@ Vespers War - I don't know if you visit Maxim Popenker's site about military firearms but he recently (although I don't know exactly when) added the TuF to his pages.
The stats he's posted are like everyone else's - sparse due to the lack of more more comprehensive info but he does separate weights for the gun and its carriage. I think you probably already have this data but here's the link in case you want to check it
