This came off of a Savage 110 Tactical. I pulled it off almost immediately and switched to a Magpul Hunter stock. There is nothing fancy to this, but it does accept AICS magazines (including those from Magpul). It has all the Accu-Fit spacers and screws. If you're using a top-feeder or have those old chintzy clip-in magazines that Sagage continues to produce, this is an improvement.
