Need to Source Fill Probe O-Rings for my Artemis M11

[DrGunner]

Would anyone happen to know what size the O-rings are on the SPA M10-11 fill probe?
I’d like to buy some high-quality ones and just have done with it, on my second fill of my new rifle one of the O-rings on my fill probe Developed a small Nick, when I went to remove it it just broke apart from dry rot. I had a replacement that came with the rifle, but I’m thinking I’d like to have some on hand just in case. I’d also like to pick up a full O-ring seal kit for the rifle- It never hurts to stockpile wearable parts. I found an outfit in the UK that makes a really nifty custom dust cover for the fill probe holes. Sure would be nice if I could find a US source for the fill probe O rings, the seal kit, and a dust cover like the one on this site:

Any info, especially links that you can provide will be appreciated

The P12s take 6x1.5mm o-rings on the fill probe.
