Heckler & Koch HK32

The HK32 is a prototype assault rifle designed and manufactured by Heckler & Koch between the 1960s and late 1970s to further develop and modernize the HK G3 rifle. Few examples were made, and it never entered service before Germany adopted the G36 in the late 1990s.
Because of increasing demand for HK rifles to enter the US civilian market, modernized versions of the G3 rifle and variations are manufactured through the PTR series of weapons, which included a version of the HK32 known as the PTR-32.
