JTS airacuda max o-rings

I have the Airacuda Max .30. I need to replace the o rings. After reading all the forums I want to get highly quality o rings. Does anyone know if the rings are the same size for the .30 as the .22 and .25? There is no parts list with the owners manual and measuring with a micrometer is a pain. It’s is unresponsive so far Ste 3 weeks of emails and phone calls.
 
there are large assorted size o-rings in metric on amazon . wish I had a better answer . also firewalkers post above
Yeah. I ordered a set. They are all too thick in material for the diameter needed. I also noted that they are BUNA N70. Ideal according to what I have read for static locations in the rifle. The spare set that came with the rifle is hard as rocks. My experience with other o ring applications tells me not to trust them. They might have sat on a shelf too long. The owner's manuals for the .22 and .25 shows a very clear breakdown of location and size. That is why my question regarding the parts for the .30 is. Are they the same size in the rifle .30 excluding the breech where the calibre comes into play? I looked at Bagnall and Kirkwood. They don't show the sizes and again exclude the .30.

You can see the parts breakdown here if you don't have a manual for the .22 and .25
