And one scope type might satsfy your needs but it will not fit all occasions.

Duplexes are Ok for average use but give way to special reticles in dim light. German 4as are much more useful then and, hell, they even had posts and crosshairs in the bad old days. Illuminatred reticles -- Trijicon and others -- also have their place.

The scope makers who ignore the demand for fixed power and low light glass just concede that market to the few who have offerings --however imperfect.
