Have no idea if it has the metal rings, I know they phased out the metal to O rings sometimes during the production cycle. I think in comparing vintage guns we often compare well used guns, which don’t reflect what standards at which they could originally performed?

Interesting I have several Hy-Score all in very good shape. They all shoot in the low to mid 400 fps except for the above Sporter which is 500+. Curious to me? Is a short barrel good for spring gun speed? But my other short barrel is low 400’s. Could just be the random spring, or this one just seals better in the loader?
