ABSTRACT:
A method and apparatus relate to an optical sight having a first section, and having a second section that is movable relative to the first section, and that has optics thereon. One aspect involves: preventing movement of the second section away from a first position past a second position; responding to movement of a member relative to the first section from a third position to a fourth position by moving the second section from the first position to the second position; resiliently urging the second section away from the first position and past the second position when the member is on a side of the fourth position remote from the third position; and releasably retaining the member in a position on a side of the fourth position remote from the third position.
