*Beretta Cx4 Storm Info*

The Beretta Cx4 Storm is a pistol-caliber carbine aimed at the sporting, personal defense, and law enforcement markets. It is available in two models: one that accepts 92/96 magazines, and one that accepts Px4 series magazines, each available in 9×19mm Parabellum, .40 S&W, .45 ACP, and 9×21mm.

The Beretta Mx4 Storm is an automatic version of the Cx4 Storm.

The Cx4 Storm was developed to be used in conjunction with Beretta semi-automatic pistols. For example, the magazines for the Beretta 92FS chambered in 9mm can be used in the Cx4 (also chambered in 9mm). This aids in a smaller loadout – no longer needing to carry separate magazines for the rifle and handgun – and adds redundancy, allowing a person to carry more ammunition without adding weight.

The Cx4 comes from the factory with adjustable iron sights. The front post sight is adjustable for both windage and elevation using the supplied adjustment tool. The rear flip sight has two apertures for snap shooting and long-range elevation selection. Both sights can be folded down when optics are mounted to the optional top rail.

The stock on the Cx4 has an adjustable length of pull. Adjustment is made by the use of stock spacers. The carbine comes with one spacer installed, which may be removed. With no stock spacers installed the minimum length of pull of the Cx4 is 337 mm (13.3 in). To increase the length of pull, additional stock spacers may be purchased separately. A total of three stock spacers may be installed which bring the length of pull to a maximum of 382 mm (15.0 in).

In addition to being able to customize the Cx4 with accessories, it is also able to switch the safety, cocking handle, ejection port, and magazine release to the left side of the weapon to accommodate left-handed shooters.

    If you are wanting to remove the barrel on your Beretta CX4, this is exactly what you need. A top quality tool made to fit the exact dimensions of the slots in the Beretta barrel nut and it made my job of taking the barrel off a “no brainer” . I would give it ten stars if possible.

    This is probably a dumb question. With the tool pointing up, which way (anti-clockwise or clockwise) should I turn my wrench? I was leaning to anti-clockwise but the nut was so tight that it doesn’t seem to turn a bit. I was too scared to force it either way. Just don’t want to damage the nut. Please help. Thanks.

      The barrel nut I have on hand for QC purposes looks like a standard right-hand thread so anti-clockwise should be correct. It’s possible Beretta uses some thread locker on the nut so you may try a little heat to loosen it up. A heat gun or even a hair dryer would probably do it. Probably don’t want to step up to a torch because of all the polymer around but that’s your call.

    Great tool and great after sales service. Brilliant idea using a heat gun and confirming the right-hand thread. I turned anti-clockwise with confidence and the nut DID come off !!! Thanks so much.
    But the barrel is still firmly stuck with the polymer around it and doesn’t seem to twist a bit. I wonder if there’s more holding it down. But it is not a NAAH tool problem anymore. This is the right tool to remove the nut for sure.

    Apart from the barrel nut, is there any other parts that is holding the barrel to the polymer frame anyone knows of? I would like to buy extra parts needed to separate the barrel and the polymer frame. Thanks.
