Beretta A400 Xtreme Plus 12 Gauge, 28″ Barrel, Mossy Oak Shadow Grass

Description

The Beretta A400 Xtreme Plus in 12 Gauge, with a 28-inch barrel and Mossy Oak Bottomland finish, is a semiautomatic shotgun built for the serious waterfowl hunter who demands reliable cycling in the harshest marsh conditions. Whether you are working flooded timber in the Mississippi Flyway or chasing geese over a Dakota field, this left-hand model provides the ergonomics and recoil management needed for long days in the blind. It is a tool designed to perform when wet, muddy, and cold, offering consistent pattern delivery from 2¾-inch field loads to heavy 3½-inch magnums.

What This Product Is and Who It Is For

The Beretta A400 Xtreme Plus is a gas-operated, semiautomatic shotgun intended for waterfowl hunters who spend extended time in unpredictable environments. This specific configuration features a 28-inch barrel, a fixed Kick-Off stock in Mossy Oak Bottomland synthetic, and a left-handed action for southpaw shooters. While it is primarily marketed to duck and goose hunters, its robust construction and recoil-reducing system also make it suitable for turkey hunting or upland bird work where heavy payloads are common. It is not a home defense or concealed carry firearm; it is a dedicated field gun for those who prioritize reliability and comfort over a full day of shooting.

Feature Deep-Dive

The Beretta A400 Xtreme Plus incorporates the Blink gas system, which cycles up to 36% faster than traditional gas-operated shotguns. This is achieved through a redesigned piston and spring assembly that reduces bolt travel time without increasing felt recoil. For waterfowl hunters, this means faster follow-up shots on passing birds, even when using heavy 3½-inch loads. The system is also self-cleaning, using a rotating bolt head and chrome-plated chamber to resist fouling from the waxy residue common in steel shot shells. This reduces the need for field stripping in wet conditions, a practical advantage when you are in a layout blind or a flooded timber stand.

The Kick-Off recoil reduction system is integrated into the stock and uses a hydraulic damper and two sliding counterweights to absorb up to 40% of perceived recoil. This is not a spring-based pad; it is a mechanical system that moves rearward upon firing, spreading the impulse over a longer duration. For a left-handed shooter, this is especially beneficial because the stock geometry already addresses cheek weld and eye alignment, and the Kick-Off further reduces the jarring effect of heavy magnum loads. The system is housed within the synthetic stock, which is reinforced with a fiberglass structure to prevent cracking under repeated use in cold temperatures.

The 28-inch barrel features Beretta’s Steelium Optima-Bore HP technology, which uses a deep-drilling process to create a gradual taper from the chamber to the muzzle. This reduces shot deformation and produces denser patterns, particularly with steel shot at extended ranges. The bore is also honed and polished to a mirror finish, which minimizes friction and leading. The barrel comes with a set of five interchangeable Optima-Bore HP choke tubes (C, IC, M, IM, F), each with a knurled end for tool-less removal. The extended forcing cone is 4 inches long, which allows shot to transition into the bore more gradually, reducing pattern fliers.

The synthetic stock is finished in Mossy Oak Bottomland, a pattern designed for flooded timber and marsh environments where browns, tans, and dark greens dominate. The stock includes a shim system that allows adjustment of drop at comb, cast, and length of pull, enabling the shooter to fine-tune fit without removing the stock. The pistol grip is textured with a rubber-like insert for secure handling in wet gloves, and the forend is similarly textured with a slight palm swell. The left-hand configuration includes a reversed safety, a left-facing ejection port, and a bolt release lever accessible to the left thumb, making operation natural for southpaw shooters.

The receiver is made from anodized aluminum alloy, which keeps weight down without sacrificing strength. It is drilled and tapped for mounting optics such as a red dot or a ghost ring sight, which can be useful for turkey hunting or slug use. The trigger guard is oversized to accommodate gloved fingers, and the magazine cut-off switch allows the shooter to quickly unload the chamber without cycling shells through the action—useful when crossing fences or entering a boat. The magazine plug is easily removable for non-migratory bird hunting, increasing capacity to 4+1 rounds.

