Precision rear diopter sights with iris aperture systems, color filters, and mounting accessories for 10-meter air rifle and three-position competition. Sport Shooting Depot's rear sight selection is anchored by Gehmann's full lineup — from the entry-level iris-only Model 530 through the multi-color filter units like the Model 566 and 569, up to the combined diopter-plus-filter Model 570. Gehmann iris systems allow fine aperture adjustment from 0.5mm to 3.0mm and are widely used at national and international competition levels. For shooters who want to run their diopter and filter as a combined unit, the 570 series eliminates the stack height of running two separate pieces. MEC's Track Max Speed raiser block and Block Max vertical adjuster provide precise elevation tuning independent of the sight's internal adjustment. ahg-Anschütz raiser blocks offer a cost-effective height solution compatible with most standard rear sight rails.
