I can't take near the quality photos with my cheap arse digital, but this shows the original, and the Wolff set up. I don't know if the one's that they sell today are manufactured the same or not. I've got over a thousand rds. on this Wolff set up, and it's still super stiff. I think I bought the spring setup in 2009 or 10. That cup that the rod rides inside of, I believe is plastic. It has a weird feel to it, and is hard to distinguish between a metal and plastic, even with wear marks on it.
