In the late 1970s, H&K partnered with Hensoldt to create the ZP/AP (Ziel/Aiming; Projektor/Projector) and then ZPP/APP (Ziel/Aiming; Punkt/Point; Projektor/Projector). This was essentially a calibrated flashlight with an aiming point and pressure switch. It projected a beam of light that was specifically 2m wide at 50m distance, with a black spot in the center which would measure 30cm at 50m. This could be focused and zeroed o the black spot was a functional aiming point, allowing both target identification and engagement. The unit was attached to an H&K claw mount, and would fit any of the standard H&K small arms. Few of the items were imported into the US, as they were bulky, heavy (1.6kg / 2.6 lb) and expensive.
