Recoil is the shotgunner’s nemesis. Pound away with even the lightest loads, and eventually marksmanship suffers. What did Beretta do? Its engineers started with a new Micro Core recoil pad made of a soft polymer. Ahead of the pad is the Beretta Kick-Off, a system of hydraulic shock absorbers Beretta claims reduces recoil by as much as 60 percent while also calming muzzle rise. New in the Xtreme is a compressing stock that puts two heavy-duty shock absorbers in the stock itself. Similar in concept to the 1950s Hydro-Coil and externally reminiscent of the Benelli ComforTec stock, the Xtreme’s compressible section is notable as a black chevron running from the top of the comb to the belly of the stock with the peak of the chevron pointing aft. If that isn’t enough, it added a third recoil-attenuating device, common to all A400s, called the Kick-Off 3, which is an oil-dampened buffer that takes the recoil of the bolt.
When any semi-automatic shotgun is fired, the bolt along with its assembly impacts the rear of the receiver, as did the Browning Auto-5’s bolt, with the latter resulting in the characteristic ping for which those guns were famous. Beretta’s oil-dampened buffer absorbs the secondary recoil of the bolt, easing felt recoil and protecting the action.
So if Beretta has a buffer and shock absorbers in the buttstock, what happened to the action return spring? As with the Xtrema 2 and Franchi semi-automatics, Beretta moved it out around the magazine tube, thereby eliminating the old problem of lubricant and dirt accumulation in the butt-housed spring tube that causes so many malfunctions, especially in cold weather.
Although the action retains the sleek appearance of its predecessors, it has been significantly redesigned. The gas piston, located beneath the barrel, is of a new design. Much smaller and shaped like a mushroom in the Unico, Light and Xcel models, it provides more definitive gas metering, and the piston’s circumference has a dual-action seal. The Xtreme’s piston has the more conventional shape, but both styles share the same design of a springy steel band that forms a tight seal but is constructed so that the outer perimeter scrapes the gas cylinder with each stroke, keeping it cleaner. The bolt is welded to the dual action arms so that it remains a unit, and reassembly is quick and slick.
The rotating bolt head is borrowed from Benelli—did I mention Beretta owns both Franchi and Benelli?—and is a proven system used previously on other designs. The lockup is into a hardened barrel extension that is threaded into the barrel. The barrels are made of Steelium, a word coined by Beretta to describe its proprietary alloy of steel, chromium and molybdenum that is used exclusively in the A400 series of shotgun barrels. Beretta’s barrel-making process begins with a billet of Steelium that is deep-drilled, then placed on a mandrel and cold-hammer forged into the nearly completed barrel. Finally the barrels are subjected to a proprietary process called “vacuum extension” that reorients the steel molecules to ultimately provide more consistent patterning and impact.
Beretta had dubbed the A400 action the “Blink,” which implies that it is extremely fast cycling; four shots in one second. From shooting an original A400 Unico throughout the 2008 duck season, and using an Xcel on sporting clays, I can attest to the fact that the action is very fast—and very reliable. There seems to be a race between manufacturers as to who has the fastest cycling action. If you’re shooting exhibitions at numbers of hand-thrown clays, perhaps a very fast action is an advantage, but the truth is that I’ll take reliability any time. The fact is that most of us are better shots when there’s some cool-down time for the brain, so it can focus or re-focus on the duck, dove, clay or whatever is being shot. Reliability is vastly more important. Even the slightest expectation that you will suffer a malfunction is sufficiently distracting to cause a miss. The A400 series of shotguns has provided me with no hint of a malfunction, even when the gun was caked in mud from a 150-yard crawl after some New Jersey black ducks.
The trigger group is built on a polymer base that includes the sculpted safety that is located in front of the trigger. The trigger’s construction is of the common type found on repeaters. At the front is a two-piece carrier that has the bolt latch located at the rear where the carrier and trigger meet. With the hammer cocked, the bolt will not remain locked to the rear unless the small button that activates it is pressed, dropping the carrier. The trigger pull varied over the three guns I’ve extensively shot. None possessed a match-rifle trigger, but all were smooth and not excessively heavy to pull.
New to the Xtreme is the B-Lok magazine cap that is removed and replaced with just a push and a quarter turn. It locks with a cross pin in the cap that snaps into a groove in the magazine tube that holds it in place. The Unico, Light and Xcel have the usual thread-on caps.
Like all other Beretta semi-automatics, the A400s come with a set of shims that allow adjustment of the stock for drop and cast. Adjusting a stock with the Kick-Off is a bit more involved than with a simple buttplate or recoil pad, and it requires some extra tools. The Micro Core pad comes off with a conventional Phillips screwdriver. The Kick-Off device on the Unico, Light and Xcel requires the use of a T15 Torx screwdriver that can be bought at an auto-parts store. While you’re there, buy a 13 mm deep socket to remove the stock bolt (also necessary for Benelli shotguns). Using these tools it is a simple matter to remove the stock and replace the spacer and shim with the set that comes closest to your stock dimensions. Following the instructions in the owner’s manual, and including the extra time to remove the Kick-Off, the process takes about 15 minutes. Curiously, the owner’s manual that accompanied the A400 Xtreme test gun shows a gun called the Novator. When I quizzed Beretta’s Ryan Muety, he said, “The Novator is a model we made specifically for the Russian market,” which cleared up that little mystery.
