Is the Model 111 FCNS 30-06 w/ Accustock & DBM staggered feed or center feed

Hi all,

I am researching after market stocks. I want to rebarrel a Model 111 FCNS with a heavy barrel. I'm told it would require a wider barrel inlet and that I should look for an after market stock. No one seems to make a stock with a full metal bed that can fit the new model 111 FCNS Accustock 30-06 with a DBM. In my search I see that there are different "feeds". What is the difference between center feed and staggered feed? What feed does the newest Model 111 FCNS 30-06 with Accustock and DBN have?

Thanks.
