On the bolt itself there are 3 gas rings. The manual says to stagger the gaps 120 degrees, but has no specification as to how tight they should be around the bolt. When I was cleaning the bolt I noticed one of the rings crept up the bolt a little, so I pushed it back in place. Now I can't help but think I brushed them out of spec and need new ones. Does anybody have any insight to this? Thanks in advance.
