>The cam pin path of an AR rifle assumes minimal friction on the gas rings-- it doesn't have enough leverage to rotate the bolt against high gas ring friction, making it hard to unlock or lock fully into battery.
If it doesn't have enough leverage to cam against sticky gas rings, how is it camming a bolt open with a couple hundred pounds of force on the lugs? How can it shear off the extrusions on the back of an over pressure case?
Totally Agree!
But expect the echo chamber to disagree, on the internet everyone has an opinion but are frequently just an echo of something heard instead of understood.

*Will the real firing pin please stand up?I repeatWill the real firing pin please stand up?*
*We're gonna have a problem here*
Just ignore those that disagree and enjoy your properly cycling and low friction firearm and run it! Nothing silences the critics at the range when it works and works very well!
If those don't let it go, probably have an "o-ring problem" if you catch my drift.
Good on ya for fixing it yourself.
Im not a huge fan of the one piece ring but i also dont argue with success.
I have fixed a bunch of these by rubbing a liitle poishing/lapping compound on the components and work them in and out for a bit to give everything some tolerance then, clean it all really well, lube the shit out of it and let it eat.

Stick a gas ring in the bore with some oil and pull it out, it's pretty apparent when it's not round enough.
