There is probably a reason it is banned, il look into it, but keep in mind we want 2 weapons and a terrorist and swat model for the first version, lets work on that first and forget the rest, for now.
http://www.impactsites2000.com/site3/class3_10.htmDone some research to the weapon and my conclusion:
Its utterly crap, if you want to defend yourself against a well trained police team then you do not want to pick this weapon, it has a terrible aim and recoil, its is a simple weapon and is mostly operated by people whom do not have the skill to operate anything other, the weapon is only suited for mass murder and is therefore banned in Amerika.
