It requires a bottom metal. Best to go with AICS mag style. There are several brands available. Quick google search.
What Savage 110 are you building? Short or Long Action? Do you have a newer or older Savage? Makes a difference for being Center or Stagger feed. I’m more of a chassis user myself. Do you have a strong preference for the Hogue style stock? If not, you might want to look at the Magpul stock. It’s kind of a hybrid. It’s a Stock, but is very stiff, and already comes with the bottom metal & uses an AICS magazine, like a chassis. (Includes the mag also.) However, I believe it’s available for SA only. Or, a Chassis perhaps?
