Probably a flat-back, staggerfeed (magazine affixed to action) model.
If so...get a new barrel, an aftermarket recoil lug, a Rifle Basix SAV-1 trigger (though the old 3-screw triggers can be tuned pretty nicely) and the stock of your choice. Manners & McMillan make good stocks, the Choate Tactical is a decent budget option, Stockade is another possible choice for you, and I think XLR/McRee have Savage LA chassis available with MDT releasing theirs in the next few months.
