About this product
The Beretta A300 Ultima 12 Gauge 28in Mossy Oak Bottomland is a synthetic-stock semi-automatic field shotgun designed for waterfowl and upland bird hunting in variable conditions. It updates Beretta's proven gas-operated action with enlarged controls and a recoil-dampening stock system. This model's MobilChoke compatibility and 3-inch chamber make it a versatile platform for different loads and hunting regulations.
What is the Beretta A300 Ultima used for?
The A300 Ultima is used primarily for waterfowl and upland bird hunting over decoys or in brush. Its 28-inch barrel provides a smooth swing for passing shots on ducks and geese, while the Mossy Oak Bottomland camo pattern breaks up the outline in marsh and timber environments. The gas system handles everything from light 2¾-inch target loads to 3-inch magnum waterfowl shells, making it suitable for preseason clay practice and extended days in the blind.
How does the Beretta A300 Ultima compare to the Stevens 555 Sporting O/U 12 Gauge 30in?
The A300 Ultima is a more effective choice for high-volume waterfowl shooting than the Stevens 555 Sporting O/U 12 Gauge. While the Stevens 555 is a reliable, budget-friendly over-under with a classic feel, the Beretta's semi-automatic action provides faster follow-up shots with significantly less perceived recoil, especially with 3-inch magnums. For a hunter firing a box or more of shells in a morning, the A300's gas system and Kick-Off stock reduce fatigue and improve target reacquisition.
What does it weigh and what are the dimensions?
This shotgun is not light, weighing in at approximately 7.1 pounds (3220 grams) unloaded. The overall length with the 28-inch barrel is 48.5 inches, while the length of pull measures 14.5 inches—a standard dimension that fits most adult shooters. The synthetic stock is robust, adding minimal weight but significant durability compared to a traditional walnut stock.
Who is this NOT for?
This shotgun is not for the hunter who prioritizes classic aesthetics or wants the absolute lightest walking gun. The synthetic stock and camo finish lack the refined look of a blued steel and walnut over-under. At over 7 pounds, it's also heavier than some inertia-driven semi-autos or ultralight models purpose-built for mountain grouse or quail hunting, where ounces matter over miles.
What's in the box?
You receive the shotgun with the Kick-Off stock installed, one modified MobilChoke tube, a set of shims for drop and cast adjustment, and a basic security cable lock. Notably, Beretta does not include a full set of choke tubes or a hard case—expect to budget an additional $80-$100 for a full five-choke set and a proper padded soft case for transport.
Is the Beretta A300 Ultima worth it at $999?
At $999, the A300 Ultima is worth the investment for a serious waterfowl or turkey hunter who needs reliable performance in wet, dirty conditions. It bridges the gap between entry-level semi-autos and premium models costing $1,500+, offering Beretta's reputable gas system and build quality. If your hunting consists of a few dozen shells per season, a simpler pump-action or the Stevens 555 Sporting 20 Gauge might be a better value.

Frequently asked questions
- Is it compatible with Benelli choke tubes?
- Yes, it uses the Beretta/Benelli Mobil choke system. All standard MobilChoke tubes, including those sold for Benelli shotguns, will thread directly into the A300 Ultima's barrel. You should pattern your gun with different chokes, but a Modified or Improved Cylinder tube from a Benelli M2 or SBE3 will fit perfectly.
- Does it fit in a standard 50-inch rifle case?
- No, it will not fit unbroken-down in most 50-inch cases. With an overall length of 48.5 inches, you have only 1.5 inches of clearance, which is insufficient for padding. You will need a dedicated shotgun case with an internal length of at least 52 inches, or a takedown case that accommodates the barrel and receiver separately.
- How long does shipping take to an FFL?
- Shipping typically takes 5-7 business days from our warehouse to your designated FFL dealer, provided the FFL's license is on file and current. We ship via FedEx Ground with signature required. Once the dealer receives it, you must complete the 4473 form and pass the NICS check, which adds at least one more business day.
- Can I return it if it doesn't fit?
- No, Ironclad Armory does not accept returns on firearms due to fit, as per federal regulations and our policy. Firearm transfers are final upon completion of the 4473 form. We strongly recommend you handle a similar model at a local dealer to confirm the 14.5-inch length of pull and overall ergonomics before purchasing.
- Does this work with generic 12-gauge slings?
- Yes, it has standard QD sling swivel cups installed in the stock and on the magazine cap. Any 1-inch or 1.25-inch quick-detachable swivels will attach directly. For a simple leather or nylon sling, you'll need Uncle Mike's or Butler Creek swivels, which retail for about $15-30 at most sporting goods stores.
