Since I am planning a ZC review later this year and the 36mm ring situation is an important factor I spoke with an number of companies about 36mm options. Here is what I heard:
Bobro - Andrew is in wait and see mode on demand. He can do it quickly and easily if he decides that way but he is not sure if enough demand will materialize.
Spuhr - In addition to the 0mil and 16mil 1 pc bases (I think these are both 1.5" height) he currently has there will be a 1.18" 20moa and a 1.5" 20moa 1pc. There will also be some in the new line of lower priced, lighter, hunting mounts.
Badger Ordnance - Actually used to make some 36mm when the Hensoldt came out. Wasn't enough demand to keep doing it. If there becomes enough demand they will start again.
Seekins - No plans for at least 2019. Sure they can change after that if enough demand comes but they doubt it.
MPA - They currently make a 0MOA 1 pc. They are considering adding a 20MOA
APA - 35mm and 36mm rings are on the to-do list but expect a year out as they are not at the top of that list.
Hawkins - No 36mm plans at this time.
So, there are some new choices in mounts that will be coming out in the near future. Between Spuhr and MPA you should be able to get a 20moa before too long. Spuhr may also add some more lightweight ring options from their hunting line.
