This is a simple way to get more control over the front of your CX4. It attaches in the same spot as you would put a factory picatinny rail on the side of the firearm. Taking many styling cues from our CX4 light mount we made this ergonomic and easy to use while still remaining unobtrusive and sleek. Perfect for pistol cal carbine competitions. It does not, however, come with mounting hardware since Beretta thought it pertinent to make those screws a very odd metric size so you will need to bring your own to this party. These also come with a laser cut grip tape section to further enhance grip if need be. As always these are 6061 that is Type 3 hard anodized.
