Huma Reg For Impact

Hi All,

So I have few guns, and when I buy accessories I usually buy a few to go into all the guns I have, I just installed a Gen3 Huma reg into my ImpactX and it occurred to me that I need to get o rings for the new reg.

I have mild OCD, I can't handle not having spare parts, even if I don't immediately need them. Does anyone happen to know what the sizes are for the rings that are on and inside the Huma? I could open her up and measure, but the rings inside the reg body require you to pierce the oring to get it out to measure. I figured that before I go all commando on the reg maybe it was a better idea to ask the community for their collective help!

I have sent a mail to Huub asking the same but I thought that I would post here as well...
