I have the props files . I don't know how rig the figure . The file are fbx . I import the file into 3dxchange . The files load with no problem . But I don't know how to rig and shoot the gun on its own like I want to . 

Could you possibly post a screen shot or two of the situation, and also explain a little more about the self firing action that you are looking to animate?
