  • Beretta A391 xtremaA2

    NEW BERETTA A391 XTREMA2
    Designed for the use of Super Magnum 12 ga. 3 ½ in. (89 mm) cartridges, but capable of functioning with lighter cartridges, the new Beretta A391 Xtrema2 gas operated semiautomatic is the ideal shotgun for long distance shooting and the most difficult game.

    MODERN DESIGN, ULTIMATE TECHNOLOGY
    Streamlined Shapes. The skilfully rounded receiver blends perfectly with the stock grip and it permits instinctive, rapid target acquisition. Impeccable balance makes this shotgun easy- and fast to handle. The strongly outlined sides of the receiver confer a distintinctive character to the gun.
    The slim fore-end and the stock boast a new ergonomic design that facilitates the ount of the shotgun. The accurate design of the trigger guard elegantly merges with the receiver.
    The enlarged opening of the trigger guard allows the use of gloves. The top of the receiver is designed to accept (with an optional Weaver base) optics and other aiming systems.

    Stock And Fore-End In Technopolymer.

    The stock and fore-end are produced in durable, resistant, fiberglass reinforced technopolymer that ensures anti-scratch properties and an improved feel in cold weather.Special extended soft plastic inserts are overmolded on the gripping areas of the stock and fore-end to guarantee a secure grip also in adverse weather conditions and to absorb vibrations when shooting.

    EXCLUSIVE AQUA TEK PROTECTION
    Aqua Technology is the name given to the exclusive special surface and protective treatments that are applied to the metal parts of the new Beretta A391 Xtrema2 shotgun.
    The steel barrel is chrome-plated inside to withstand the rigors of steel shot. The external surface of the barrel is first blued and then covered that an exclusive protective coating which remarkably increases its resistance to corrosion. The receiver is made of black anodized aluminum alloy and also boasts the same protective coating. All the internal parts are either nickel or chrome plated, or they are protected by a special process based on a ionic deposition which impregnates the surfaces with ceramic compounds and metals (e.g. Titanium, Chrome) guaranteeing a great resistance to wear and corrosion.

    This unique treatment, grey pearl in color, extends to the breech bolt group, the trigger and the carrier.
    The main internal springs (recoil spring, magazine tube spring, valve spring), the self-compensating valve and the rear drop/cast plate are made of stainless steel. The homogeneous matte black finish, which characterizes all the metal parts in view, boasts anti-glare properties.

    MINIMUM RECOIL, MAXIMUM PERFORMANCE
    Gas Operation System with Exhaust Valve. The unique gas operation system, patented by Beretta, with self-cleaning gas cylinder and piston, is provided with a self cleaning exhaust valve that automatically vents the excess gases of the most powerful cartridges.The result is that the shotgun, without any adjustment, fires everything from the weakest 28g (1 ounce, 3 ¾ dram equivalent) game load to the heaviest 64g (2 ¼ ounce) Super Magnum cartridge. The exhaust valve remains attached to the barrel, ensuring easy and quick assembly and disassembly of the shotgun.

    New Kick Off® Recoil Absorber
    The new Beretta patented Kick Off system  has been conceived to further reduce felt recoil when shooting. Thanks to the Kick Off device, the recoil energy is gradually dissipated by two hydraulic absorbers  inserted into the stock. The result is superior comfort for the shooter. At the same time, the vibrations and the muzzle jump when shooting are strongly reduced.

    Recoil Reduction System. A spring-mass recoil-reduction system, located inside the stock, counteracts the rearward forces generated by shooting and greatly reduces felt recoil.
    Bolt Travel Recoil Absorber. Manufactured from an advanced elastomer, it reduces the vibrations transmitted to the shooter and contributes to the shotgun’s reliability and durability.

    Adjustable Length of Pull. Thanks to the two stock spacers (one assembled) the length of pull of the Xtrema2 Standard model can be adjusted to all shooters.

    Gel•Tek Recoil Pad. It reduces felt recoil and vibrations transmitted to the shooter and is interchangeable with extreme ease.

    Rotating Bolt. The rotating bolt with two locking lugs guarantees maximum safety and reliability even with the heaviest cartridges. The operating rods are integral to the bolt body, ensuring that it is guided symmetrically and with minimal friction. The disassembly and reassembly of this unit is also simplified.

    Optima-Bore Barrel.
    The Optima-Bore internal barrel profile features an overbored diameter and lengthened forcing cone that considerably improve shot pattern distribution and felt recoil reduction.

