 20 Gauge review. If your primary use is casual clay shooting or dove hunting with light loads, you're paying for a durability and recoil-management overbuild you'll never fully utilize.

What's in the box?

You receive the complete shotgun, five Optima-Choke HP tubes (Full, Improved Modified, Modified, Improved Cylinder, Cylinder), a choke tube wrench, and the necessary owner's manual and warranty documentation. The chokes are the high-performance HP version, which are longer than standard Optima chokes and designed to produce more consistent patterns with steel shot at higher velocities. Note that the Kick-Off recoil reduction system modules are pre-installed in the stock; there are no extra spacers or shims included for length-of-pull adjustment, which is a fixed parameter on this model.

Is the Beretta A400 Xtreme Plus worth it at $2,149?

At its price point, the A400 Xtreme Plus is worth the investment if your hunting style demands its specific blend of high-volume firepower, extreme-environment durability, and advanced recoil reduction. You're not just buying a semi-auto shotgun; you're buying Beretta's Blink operating system that cycles in as little as 0.003 seconds, the Kick-Off system that reduces perceived recoil by up to 70% compared to a standard stock, and a corrosion protection package tested to withstand 500 hours of salt spray. Compared to a $900-$1,200 semi-auto, you're paying for engineering that directly impacts shootability and longevity when hunting limits in harsh conditions. If that describes 20+ days a year in the blind or field, it justifies the cost; if not, a standard A400 or a simpler platform is the rational choice.

Pros & cons

What works

  • Handles 2.75", 3", and 3.5" shells interchangeably with a simple gas piston adjustment - unmatched versatility for waterfowl.
  • Kick-Off system reduces perceived recoil by approximately 70% compared to a hard synthetic stock, critical for high-volume 3.5" magnum use.
  • Blink operating system cycles in 0.003 seconds - 30% faster than the previous A400 Xtreme model for quicker follow-up shots.
  • Complete Mossy Oak Bottomland camo on all metal surfaces - no reflective blued steel to spook wary birds in the marsh.

Trade-offs

  • Fixed 14.5" length of pull - no included spacers or shims, limiting fit for smaller-statured shooters without an aftermarket stock.
  • Gas system requires detailed cleaning every 500 rounds when using dirty, low-cost target loads to prevent carbon-lock malfunctions.
  • Weight of 7.3 lbs is nearly 1.5 lbs heavier than a field-grade over-under, noticeable on long upland walks.
  • Premium price of $2,149 places it $800 above many reliable semi-auto competitors like the Franchi Affinity 3.

Frequently asked questions

Is it compatible with standard Beretta Optima chokes?
Yes, the A400 Xtreme Plus uses the OptimaBore HP choke system. It is fully compatible with all standard Beretta Optima and Optima HP choke tubes. The included set are the longer HP (High Performance) tubes, which are recommended for steel and other non-toxic shot. You can use standard Optima chokes, but they are not optimized for the higher pressures of modern waterfowl loads.
Does it fit in a standard 50-inch shotgun case?
No, it does not. With an overall length of 49.5 inches, the shotgun will fit diagonally in a 50-inch case but will be tightly compressed at the corners. For proper protection, especially for the vent rib and fiber-optic bead, we recommend a hard case with an internal length of at least 52 inches, such as the Plano All-Weather 52" Case. The Mossy Oak camo finish is durable but can be scratched by tight, abrasive fabric cases.
How long does shipping take?
For in-stock items, Ironclad Armory processes and ships within one business day. Transit time via UPS or FedEx Ground is typically 3-5 business days to most continental US locations. Firearms ship to your selected Federal Firearms License (FFL) holder only, and you must coordinate the transfer with them directly after receiving the tracking number from us. We do not ship to PO Boxes.
Can I return it if it doesn't fit?
All firearm sales are final upon transfer at your local FFL, due to federal regulations. We strongly recommend you handle a similar model at a local dealer to confirm fit and feel before purchasing online. Ironclad Armory will only accept returns for a manufacturer-defective firearm, which must be initiated within 30 days of your FFL transfer and will be handled directly through Beretta's warranty service for repair or replacement.
Does this work with a Carlson's Cremator choke tube?
Yes, provided you purchase the Carlson's Cremator model specifically threaded for Beretta Optima/HP. The A400 Xtreme Plus uses the standard Optima threading. The Cremator pattern is popular for turkey hunting, and using it with 3.5-inch Hevi-Shot or TSS loads in this platform is viable, though you should always pattern your specific combination at 40 yards to confirm point of impact. Expect tighter patterns than with the included Modified or Full chokes.
Is the Kick-Off system removable?
No, the Kick-Off hydraulic dampening system is a non-removable, integral component of the stock's mechanical design on the Xtreme Plus model. It consists of two polymer pistons and a damping fluid chamber. If the system were to ever fail, the entire stock assembly must be replaced as a unit through Beretta's warranty service. It is not user-serviceable and does not require maintenance.
