I just ordered a set of ARC M10 30MM low rings from Short Action Precision last week. But the height you are requesting are the "extra low".
Be aware, dependingbon your rail set up and scope choice, some scopes will not clear a full length Picatinny rail without hitting the center turret bell, unless you mill down the height of some of the slots.in the center. Swarovski is one that comes to mind. You need medium high .92" to clear.
