Beretta A300 Ultima 12 Gauge 28 in Vent Rib Mossy Oak
About this product
The Beretta A300 Ultima 12 Gauge 28 in Vent Rib Mossy Oak is a semi-automatic field shotgun engineered for upland hunting and clay target shooting with enhanced recoil management and target acquisition features. Built on Beretta's proven gas-operated system, it incorporates practical field upgrades like enlarged controls and weather-resistant synthetic furniture. This configuration balances swing dynamics with durability for sustained use in varied conditions.
What is the Beretta A300 Ultima used for?
This shotgun is optimized for upland bird hunting and clay target disciplines like sporting clays. The 28-inch vent rib barrel provides stable swing characteristics for crossing targets, while the Mossy Oak Shadowgrass finish offers effective concealment in cover. Beretta's Kick-Off system reduces perceived recoil by approximately 30% compared to fixed-stock models, allowing longer shooting sessions without fatigue.
How does the Beretta A300 Ultima compare to the Stevens 555 Sporting O/U?
The A300 Ultima delivers faster follow-up shots with its semi-automatic action versus the Stevens 555's over-under break action. While the Stevens 555 Sporting O/U 12 Gauge offers simpler maintenance and inherent reliability with two barrel choices, the Beretta provides a 3+1 capacity advantage and superior recoil mitigation. For high-volume shooting like waterfowl or tactical training, the semi-auto system proves more efficient.
What does it weigh and what are the dimensions?
This shotgun weighs 7.62 pounds unloaded with an overall length of 47.58 inches. The 28-inch barrel features a 3-inch chamber and accepts Beretta/Benelli Mobil chokes. The balance point sits 14 inches forward of the trigger guard, making it slightly muzzle-heavy compared to field-grade over-unders like the Stevens 555 Sporting 20 Gauge, but this aids in swing-through target tracking.
Who is this NOT for?
This configuration isn't suitable for tactical or home defense roles due to its 28-inch barrel and hunting-specific camouflage. Shooters requiring compact maneuverability should consider a Stevens 555 Sporting Compact with its 26-inch barrels. The semi-automatic action also demands more cleaning than break-action shotguns, making it less ideal for those unwilling to perform regular maintenance.
What's in the box?
The package includes the shotgun, three Mobil choke tubes (Modified, Improved Cylinder, Full), a choke tube wrench, and owner's manual. Beretta ships these with a factory-applied corrosion inhibitor that requires removal before first use. Unlike some competitors, no hard case is included—expect cardboard packaging only.
Is the Beretta A300 Ultima worth it at $999?
At $999, this shotgun offers exceptional value for serious upland hunters and clay shooters. The Kick-Off system alone justifies the price for those shooting over 100 shells per session, while the enlarged controls and reliable gas system outperform Turkish imports in the same price range. Compared to Benelli's Montefeltro at $1,300+, the Beretta provides 90% of the performance at 75% of the cost.

Frequently asked questions
- Is it compatible with Benelli Mobil chokes?
- Yes, it uses the Beretta/Benelli Mobil choke system identical to Benelli's M2 and Montefeltro models. The included Modified, Improved Cylinder, and Full tubes interchange directly with Benelli chokes bearing the Mobil designation.
- Does it fit in a standard 48-inch shotgun case?
- No—the 47.58-inch overall length requires a case with at least 49 inches of interior clearance. I recommend Pelican's 1750 case (50.5" interior) or Savior Equipment's Urban Warfare 52" model for safe transport.
- How long does shipping take to Montana?
- Ironclad Armory processes FFL transfers in 1-2 business days, with shipping via UPS Ground taking 4-6 days to Rocky Mountain states. All shipments require signature confirmation and FFL paperwork completion.
- Can I return it if it doesn't fit?
- Firearms sales are final due to federal regulations, but Ironclad Armory accepts returns for manufacturer defects within 30 days. The shotgun must be unfired and in original packaging, with return shipping at customer's expense.
- Does this work with Carlson's Cremator chokes?
- Yes, Carlson's offers Mobil-compatible Cremator chokes specifically tuned for steel shot. Their Long Range ported choke ($89) patterns tighter than factory Full tubes at 40 yards.
