There will most likely be many adresses/values. Like the one of texture, model, amount of ammo and mags (it has changed), animation, features ,etc etc, important is to find the value that defines the class M16 (or any other wpn if you like), this value will "hopefully" (if they haven't deleted it to make it harder for cheaters, but they are lazy, I doubt they have done so) affect the other values and adresses.
