Rare as hens teeth, but there's a handful of Brown FS stocks out there. I've seen three pop up in the last two years, I picked up one of them and it completely changes the characteristics of the rifle (mine is just the standard Model 7 SS)
Even rarer there's a couple McMillian KS short action stocks out there.
You can also order a McMillian Edge, I think I've seen one of those on the used market.
I'm sure there's another few options out there to save some weight as well, but those are what I know of.
