Overview

In the mid to late 1960s, Heckler & Koch developed the HK33, which was a scaled-down version of the Heckler & Koch G3, but chambered for 5.56×45mm NATO. The HK33 entered production in 1968. In 1974, a semi-automatic version of the HK33 was introduced by H&K and was designated the HK43. According to H&K’s numbering nomenclature, the “4” indicates that the weapon is a paramilitary rifle, and the “3” indicates that the caliber is 5.56 mm.

A HK43 version KA1 with a shorter 322 mm barrel was used in 1977 by the German RAF terrorist group to assassinate general attorney Siegfried Buback and two policemen.[1] [2] Verena Becker, another former RAF member, has also claimed Wisniewski was the killer.[2]
