The Tennessee winter marsh is a test of character. When the wind howls across Reelfoot Lake and the greenheads cup their wings into a hard crosswind, you need a shotgun that cycles without hesitation. The Beretta A400 XTR Plus KO in Mossy Oak Bottomland, with its 26-inch barrel and 3.5-inch chamber, is built for that exact moment. Whether you are working the timber along the Mississippi flyway or chasing ruffed grouse in the eastern highlands, this semi-automatic delivers the reliability and handling that Tennessee hunters have come to expect from a Beretta.
What This Product Is and Who It’s For
The Beretta A400 XTR Plus KO is a semi-automatic shotgun chambered in 12-gauge, with a 26-inch barrel and a 3.5-inch chamber. It is designed primarily for waterfowl and upland hunters who need a gas-operated action that can handle heavy magnum loads and light target shells alike without adjustment. This model is part of the XTR Plus line, which means it includes Beretta’s Kick-Off (KO) recoil reduction system, an extended forcing cone, and a Micro-Core recoil pad. The Mossy Oak Bottomland finish provides effective camouflage in Tennessee’s varied terrain, from flooded timber to dry cornfields. While it is not a home defense or concealed carry firearm, it is an excellent choice for hunters, clay target shooters on sporting clays courses, and collectors who appreciate Beretta’s engineering heritage.

Feature Deep-Dive
The Beretta A400 XTR Plus KO is distinguished by its Blink cycling system, which is one of the fastest gas-operated actions on the market. This system uses a self-cleaning piston that reduces fouling buildup, meaning the shotgun cycles reliably even after hundreds of rounds without maintenance. For Tennessee hunters who often spend long days in wet, muddy conditions, this translates to fewer malfunctions when it matters most. The Blink system also allows the action to cycle 2.75-inch target loads as reliably as 3.5-inch magnum waterfowl loads, eliminating the need for a gas valve adjustment. This versatility is a practical advantage for hunters who pattern their guns with different loads before the season opens.
The Kick-Off (KO) recoil reduction system is integrated into the stock and uses hydraulic dampers to absorb up to 40 percent of felt recoil. This is particularly valuable for hunters shooting 3.5-inch shells from a blind or layout boat, where repeated shots can lead to fatigue. The KO system works in concert with the Micro-Core recoil pad, which uses a series of small rubber cells to further dissipate energy. The combination means that a full day of shooting heavy loads leaves you less sore and more focused on your next shot. The stock also includes a shim system that allows you to adjust drop and cast without special tools, so the shotgun can be fitted to your specific build.
The 26-inch barrel is a deliberate choice for hunters who move through cover. It is long enough to provide a smooth swing on crossing shots at ducks over decoys, yet short enough to maneuver in tight upland cover where Tennessee’s thickets and brush demand quick mounting. The barrel features Beretta’s Optima-Bore HP design, which uses a lengthened forcing cone and back-bored barrel to reduce felt recoil and improve pattern uniformity. This means your shot string is more consistent, and you can use tighter chokes without sacrificing pattern density at longer ranges. The red bar front sight with a fiber-optic insert is simple and quick to acquire in low-light conditions, such as early morning duck hunts or late evening dove shoots.
The receiver is machined from aluminum alloy to keep weight down without sacrificing strength. The Mossy Oak Bottomland finish is applied using Beretta’s proprietary process that bonds the camouflage pattern to the metal and synthetic components, ensuring it resists scratching and fading from sun exposure. The synthetic stock is reinforced with a steel insert at the receiver interface to prevent cracking under heavy recoil. The magazine tube is nickel-plated to resist corrosion from moisture and cleaning solvents, a detail that speaks to Beretta’s focus on longevity. The cross-bolt safety is reversible for left-handed shooters, and the bolt release button is oversized for easy operation with gloved hands.
Beretta includes a full set of five Optima-Bore HP chokes (C, IC, M, IM, F) with the XTR Plus KO. These chokes are made from stainless steel and feature a longer parallel section than standard chokes, which improves pattern consistency. The chokes are marked with notches on the rim for easy identification, and they thread into the barrel using a standard Beretta choke wrench. The shotgun also includes a magazine plug for migratory bird hunting, which reduces capacity to two shells in the magazine plus one in the chamber, as required by federal law. The plug is easily removable for non-migratory use.
Ideal Use Cases
This shotgun is purpose-built for hunting. It excels in waterfowl applications, from pass-shooting over decoys to jump-shooting rivers and sloughs. The 3.5-inch chamber allows you to use heavy steel, bismuth, or tungsten loads for geese and large ducks, while the 26-inch barrel keeps the gun balanced for fast follow-up shots. Upland hunters will appreciate the lightweight profile and the ability to cycle light target loads when practicing for the season. The XTR Plus KO is also well-suited for sporting clays and skeet, particularly for shooters who want a gun that mimics the handling of their field gun. It is not recommended for home defense due to its length and open sights, nor for concealed carry, as it is a full-size long gun.
Compatibility Notes
The Beretta A400 XTR Plus KO accepts all 2.75-inch, 3-inch, and 3.5-inch 12-gauge shells, including steel, lead, and non-toxic shot. It is compatible with Beretta’s Optima-Bore HP choke tubes, as well as aftermarket options from manufacturers like Carlson’s and Trulock that are designed for the Optima-Bore HP thread pattern. The gun uses standard Beretta A400 magazines and magazine springs, which are available from Beretta or aftermarket suppliers. For accessories, the receiver is drilled and tapped for a Picatinny rail or scope mount if you prefer a red dot sight, though most hunters use the factory fiber-optic front sight. Holsters are not applicable for this firearm. The stock accepts standard Beretta recoil pads, and replacement shim kits are available for custom fitting.
FAQ Section
1. Can you ship this Beretta A400 XTR Plus KO to my address in Tennessee?
Yes. As a licensed FFL retailer based in Tennessee, we can ship this shotgun to any licensed FFL dealer in Tennessee for pickup. We cannot ship directly to a residential address. If you do not have a preferred FFL dealer, we can recommend one in your area. All shipments comply with state and federal laws, including any local ordinances in your city or county.
2. What is the FFL transfer process for this shotgun?
After you place your order, we will contact you to confirm your chosen FFL dealer’s information. We require the receiving dealer to send us a copy of their current FFL license. Once we receive and verify the license, we ship the firearm to that dealer. The dealer will then contact you to complete the ATF Form 4473 and run a NICS background check. You will pay the dealer’s transfer fee at that time, which is separate from our purchase price.
3. What ammunition types are safe to use in this shotgun?
This shotgun is rated for all SAAMI-spec 12-gauge shells from 2.75 inches to 3.5 inches, including steel shot, lead shot, bismuth, tungsten, and other non-toxic alternatives. We recommend using high-quality factory ammunition from reputable manufacturers. Avoid using reloaded, damaged, or excessively high-pressure loads not intended for gas-operated semi-automatics. The Blink system cycles best with shells producing at least 1,200 fps for consistent function.
