JSAR O-ring size?

Maybe post on Gta, travis owns it and posts there daily i think.

I didn't know Travis owned GTA. When did that happen?

There is a thread there started today asking for some o-ring sizes. Nothing concrete yet.

I would love to have a schematic with a parts list for future repairs etc.

Maybe a month ago or so.
 
I blew one out on my new .25 JSAR. I called. I emailed (twice). No response. I finally messaged them via Facebook and it too respond. 
The finally responded today with: "You need a -009 O-ring for that location" - which may answer your question. Not sure if this is the same for your rifle in .30, but that's what they said for my JSAR.

The O-ring looks and feels like silicone, not rubber - so I'm going to try a silicone one.
