As of today, HK-91 clones are available, such as the PTR-91 (Formerly JLD), which are built on the tooling used by arms-maker FMP to make the receivers of the Portuguese military's versions of the G3, the M/961 and M/963. Heckler & Koch's receiver tooling was sold to the American company Ohio Rapid Fire, which was in the process of setting up to produce receivers until the passing of the company owner, Todd Grove. Ohio Rapid Fire has since closed its doors in 2010.