    Optimachoke Plus Choke Tubes.
    The Beretta Optimachoke ,Plus tubes feature a long, gradual constriction, internal profile formed to minimize shot deformation and to enhance the concentration and distribution of shot patterns. Engineered to resist steel shot stress and corrosion.

    RICH ACCESSORIES

    The Beretta A391 Xtrema2 shotgun is supplied with a modern design case and a complement of accessories: additional set of stock drop/cast plates, 25 ml. Beretta Gun Oil, set of Optimachoke Plus choke tubes with spanner, stock spacer with assembly screws , front and rear sling swivels.

    Stock Drop and Cast Spacers. They allow the stock drop and cast to be adjusted by simply
    modifying their assembly position.

    Quick Detachable Sling Swivels. Thanks to an exclusive quick-release system it is possible to fasten
    and remove the rear swivel from the stock without any tools.

  • The Nike Mercurial Superfly II Elite (in depth analysis)

    The Nike Mercurial Vapor Superfly II Elite

    Original Color for Superfly II Elite

    Personal Point of View on the Shoes

    Theses shoes over the past few weeks have left somewhat of a great impression on me. I’ve looked at them, held them and been given a quick trial with these shoes. I have a love hate relationship with these boots from personal experience alone, but completely understand why these are the top and newest shoes on the market right now. I wouldn’t call them the perfect shoe for me, I’ve tried somewhere over 20 football shoes in the past 5 years and I’ve come to learn that all shoes have advantages and disadvantages and depending on the person, the shoe could suit different people in different ways. These shoes from my own knowledge are by far the lightest I’ve ever tried. The lightness of these shoes contributes to why they are so popular, it made me run faster and accelerate quicker, and in a sport which is played so quickly, speed is of a high priority. I personally think that these shoes have been well designed in the aspect of visual attractiveness, because when I walked into the shop they were the first shoes that came into my view. Certainly they are attention grabbers, and being in the middle of the field it’s quite important that my teammates know where I am.

    Nike’s Stated Benefits of the Shoes

    • Flywire for ultra light-weight and support

      All four shoes of the Nike Elite series introduced for the Fifa World Cup 2010
    • Revolutionary traction for extra grip
    • Traction pattern for cutting and instant acceleration
    • Includes exclusive shoe bag and box
    • Firm-ground (FG) Bladed and conical cleats for use on short grass fields.

    Nike’s revolutionary traction in Nike’s opinion is the top reason for the shoe’s popularity. The traction in this shoe is

    Cristiano Ronaldo endorsing the new football shoes

    what is called ‘adaptive traction’ that activates a cleat in the forefoot that extends when enough pressure is exerted, it extends when needed for the “relentless grip and acceleration the game demands.” Along with the injected stud, the traction in the vapor allow for effortless acceleration. The shoe also includes toe off traction for instantaneous bursts of speed.

    All fields of the aesthetics and materials were carefully chosen and for specific reasons. The Vapor Superfly II Elite features innovative Flywire. Flywire is made of nylon fibers, these fibers are sturdier than older materials and help hold the foot in position. Another advantage to Flywire is that the mass of the material is a lot lighter than older materials. The Flywire also provides better control of the ball and adjust to the foot a lot better. The most minimizing factor of weight in the unparalleled lightness of these shoes is the carbon-fiber chassis, which makes the shoe lighter but also at the same time maximizes strength. The final major contribution to making these shoes such a success was the perforated sockliner which presents low profile cushioning and support whilst also lessens the cleat stress. The total weight of this pair of shoes is an amazing and currently unmatched 370g (13 oz). This boot is favored by wingers or strikers who feel that speed is the most important asset in their game. As a publicity stunt, Nike got Olympic Gold Medalist sprinter, Asamfa Powell, to run 100 meters in these football shoes and on the first attempt he covered the entire distance of the football field in less than 10 seconds, four tenths of a second slower than the track world record.

    Part of Nike Elite Series

    After spending nearly 2 hours in the store I came to the conclusion they weren’t the shoes for me. Instead I chose the T90 Laser III, also from the same elite series. The new revolutionizing elite series consists of 4 shoes. The first, as I have discussed previously in depth because they have been the biggest success and most sophisticated technology, was the Superfly II. Secondly was the shoes I purchased, based upon personal preference, the T90 Laser III. Thirdly, the Tiempo III, these boots are more intertwined with the classical designs of the previous years, but still incorporates much of the revolutionary technology. The final pair is the CTR360, which is the sturdiest of all the shoes, and as the name of the shoe states it optimizes control of the ball. As I have said before the choice goes down to preference but all these shoes have their given benefits and a choice of any of these would be a choice of a football shoe that has left its mark in revolutionizing the football industry.
