Stock question

[joeb33050]

I need a factory tupperware stock for a .223 Rem Savage 12 FV with 4.44" screw spacing. The stock has what looks like the innards of a magazine in it. I need to know what this is called so I can ask here for the right stock Center feed? DBM? I don't know what all those mean. What is the correct term for this stock?
Thanks;

I think I have one but the barrel channel is for varmint contour.

WBM, I think his has a varmit contour so it would work.

My rifle doesn't have a separate magazine. If you have one, $?.
