The Heckler & Koch HK91A2 is a semiautomatic German-made battle rifle, a variant of the Heckler & Koch G3 produced between 1964 and 1976. This variant was designed for civilian use, and between 1974 and 1989, around forty-eight thousand were imported to the United States. To comply with American firearms laws, it has several modifications which make it incapable of fully-automatic fire.
