I recently bought a Nikko Diamond (10-50 x 60) secondhand which I am finding a great scope. It's a mark 1 I believe - the turrets are black, not green.
However, the elevation turret is very stiff; it is difficult to feel the clicks through it when adjusting.
Can anyone give an advice about how to make it EITHER easier to turn (can the turret mechanism be loosened/oiled?); OR is it possible to make the clicks more pronounced, so you know exactly how much you're winding on?
