Licensed copies of the G3 and HK-91 were produced in Greece by Hellenic Arms Industry or "EBO", using factory tooling purchased from Heckler & Koch. A small number of these HK-91 clones, which are functionally and aesthetically identical to the German-made rifles, were imported into America by Springfield Armory, Inc. and sold under the designation SAR-8. These rifles, which ceased being imported in 1994, are not to be confused with later Springfield-made SAR-8 model rifles which feature cast aluminum receivers and are considered of markedly lower quality, being valued at far less than the original Greek models.
