I have Gen I,II & III. Stocks aren't impossible to find, but you need to know what action you have, exactly. Accurate Mag also makes bottom metal & magazines for Savage too.
Gen I: I'v two, SSS Fiberglass composite w/ full aluminum bedding block (223 Rem heavy), relatively light, awesome stocks, 1 one is available, if anyone needs one
Gen II: I'v a Choate Tactical blind box(6.5CM heavy), solid plastic (heavy, sturdy) w/ a full length bedding block, excellent and a bit on the heavy side 3.5lbs, You want a stable Sav stock and not a chassis guy, get this and the price is great. [have also for SAV110 and Rem BDL]
Also: An XLR Element Gen1, (6mmCM bull) that if I remember, will also fit Sav GenI short, but it was discontinued and XLR has the Element 3.0.
Gen III: I'v an MDT Oryx, pimped with all options for an FV (25CM bull), it's heavy.
My 10BA Steath (6.5CM) came with MDT LSS chassis. It's alright, change out the crap stock & grip asap.
Also: Boyds thumbhole laminated, waiting for an action.