Ideal Use Cases

• Waterfowl Hunting: The primary use case. The 3.5-inch chamber handles steel, bismuth, and tungsten loads for ducks and geese. The Mossy Oak Bottomland pattern blends into flooded timber, marsh grass, and cattails.
• Turkey Hunting: With the barrel’s ability to pattern heavy 3-inch turkey loads and the receiver’s optics-ready capability, this shotgun is a solid choice for spring gobbler season.
• Upland Bird Hunting: The 28-inch barrel swings well for pheasants and grouse, and the Kick-Off system reduces fatigue when carrying the gun over long distances.
• Clay Shooting: While not a dedicated target gun, the A400 Xtreme Plus can be used for trap or skeet practice, particularly when using 2¾-inch target loads. The fast cycling Blink system helps with doubles.

Compatibility Notes

• Ammunition: This shotgun cycles 2¾-inch, 3-inch, and 3½-inch shells reliably. It is designed for lead, steel, bismuth, and tungsten shot. Avoid using reloaded or low-pressure target loads below 1200 fps, as the gas system may not cycle them consistently. For best results, use factory ammunition rated for semiautomatic shotguns.
• Choke Tubes: Uses Beretta Optima-Bore HP chokes (Mobilchoke pattern). Aftermarket options from Briley, Carlson’s, and Kicks are available. Do not use older Optima-Bore chokes without the HP designation, as they have different threading.
• Accessories: The receiver is drilled and tapped for Beretta-style scope bases (e.g., Beretta 400 series mount). Magazine extensions are available from Nordic Components and Briley, but must be paired with a longer magazine spring. Sling swivel studs are pre-installed on the forend and stock.
• Holsters/Slings: Not applicable for this firearm. Use a padded sling for field carry (e.g., Butler Creek or Allen). No holster compatibility exists for shotguns.
• Cleaning: Use standard shotgun cleaning kits with a 12-gauge bore brush and jag. The self-cleaning piston reduces fouling, but periodic disassembly of the gas system is recommended every 500 rounds.

FAQ Section

1. Can this shotgun be shipped directly to my home address in the United States?
No. Federal law requires that all firearms purchased from a licensed FFL dealer (like C.S. Firearms) be shipped to another FFL dealer in your state for transfer. We will ship to a dealer of your choice, or we can recommend one near your zip code. You must arrange the transfer with the receiving FFL before we ship.

2. How does the FFL transfer process work for this Beretta A400 Xtreme Plus?
After you place your order, you will receive an email asking for your chosen FFL dealer’s contact information. We will verify their license and ship the shotgun to them. You then visit the dealer, complete a Form 4473, and pass a NICS background check. Transfer fees vary by dealer and are not included in the purchase price. Expect 3-7 business days for shipping and processing.

3. Can I use 2¾-inch target loads in this 3.5-inch chamber without issues?
Yes, but only if the shells are rated for semiautomatic operation (minimum 1200 fps). Light target loads (e.g., 1145 fps) may not generate enough gas pressure to cycle the action reliably, resulting in failure to eject or feed. For consistent performance, use 1⅛-ounce loads at 1200 fps or higher. The chamber is designed to handle shorter shells without problems.

4. What warranty does Beretta offer on this shotgun, and how do I claim it?
Beretta provides a limited lifetime warranty to the original owner for defects in materials and workmanship. This does not cover normal wear, misuse, or modifications. To claim warranty service, contact Beretta USA customer service (1-800-636-3420) with your serial number and proof of purchase. You may be required to ship the firearm to an authorized service center at your expense for evaluation.

5. What is your return policy for firearms?
All firearm sales are final due to federal regulations. If the shotgun arrives damaged or with a manufacturer defect, we will assist you in filing a warranty claim with Beretta. We do not accept returns for cosmetic issues, change of mind, or fitment problems. Please inspect the firearm at your FFL dealer upon transfer before accepting it.
