The Beretta CX4 Storm Polymer Picatinny Rail Kit adds serious modularity to your CX4 Storm carbine. If you're running the stock side rail and want to flesh out your platform with optics, lights, lasers, or a vertical grip, this kit gives you the bottom rail position plus two additional side rail segments—letting you configure your rifle exactly how you shoot it. The polymer construction keeps weight down, and all three rails are Picatinny-compatible, so they accept any standard Weaver-mount accessory.
Whether you're setting up a carbine for home defense, sport shooting, or tactical training, modularity matters. The CX4 Storm already offers a compact, controllable platform; adding rails lets you optimize it for your mission. The kit arrives with four mounting screws and installs directly onto your existing CX4 frame.
Polymer rail systems like this one strike a balance between weight savings and durability. The bottom rail opens up ergonomic options—vertical grips, handstops, or bipod mounts—while the side rails let you keep your preferred optic and light within easy reach. Build it once, build it right.
| Manufacturer | Beretta USA |
| Material | Polymer |
| Finish | Black |
| Rail Configuration | Bottom rail, two side rails (Picatinny) |
| Mount Type | Weaver-compatible |
| Mounting Hardware | Four screws included |
| Firearm Compatibility | Beretta CX4 Storm |
Any accessory with a Weaver mount—including tactical lights, laser modules, optics, vertical grips, handstops, and bipods—will attach to the Picatinny rails on this kit. The bottom rail is especially useful for underside-mounted vertical grips or supports.
Yes, this kit is designed specifically for the Beretta CX4 Storm carbine. It works alongside the side rail provided with your carbine to add the bottom rail position and fill out the remaining side rail slots.
The kit includes all four mounting screws needed for installation. No additional hardware is required.
Polymer keeps your CX4 Storm as lightweight as possible while still offering full Picatinny compatibility. For a compact, maneuverable carbine platform, that weight savings can matter—especially if you're running optics, lights, and grips on multiple rails.
