There is no way to say which unit used what weapon by the serial number block ... The only positive way to do this would be paperwork with the weapon and this would not be common at all.

I would also suspect that were Légion étrangère rifles identified with a specific serial number block, fakes would rapidly abound.I suspect declaring a French firearm to be "Foreign Legion issue" has the same cachet as declaring a U.S. firearm to be "USMC" issue.
