ABSTRACT:
A power change mechanism for variable power riflescopes includes a resilient member disposed between the riflescope housing and the power change ring for automatically rotating the power change ring from one power setting to another upon activation of a latch mechanism. The automatic power change mechanism may include apparatus for overriding such automatic capabilities in order to provide for manual power change.
