Just finished the upper, came in at 58.4 ounces. With the lower at 18.6 ounces
total weight is 77 ounces or 4.8 pounds.
I have to shoot it ASSAP, just so many projects at home.
In order to get down to 4.5 pounds I would have to have a 16 inch barrel weighing 29 ounces.
I know Salt Works has done a demonstration barrel at that weight. Maybe Faxon will produce a true pencil weight 308 barrel.
Also really want a lighter CF pistol grip. At 1.1 to 1.3 ounces it would cut 0.5 to 1.0 ounces over must grips.
They are now making titanium carrier pins for the AR15, logical to also make them for the 308.
