New info.
ARMS, LaRue Tactical and Austin Precision have not answered my emails so far. Maybe my email system is bouncing and in that case this is a good place to comment.
Precision Reflex Inc and Near Manufacturing have answered in a swift and professional manner. PRI has a .59" high ring set for 34mm tubes made out of phosphated steel $154/pair. Near has only low rings made out of SS and blackened for 34mm but did offer to make a custom one-off set for me with a a long waiting list but not too steep price considering they would have manufacrued one set with my specs only. Ok, I would be able to buy two sets of their regular off-the-shelf items for the price of this custom set but I consider their offer as fair given the extra set-up costs, headaches etc. during the manufacturing process.
I am now considering PRI rings as they seem to be the only game in town that both has products and wants to answer my questions. If anybody has any opinions on PRI scope ring quality I would gladly hear about them. I suppose the quality is the same on 1", 30mm and 34mm rings so any comments on their rings would be worthwhile.
