The CX-457 is JNDynamics first innovation in weapons technology that really hit the markets and made JNDynamics a known name. It is a battle rifle, which can be turned into an all-purpose machine gun on the field with the correct tools. It also features a shifting counter weight to help control recoil. This, combined with the weapons moderate weight makes the 7.62x51 round kick like a puny 9mm SMG. There are kits for M249 Light Machine Guns to turn them into a CX-457, or you can buy them as a whole from JNDynamics.


No country has put this gun into service, while it is highly popular amongst Private Military Contractors.
