Beretta A300 Ultima Patrol 12 Gauge 19.1in Chisel Stock
Pros & cons
What works
- Reliable gas-operated action with a self-compensating piston that reduces fouling by 40% compared to older designs.
- Factory-equipped with critical tactical controls: extended bolt handle and release, oversized safety, and 7-slot Picatinny rail.
- Compact 19.1-inch chrome-lined barrel maintains legal non-NFA status while optimizing handling in corridors and vehicles.
- Robust 7075-T6 aircraft-grade aluminum receiver provides a rigid mounting platform for optics at a total weight of 7.1 lbs.
Trade-offs
- Fixed chisel stock has a 13.5-inch length of pull optimized for armor; shooters without armor may find it slightly short.
- No stock spacers or adjustability included—ergonomics are a committed configuration from the factory.
- Mandatory 250-round high-velocity break-in period adds $100-$150 in ammunition cost before considering the gun 'duty-ready'.

About this product
What is the Beretta A300 Ultima Patrol 12 Gauge 19.1in Chisel Stock? It is a purpose-built, gas-operated semi-automatic tactical shotgun designed for close-quarters defensive applications. The platform emphasizes reliability with a self-regulating piston system and places critical controls within intuitive reach under stress. You're looking at a factory-configured tool, not a project, that balances the rapid handling demands of a patrol gun with the accessory adaptability of a modern fighting shotgun.
What is the Beretta A300 Ultima Patrol used for?
This shotgun is engineered for defensive and tactical employment within confined spaces, where a 19.1-inch barrel provides maximum maneuverability without dropping below the 18-inch minimum for a non-NFA firearm. The direct answer is rapid-response home defense, law enforcement patrol vehicle duty, and structured close-quarters training. The ghost ring sight system prioritizes fast, instinctive target acquisition over precision clay shooting, and the enlarged bolt release functions reliably with gloved hands. Its Mobil Choke system allows for pattern tuning with defensive buckshot loads, which is critical for responsibility in residential environments.
How does the Beretta A300 compare to the Stevens 555 Sporting O/U?
The A300 Ultima Patrol is operationally superior for defensive work, while the Stevens 555 Sporting O/U is a better choice for recreational clay target shooting. The Beretta’s semi-automatic action offers faster follow-up shot potential and reduced perceived recoil compared to a break-action O/U like the Stevens. For defensive roles, the Beretta's 5+1 capacity and Picatinny rail for optics or lights are decisive advantages. Conversely, the Stevens 555 with its 30-inch barrels and traditional walnut stock is optimized for swing and pointability on a skeet or sporting clays field, where the Beretta's compact, aggressive stock geometry would be a distinct hindrance.
What does it weigh and what are the dimensions?
Unloaded, the shotgun weighs 7.1 pounds (113.6 ounces), with an overall length of approximately 39.5 inches from buttpad to muzzle. The critical number for handling is the 19.1-inch chrome-lined barrel, which is the primary factor in the compact profile. The receiver is machined from 7075-T6 aluminum, a grade used in aircraft construction, contributing to durability without excessive weight. The balance point sits just forward of the receiver, making it feel quicker to shoulder than its 7.1-pound spec might suggest, especially when compared to a traditional 28-inch field gun that can weigh the same but feel much muzzle-heavier.
Who is this NOT for?
This is not a suitable primary firearm for a new shooter interested in recreational clays or waterfowl hunting. The compact, defensive-oriented stock has a length of pull optimized for wearing body armor, which can feel short and awkward for a casual shooter in a t-shirt. The ghost ring sight, while fast, is not ideal for breaking distant clay targets or patterning turkey loads at 40 yards. If your primary use case involves shooting 100 rounds of light target load in an afternoon, you’d be better served by a dedicated field model or a competition autoloader with a softer recoil impulse and different ergonomic priorities.
What's in the box?
You receive the complete shotgun, one Modified MobilChoke tube pre-installed, a choke tube wrench, and a standard padlock for the trigger guard per Beretta's packaging protocol. The manual includes specific guidance on the 250-round break-in period using high-velocity ammunition (3 dram equivalent, 1-1/8 oz loads or heavier) to ensure the self-regulating gas system seals properly. Notably, the box does not include any spacers to adjust the length of pull on the fixed chisel stock—what you see is what you get, which reinforces its role-specific design.
Is the Beretta A300 Ultima Patrol worth it at $1499?
At its $1499 price point, it represents a justifiable investment for someone seeking a turn-key, duty-ready tactical shotgun from a proven manufacturer. You are paying for Beretta's legacy of reliable gas-operated shotguns, the robust 7075-T6 receiver, and a factory configuration that would cost significantly more in aftermarket parts to replicate on a standard hunting model. Compared to piecing together a Remington 870 or Mossberg 590 with a shorter barrel, ghost ring sights, and an M-LOK forend, the A300 arrives as a cohesive, tested system. For the shooter who needs a capable defensive tool without the hassle of gunsmithing, the value proposition is clear.

Frequently asked questions
- Is it compatible with standard 12 gauge ammunition?
- Yes, it chambers both 2-3/4" and 3" 12 gauge shells. However, Beretta specifies a 250-round break-in period using high-velocity loads (3 dram equivalent, 1-1/8 oz shot or heavier) to properly seat the gas system. After break-in, it will cycle a wider range of loads, but for defensive reliability, I recommend testing your chosen buckshot or slug extensively.
- Does it fit in a standard shotgun case?
- No, a standard 28" or 30" barrel case will be too long. You will need a compact case designed for shotguns with barrels around 20 inches. The overall length is approximately 39.5 inches, so look for a case with an internal length of 40-42 inches to accommodate it with the choke tube installed.
- How long does shipping take?
- All firearms ship via Ironclad Armory's contract carrier with adult signature required. Processing time is 1-3 business days for compliance verification, and transit time is typically 3-5 business days to the FFL dealer you select at checkout. You will receive tracking information once the shipment is scanned by the carrier.
- Can I mount a red dot sight to this shotgun?
- Yes, the receiver is drilled and tapped and includes a 7-slot Picatinny rail section in the box for mounting. This allows direct attachment of most micro red dots (like the Aimpoint ACRO or Holosun 507C) or a red dot mounted on a Picatinny base. The ghost ring rear sight is removable to maintain a lower optic axis.
- Does this work with all Beretta MobilChokes?
- Yes, it uses the standard Beretta MobilChoke threading system. The included choke is a Modified tube. You can use any aftermarket Beretta MobilChoke, including extended, ported, or tactical varieties from brands like Carlson's or Trulock. The barrel is not compatible with older Beretta Optima or Optima Plus choke systems.
