The CZ 452-2E ZKM small bore rifle sights were sighted-in at the manufacturing plant at a 50 m distance. The tangent rear sight is provided with lines for 25 - 200 m aimed shooting in diversion steps of 25 m.
After depressing the rear sight-locking piece it is possible to shift the slide for the desired range. Windage adjustment is achieved after loosing the screw (Fig. 7) on the side you want to shift the point of impact and then tighten the screw on the opposite side. A full turn of the screw shifts the point of impact 5 cm (2 in.) at 50 m. Elevation correction is carried out by drifting the front sight in a dovetail. The front sight is secured in its place by a screw. The front side base is provided with auxiliary lines (Fig. 8). Drifting the front sight by one line shifts the point of impact by 1.5 cm (.6 in.) at 50 m.
On the CZ 452 ZKM Scout version, windage correction is carried out by shifting the front sight in the transverse groove, and securing it in the desired position with an indentation punch. Elevation adjustment is carried out by shifting of the rear sight leaf slide (Fig. 10). Shifting the slide by one increment changes the point of impact by 1.25 cm (.5 in.) at 50 m.
