Some advise please

[justwannano]

I'm gonna put a scope on my mauser.
It will be mounted on the rear sight.
I think I'm looking for a long eye relief pistol scope but thats about all I know.

There sure seem to be a lot of red dots out there.Do I want one?

I wear glasses and have a touch of cataracts but the eye doctor said it is so minor he wouldn't even diagnose it.

So watdaya guys think?
