What is the bolt size that this head mounts up to. My department issues bog tripods and I am tapped out on money after fitting the bill for the rifle and other equipment. I have found an adapter to change to a ball head. What I am wanting to do is put the invert 40 head on the adapter and when I am able I will buy the legs. The adapter uses 3/8-16.

If the fatboy does not work with the adapter what is another good ball head that will fit this adapter. I am trying to not just throw money away and still make the best of the equipment issued.
