What is the inside diameter of the large end of the taper at the rear of the 5/8 adapter?

Approximately .675". What rifle are you building or buying?

It would be for a hunting rifle with a skinny sporter profile barrel.  The general rule I have read for 90* shoulders is they have to be .100" larger than the major diameter of the thread, as in .725" for 5/8.  It sounds like using a Sig taper and this new DT adapter of yours opens up more possibilities for thinner barrels.  If a .675" barrel OD will get full taper engagement into your adapter, that's a win.
