Gas rings wear out so they are a "regular maintenance" component.
Their cheap and easy to R & R , and yes making sure the rings separations are not aligned DOES matter.
(If they are all aligned, gas will escape and weaken throwback.
I found this vid which is pretty much my SOP.
Yeah, I consider the gas rings a "regular maintenance" component. Similar with other items like many springs. Specifically for the BCG, the extractor spring and ejector spring. Just haven't changed them out yet. My older higher round count gun, I ended up selling off, so my current guns are all well below 5,000. I do have an extra bolt and extra BCGs, but not the springs. I've been meaning to get them since I've been shooting more lately, but just haven't done it.
I'm surprised that they guy's gas rings failed the BCG test at 3,000 rounds. I think my highest round count AR and BCG is now close to 3,000. I'd have to check. I wasn't planning on doing anything until at least 5,000 rounds.
Gas ring alignment? Haha. So many folks arguing about it. I don't particularly pay attention to them, but I've heard of some OCD folks to tend to align them when cleaning their guns.
