Ok, now I’m confused again. In this picture that second ring has the bevel facing down. And that ring, the way it’s installed in the picture says TOP on it and the TOP is up?

If that’s what it is that certainly must be the way they go because you wouldn’t want that ring in the top groove.

I‘m having a hard time getting my head around why no bevel for the top ring. That’s crazy IMO.

It's just a cheap set of rings. So I actually found this quote on motor trend (not that they don't publish garbage all the time but it's at least something)

"Usually, the rings are bevel-cut to promote twisting. The top ring is often beveled on its top inside edge, which causes positive twist. That pushes the lower inside edge against the ring groove and creates an oil seal, while also allowing cylinder pressure to get behind the ring. The bevel of the second ring is machined in the lower inside edge to create negative twist and press the lower outside edge of the ring face against the cylinder wall for oil-scraping"

So given only one ring has a bevel, and it's on the bottom edge, I am keeping that ring in the second groove.
