what armorers tool to remove stock barrel nut on M&P10

[kenbob204]

I know this has been asked before but I have been through a bunch of forums and I am still confused on the size/pattern barrel nut and not sure which wrench to buy. I have a free float hand guard on its way and I need to remove the stock barrel nut to remove the delta ring. From going thru the forums it seems like stock barrel nut is DPMS.

So I thought this one would work but in the description it says "This wrench will not remove DPMS Delta ring barrel nuts."

DPMS/KAC 308 barrel nut torq wrench:

So would this be the correct one?
Barrel nut torq wrench for AR10:

or would it be this one?
Armalite 308 combo barrel nut wrench:

or would any DPMS tool work like this one?

It is the same size as a standard AR15 nut on the wrench. My cheap wrench worked.
