41 CARRYING SLING Carrying sling The carrying sling enables the UMP to be carried in several ways. In this process, the buttstock may be folded up or unfolded. The carrying sling is attached to the mounting points on the receiver, handstop, or buttstock via the carbine hooks. Length Adjustment • Close coupler • Rest the carrying sling between thumb and index finger and let the UMP hang down in a horizontal position. Adjust the length in such a way that there is a space of approximately 10 cm (4 inches) between your forearm and the UMP (Fig. 34). For adjustment • Slide the forward buckle and coupler with the sewn-up end as far as possible up to the front carbine. • Somewhat loosen the belt loop in the rear buckle. • To shorten the carrying sling, pull the upper loop forwards • To lengthen the carrying sling, pull the upper loop to the rear. • Tighten loop in the buckle • Tighten carrying sling Routing the Carrying sling In order to carry the UMP laterally against the body or in front of the body (ready position), or on the back, the carrying sling must be properly routed. To do so: • Pull the two halves of the carrying sling apart and upwards. • Place the upper part of the carrying sling onto your shoulder over your head.

45 SIGHT ALIGNMENT FOR THE UMP Sight Adjustment If the point of impact has to be corrected, this will be done by adjustment of the rear sight using the Allen wrench provided with the weapon. The UMP is zeroed at the factory to hit the point of aim at 25 meters (27.3 yards). Elevation adjustment • To lower the weapon’s point of impact, turn the elevation adjustment screw clockwise. • To raise the weapon’s point of impact, turn the elevation adjustment screw counterclockwise. NOTE: 1 revolution of the elevation adjustment screw changes the point of impact by 4.5 centimeters (1.77 inches) at a range of 25 meters (27.3 yards). Windage adjustment • To move the weapon’s point of impact to the left, turn the windage adjustment screw counterclockwise. • To move the weapon’s point of impact to the right, turn the windage adjustment screw clockwise. NOTE: 1 click of the windage adjustment screw changes the point of impact by 1.15 centimeters (.45 inches) at a range of 25 meters (27.3 yards).
