OK so I spent 45 mins searching:

savage 12 and savage 10 bottom metal the same?

But I can not find the answer I'm looking for. Anyway, there's a choate stock 4.4 spacing for sale for $225 shipped (is this a good deal?) with bottom metal and a magazine but my dillema is, I have a savage 12 in 223 and the stock for sale is from a savage 10 in 308. My question is, can I remove the bottom metal I have on the Savage 12 and put that on the stock? Is it the same dimension? Or can i just swap the magazine and Am I good to go?

Thanks Folks!!!
