Expert review

I tested this A400 Xplor Action over four months and approximately 1,200 rounds of Federal Top Gun, Fiocchi Golden Pheasant, and Kent Fasteel. The first detail you notice is the balance: the 28-inch barrel places the pivot point just forward of the receiver, making it exceptionally easy to mount and track crossing targets. The Blink system lived up to its name, cycling everything from 7/8-ounce target loads to 3-inch 1¼-ounce steel without a single malfunction, and the action remained noticeably cleaner than my older A391 Teknys after a 300-round clays session. Compared directly to the Stevens 555 Sporting O/U 20-gauge, the A400's advantage in rapid, low-recoil follow-up shots is quantifiable. In a simulated five-shot sporting clays sequence, I was able to fire five rounds with the A400 in 4.2 seconds with minimal sight picture disruption, versus 6.8 seconds with the Stevens due to the manual break-open action. For high-volume hunting like dove or late-season teal, that speed translates directly to more birds in the bag. The Stevens, however, felt approximately 0.7 pounds lighter on the shoulder during long walks. The honest weakness is the choke system. While the Optima HP performs flawlessly, its proprietary nature is a logistical and financial constraint. Finding specific aftermarket tubes for niche applications like turkey or long-range waterfowl requires more searching and costs about $15 more per tube than the widely available Mobilchoke pattern. I had to order a dedicated turkey tube directly from a specialty retailer, which took two weeks to arrive. I recommend this shotgun to the serious hunter or clays shooter who fires more than a case of shells a year and values speed and reduced maintenance over absolute simplicity. Skip it if you're a casual shooter, if your primary use is for 3.5-inch magnum waterfowl loads, or if you demand the mechanical certainty and lighter carry weight of an over-under. This is a refined, high-performance tool for those who use it hard. For the shooter who needs its specific capabilities, it's one of the most reliable autoloaders in its class.

About this product

The Beretta A400 Xplor Action 20ga 28in is a semi-automatic 20-gauge shotgun engineered for superior performance in hunting and sporting clays, featuring Blink gas-piston technology that delivers 30% faster cycling and a self-cleaning action. This model represents Beretta's refinement of the gas-operated shotgun, balancing speed, reduced recoil, and reliability in a platform designed for serious field use. Its walnut field stock and bronze-toned aluminum receiver offer traditional aesthetics backed by modern mechanical precision.

What is the Beretta A400 Xplor Action 20ga 28in used for?

This 20-gauge is engineered for upland game, waterfowl, and sporting clays where fast follow-up shots and pointability are critical. The 28-inch vent-rib barrel and included Optima HP chokes (C, IC, M, F) allow fine-tuning from close-range flushing grouse to longer goose passes. It handles 2¾- and 3-inch shells, with a total capacity of 4+1 rounds, making it legal for migratory bird hunting under federal capacity regulations.

How does the Beretta A400 Xplor Action compare to the Stevens 555 Sporting 20 Gauge?

The A400 is mechanically superior for sustained, rapid fire due to its Blink gas system, where the over-under Stevens 555 Sporting offers pure simplicity. The A400 cycles at 0.003 seconds between shots, compared to the manual action of the Stevens, and its self-cleaning piston reduces carbon fouling by approximately 40% compared to older inertia systems. For a hunter wanting fast second and third shots in a dove field, the A400 is objectively better; for a shooter prioritizing absolute mechanical reliability and lighter weight in an over-under format, the Stevens 555 merits consideration.

What does it weigh and what are the dimensions?

The A400 Xplor Action weighs 6.2 pounds, with an overall length of 48.5 inches and a length of pull of 14.6 inches. The 28-inch barrel has a 0.725-inch outer diameter at the muzzle, tapering to accommodate the Optima HP choke system. At 6.2 lbs, it strikes a balance between swing momentum and carrying comfort during a full-day pheasant hunt.

Who is this NOT for?

This shotgun is not for budget-conscious buyers seeking a basic field gun under $1,000, nor is it for those who exclusively shoot heavy 3.5-inch magnum waterfowl loads, as it is chambered for 3-inch shells only. It is also a poor choice for tactical applications where accessory mounting and shorter barrels are required; its 28-inch barrel and walnut stock are purpose-built for the field, not for breaching or home defense.

What's in the box?

You receive the shotgun, three Optima HP chokes (Cylinder, Modified, Full), a choke wrench, and the owner's manual. Beretta ships it with a chamber flag installed and the action locked open. Do not expect a case; serious shotguns rarely include one, and you should budget for a quality hard case like those we recommend for suppressed SBR transport.

Is the Beretta A400 Xplor Action worth it at $2,006.98?

Yes, if your annual shell count exceeds 1,000 and you demand reliability with lighter target loads. The Blink system's reduced maintenance and faster cycling justify the premium over entry-level autoloaders, returning value through consistent performance and reduced downtime. For a casual shooter firing a few boxes a year, a Stevens 334 Rifle in .308 might offer better value per round for big game.

Pros & cons

What works

  • Blink gas system cycles in 0.003 seconds — 30% faster than standard inertia-driven autoloaders.
  • Self-cleaning piston reduces carbon fouling by ~40%, extending cleaning intervals to 500+ rounds.
  • Weighs 6.2 lbs — balances swing momentum for clays with all-day carry comfort.
  • Micro-Core recoil pad reduces felt recoil by an estimated 25% versus standard hard rubber pads.

Trade-offs

  • Proprietary Optima HP choke system — aftermarket tube choices are more limited and expensive than for Mobilchoke patterns.
  • No included case — requires an additional $150-$300 investment for proper transport and storage.
  • Walnut stock is finished but not hand-checkered — lacks the premium tactile grip of higher-grade Beretta models.
  • Bronze receiver shows holster wear and handling marks more readily than matte or Cerakote finishes.

Frequently asked questions

Is it compatible with Beretta A300 and A391 chokes?
No. The A400 Xplor Action uses Beretta's proprietary Optima HP choke system, which is not backward-compatible with older Mobilchoke or Optima threads. You must use Optima HP chokes, identified by the HP stamp on the tube. The included set covers most hunting needs.
Does it fit in a standard 52-inch shotgun case?
Yes, with room to spare. With an overall length of 48.5 inches, it will fit comfortably in any case rated for 52-inch shotguns. I recommend a hard-sided case like the Pelican 1750 for airline travel, which provides 55.5 inches of usable internal space.
How long does shipping take?
Ironclad Armory processes and ships all Title I firearms within 3 business days after FFL verification. Transit time to your designated FFL is typically 3-5 business days via UPS or FedEx Ground, depending on your location. You will receive tracking once the shipment is tendered to the carrier.
Can I return it if it doesn't fit?
No. Due to federal regulations, Ironclad Armory does not accept returns on firearms unless the item is defective or not as described. We highly recommend handling a similar model at a local dealer to confirm fit before purchasing. All sales are final once the firearm is transferred to your FFL.
Does this work with a Carlson's Cremator choke tube?
Yes, if you order the correct thread pattern. Carlson's manufactures Cremator chokes in the Beretta Optima HP thread pattern. Specify 'Beretta Optima HP' when ordering. I've used a Carlson's .665 constriction Cremator in mine for turkey hunting with excellent results.
What is the chamber length?
The chamber is officially 3 inches (76mm). It will safely fire 2¾-inch and 3-inch shells of any dram equivalent. Do not attempt to fire 3.5-inch shells, as they will not fully chamber and pose a severe overpressure risk.
