At some point, I figure I'll want to upgrade the stock.
As setup from the factory (DBM, bottom bolt release), these are the options I've found. All are going to add weight over factory stock.
HS Precision:
PST129 - Advertised Weight 3.05lbs
PST137 - Advertised Weight 3.95lbs
Manners:
None for long action - per email from Manners
*Short action yes, must order w/ mini chassis
McMillan:
Just one: Mcmillan Savage HTG - Advertised Weight 2.5Lbs
You will have to ship the barreled action and bottom metal for custom fitting.
Per email w/ McMillian
B&C:
Savage Sporter Style - Model #1017 - Advertised Weight 2.25lbs
Likely need to open up the barrel channel a decent amount.
Stockade Stocks
I didn't research enough into these yet. All feedback says they're heavy but quality.
GRS:
Bifrost - A chassis/stock hybrid.
MPI Custom Stocks
This is the only option I can find where you could actually maintain or even reduce weight on the rifle stock. "Sportac" model would be my 1st choice. I'd plan on shipping rifle to them and doing "Complete Restocking ($895) and opt for the "Lightweight Kevlar" option (+$100). With shipping this option would run as much as the rifle. Probably more, as I'd probably upgrade the bottom metal (PTG Stealth or ???).
Boyds:
Many models in a laminae/wood stock.
*Boyds is installing pillars now. Only doing front pillar for this savage.
The "Spike Camp" model with front pillar for $155 has peaked my interest.
About 2lbs.

Laminate stocks
Note:
*In general, Short Actions have way more options but I didn't spend my time on that.
Chassis:
Multiple available but not on my radar. AICS mags could gain some COAL above the ~3.5" from factory magazine.
