I don't have the email anymore but when I asked them a while back they said that for whatever reason the savage action would not work with their design. With so many other options out there, I don't see enough interest for KRG to try to redesign whatever portion of the stock that makes it unusable on a Savage action.

MDT just released the new XRS stock/chassis and will have a Savage inlet released soon. Honestly, at least for what has been released so far, the Bravo seems like a better product with many more accessories and options. You can pick up a Bravo and a couple of accessories for the same price that the XRS is supposed to sell for. I like MDT products, but at least right now don't see why someone would choose the XRS over the Bravo. Other than for the fact they don't make the Bravo for Savage.
