KRG (Kinetic Research Group) has announced they will be offering their Bravo hybridd stock/chassis for Savage S/A's with shipping starting sometime this month (Dec. 2022).

I run one of these on my ARC Nucleus build and I know TxHillbilly has been running one on his for a few years now as well. Unfortunately KRG won't be offering a LH option for the Savage's at this time, but I'm betting if we hound them enough we might be able to convince them to.
