Among the large family of roller-delayed rifles produced by Heckler & Koch, one of the rarest and least known is the HK32. This was the select-fire shoulder rifle chambered in 7.62x39mm. These rifles appeared in H&K sales literature for a time, but were only made in very small numbers for one or two poor documented contracts. What we have here today is a very early prototype rifle in 7.62x39mm using a regular NATO caliber receiver with a magazine well block to fit a proprietary H&K magazine. The rifle retains many CETME features, including the muzzle brake, metal forehand with integral bipod, carry handle, stock design, and a unique 2-position rear notch sight.
Many thanks to the Royal Armouries for allowing me to film and disassemble this very rare rifle! The NFC collection there – perhaps the best military small arms collection in Western Europe – is available by appointment to researchers. Anyone, however, can browse the various Armouries collections online here.
