Just as a point of reference, I weighed my Stevens 200 just now; it's a SA (in .308) with one of the FDE Tupperware stocks, a DNZ one piece mount and a Nikon Monarch African 1-4. 7 pounds 3.125 ounces.
Getting one of these sub six pounds could be a fun project, but IMO going below that will take a lot of work!
