So many great lightweight rifles available today! My short list is as follows, choose based on your available budget just how Uber light you want to go and stock fit.

NULA
Barrett Fieldcraft
Kimber Montana, Mountain Ascent ect.
Savage Lightweight Hunter
Tikka Superlite

For me personally the CLR/NULA hybrid is the perfect answer all up weight 7lbs 3ounces (rifle scope ammo sling) the stock fits me so well and they are the most consistently accurate rifles with multiple loads.

A step down big time in price I like Tikkas and put up with their factory stock. One day I might get a McMillian for my superlite.
