Hi I got some piston rings for a malossi 172 piston but they don't fit right. They are meant to be the right size so they should fit. https://youtube.com/shorts/7cwoJWc0jCM?si=qtkIOKgKU0TU1-rJ

I've just watch a video on YouTube and I found the rings was the upside down.

Glad you found the problem.

Yeah if they trapezoid, they go one way…

Should be a mark on the ring next to the opening. Something like "N, or top" should be lazered onto it
