Hey all

Just wondering how to ID the rings for my Stinger?
One is labelled "RN" the other just "R"

Which is upper and which is lower?

Cheers
Ash

OK well I sorted this one myself.. :lol:

The manual said that the top ring was a keystone type.
I used some whiteboard marker on each ring then rubbed on a flat surface, the "RN" ring was keystone. Sorted!
