My S308 weighs in at 7.8# as pictured below.
I have owned .308's in an AR-10, FAL, GALIL S-308 and HK91.
S-308 - the most economical, lightest and most utilitarian...
AR-10 - the most accurate,.but most expensive. (Kinghts Ind). Also the most sensitive to dirt & fouling.
Galil - the most fun and coolest and best resale, but mags are the most expensive and hardest to get (>$100 each). Pretty heavy too at about 11#.
FAL - the heaviest (11.4#) and longest OAL with 21" BBL, but cheap mags (~$4 each).
HK91 - the most painful to shoot with a collapsible / folding stock and hardest recoiling, but cheapest mags (<$3 each).
