Abstract
The present invention provides an erector system characterized by centered erector lenses and lens holder movement capability to alter relative erector lens placement. Alignment of the erector lens optical centers facilitates the reduction of the phenomenon of trackout. Alteration of relative erector lens position permits a pistol scope or another device embodying the erector system to operate at more than one magnification.
