A400 Xtreme Unico Synthetic


A400 Xtreme Unico Synthetic: Super-Versatile Semiauto Shotgun

This black-synthetic semiauto shotgun is today’s most advanced of its kind. It reliably feeds every kind of 12-gauge shell from steel to lead, from 2 ¾” to 3 ½” and from 24 to 64 grams.


It is capable of firing 4 shots in less than one second, and it is extremely soft-recoiling and pleasant to shoot, no matter the type of shell or the length of your hunting or sporting day. Also, it is impeccably balanced and follows your eye naturally to that fast-moving pheasant or clay target, while being quick and easy to field strip and maintain after a long day in the field. Ideal for upland or waterfowl hunting as well as target shooting, the A400 Xtreme Unico Synthetic is the perfect choice for the shotgunner looking for durability as well as versatility.

Low-Profile-ActionFast, Low-Profile Action with Built-In Rails

The A400 action gives you the fastest follow-up shots on the market. Thanks to the unique Blink technology, it shoots 36% quicker than any other type of semiauto shotgun, meaning that while your friend’s action is still cycling, you will already have downed that second bird. While having vault-like strength, it is light and compact, so that the vertical distance between your dominant eye and your supporting hand is kept to a minimum, thereby greatly increasing your chances of hitting the target. Also, the top of the action is equipped with built-in rails, so that you can easily mount the optics of your choice for turkey or deer season, without any gunsmithing.


Low Recoil (70% Recoil Reduction)Low-Recoil

The A400 Xtreme Unico Synthetic gives you several of today’s most advanced recoil reduction concepts right out of the box. Combining hydraulic shock-absorbers with an ultra-soft Micro-Core butt-pad, these systems work together to minimize not only the recoil from the cartridge ignition and firing, but also from the backward-movement of the bolt. Also, the A400 Xtreme Unico is designed to recoil parallel to the cheek mount, which also reduces felt kick while giving you faster follow-up shots. Altogether, these recoil-reduction devices decrease felt recoil by 70%, meaning that you can enjoy a longer day in the field or at the range without your shoulder paying the price.


Durable-FinishDurable Finish, Easy Maintenance

The finish on the OptimaBore HP barrel offers superior resistance to the elements, including water, powder, sand and salt spray. This means that with basic maintenance, this shotgun can easily give you more than a lifetime of hard service. Speaking of maintenance, the A400 Xtreme is easy to field strip, and it disassembles in five easy components that are a snap to clean and to put back together for your next adventure.

1. Adjustable Shim

The adjustable shim system at the buttpad make it easy to customize length of pull, drop and cast to suit your size and shooting style.

2. Anti Corrosion

The barrel features a corrosion-resistant finish that will save you the worry of constant cleanings while in the field.

3. Blink Gas System

When a swarm of birds is flying fast above you, there's no time for hesitation--neither on your part, nor on your shotgun's. Thanks to Blink technology, the A400 action is capable of firing 4 shots in less than one second, making you faster and more successful than any of your hunting buddies.

4. B-Lock

The new fore-end cap offers a safe and fast locking system that makes it easier to assemble and disassemble your shotgun. The cap is closed simply with a 60° rotation and a “click.”

5. Kick Off 3

Laboratory tests have shown two distinct peaks in recoil. The explosion of the ammunition is the first; the impact of the bolt against the receiver is the second. Kick-Off 3 is a third hydraulic damper that cushions this stress on the mechanical components and further reduces recoil by an additional 10% for a total recoil reduction of 70%.

6. Kick Off Mega

The new Kick-Off Mega reduces recoil 60% more than any other shotgun of its kind on the market, and provides comfort because the stock area that makes contact with the face remains stationary. Kick-Off Mega is integral to the design of Beretta's A400 Xtreme and comes standard on all models--together with Kick-Off 3, for a combined 70% recoil reduction.

7. Micro Core Recoil Pad

The Micro Core buttpad is designed to do two primary things. First, to reduce recoil as much as possible, so that even a long session at the range will not tire you and leave you sore. Secondly, and thanks to the type of polymer of which it is constructed, it is engineered to flow smoothly to your shoulder without snagging or catching as many rubber buttpads do.

8. Optima Bore HP

Optima-Bore HP choke geometry was conceived to offer the best ballistic performance available, with steel or lead shot. Thanks to its design, shot pattern remains perfectly uniform whatever the shell size or load, giving you consistency and accuracy on the hunt. Optima-Bore HP choke tubes further enhance the effect.

9. Steelium

Steelium is a proprietary tri-alloy blend that Beretta uses for barrels. Among the many benefits it offers is a combination between lightness and exceptional resistance to shock and deformation. For the hunter, this means absolute shot consistency (steel or lead), accuracy and a shotgun that will give you several lifetimes of enjoyment.

10. Unico

The Unico system is designed to give hunters unprecedented versatility. You can reliably feed any type of 12-gauge shell—lead or steel, mild 2 ¾” to hard-hitting 3 ½” magnums.
