Anybody know the o-rings needed to rebuild the Huma reg? I know the outer o'ring is a 19x2.5, but need to know the other ones. I guess it's (4) of them? (1) between the reg and spacer, (2) on the piston and (1) on the adjuster?
I just picked up one used and already put it in the gun. I should have just disassembled it and measured but I didn't.
