CX4 Storm: A Tactical Carbine with Pistol-Like Controls

The CX4 is a semiauto pistol-caliber carbine designed to give you the familiar controls of your favorite Beretta combat handgun.


It is perfect for shooters who are already familiar with Beretta tactical pistols, or more in general for those who may not have extensive experience with a rifle or carbine. However, the cold-hammer forged barrel delivers the sort of accuracy that even the most experienced shooters will appreciate. Easy to use, ultra-reliable and low-recoil, it has been adopted by several police agencies aross the US, while its versatility and accessorization options have made it a favorite of recreational shooters. Whether you use it for home-defense, varminting, competition or training, the CX4 will deliver what it promises.

Full-Size-Pistol-MagazinesAccepts Beretta Full-Size Pistol Magazines

The CX4 is adaptable to accept any full-size Beretta PX4, 90-series and 8000 series magazines (using optional adapters), thereby saving existing Beretta users the expense of additional magazines. Along with its uncompromising Beretta quality, this is an additional reason why the versatility of this carbine is highly prized by tactical shooters. Along with a Beretta pistol, it helps create the best and most versatile tactical system available today, as evidenced by the CX4’s dedicated following.


Extremely Versatile, Easy to UseEasy-to-Use

This light and compact carbine was designed to be completely and easily adaptable to the needs of most shooters. The operating handle, safety and magazine release are reversible and give you the opportunity to train or shoot right- or left-handed, while case ejection can also be switched from right to left. The length of pull is adjustable (one spacer included), making the CX4 easily and intuitively come up to the shoulder of most shooters. The aperture and post sights are user-adjustable, meaning that you can train with (or switch) your favorite brand of ammo without taking the carbine to a gunsmith. And after a day at the range, this carbine is a snap to take apart and reassemble, while its ultra-tough construction and surface treatment make it stand up to the hardest use.

Easy-AccessorizationEasy Accessorization

The CX4 just begs to be accessorized. Between the front and rear sights, it features a full-length aluminum top rail for mounting optical and red dot sights. It also sports a retractable Picatinny rail that extends from the fore-end, which allows users to mount tactical lighting devices and other accessories. Additional rails can be mounted on the left, right and bottom, thereby providing ample opportunity for customization. Please visit our accessories page for a full list of CX4 accessories.
