I've created the pre-fab for the Modern Assault Rifles listed in the Equipment Guide. I did not include any of the "never produced" rifles as they usually had some quirk that I could not calculate in the Hero Designer. I also did not provide any monetary costs for the equipment -- I will leave that up to the campaign owners to account for.
I was not able to replicate the costs calculated in the guide, but I did use a consistent methods as described the various rule sets. On the whole, the relative costs compare well with the guide book.
Comments are welcomed.
