The Beretta Mx4 Storm is the military version of the Beretta Cx4 Storm[1] pistol-caliber carbine. It has a barrel length of 12 inches, and is capable of automatic fire. The Mx4 can use pistol magazines, or its own 30-round magazine. There is an accessory rail on the top of the Mx4 for mounting scopes, laser aiming devices or flashlights. There is another rail underneath, forward of the trigger, for mounting vertical foregrips, laser aiming devices or flashlights. The Mx4, with a scope, is fairly accurate out to 100 meters, and automatic fire is accurate out to 200 meters. The Mx4 has a reputation, among the many police and security personnel who use it, of reliability, ease of use, and handling[citation needed].
