J.Baker is right. You'd probably save money getting the action from NSS, barrel from NSS also, and the stock from Stockade.

I know this is blasphemy on a Savage forum, but I've come to the conclusion that Savage actions aren't that great to build lightweight rifles. I think Remington and Tikka actions are lighter and have more and lighter aftermarket parts available.

You could buy a Remington action, and have a Remage barrel nut system done. Then, you could screw on your own light barrels. The Remington action would let you use a 14 to 18 oz stock from MPI or Wildcat.

I could be wrong. But, my evidence is forums like Rokslide, where there's a lot of elk hunters trying to build or buy the lightest rifles. You won't find many elk hunters building a lightweight rifle from a Savage action on Rokslide.
