I recently bought, secondhand and locally, the above combo. This is an experiment prior to possibly buying an MM4, to see if I can 'switch' to a smaller scope for general use. Firstly, I am very impressed with the IS 60R...it is marketed as a starter/budget scope, but it is no slouch, and outperforms my other 'lightweights'. Anyway...my question: on the Opticron website, it says the 40931 ep gives 25x, and needs an adapter. But it doesn't need an adapter, as far as I can tell. The 40931 screws directly into the IS 60 R body (which has three different sets of threads for different eps). Am I missing something?
