  • The rare HK GR3 with a scope whether you want it or not

    Jonathan explores H&K's strange decision to plonk a low-power optic on a HK33, removing the excellent H&K iron sites in the mid-1980s.

    This specific weapon is shrouded in a host of strange quirks, as our Keeper of Firearms and Artillery explains.

  • Heckler & Koch HK33

    In this episode we take a look at Heckler & Koch's first 5.56x45mm rifle, the HK33. Introduced in the late 1960s, the HK33 was Heckler & Koch's response to the emergence of the new 5.56x45mm round and FN's introduction of the FN CAL. While the HK33 wasn't adopted by West Germany it proved a popul...

  • Heckler & Koch G41

    Following NATOs standardisation of 5.56x45mm, Heckler & Koch introduced the G41 in 1981, as NATO members began looking for new rifles. HK, however, struggled to find buyers for the G41. In this episode Matt takes a look at one of HK's rarest rifles. Comparing it to its predecessor the HK33 and di...

The 'Special Case' offered the firepower of an MP5K in a co...

  • HK 41: "Paramilitary Rifle" for the Bundeswehr

    The HK41 (designation: โ€œparamilitary rifleโ€, caliber 7.62x51mm) was the first semiautomatic version of the G3 military rifle. It was made for the Bundeswehr reservist market; a rifle that could be privately owned in Germany but which would duplicate the handling of the G3 for reservists to practi...

  • H&K's New SP5 - A Civilian Semiauto MP5 Pistol

    The MP5 is widely regarded as the best submachine gun ever made, and it has been widely copied. But only now has H&K released a semiauto civilian version of it in pistol form. Prior to the AWB, the HK94 was available as a semiauto carbine (with a 16" barrel), but that was prohibited in 1988. H&K ...

  • H&K's Experimental SMG and SMG II for the US Navy

    In the 1980s, the US Navy requested a new submachine gun to replace the MP5 then in use. In particular, the Navy wanted a gun that was optimized for use with a suppressor. H&K built two models of experimental guns in the 1980s to meet this request, creatively named the SMG and SMG II.

    Both gun...

  • H&K's Middle Child: The HK33 and HK53 in 5.56mm

    Introduced in 1968, the HK33 was Heckler & Koch's adaptation of their roller-delay operating system to the 5.56mm / .223 Remington cartridge. In addition to the standard full-length rifle (with a 15.35 inch barrel) a shorter version was made as the HK33K (with a collapsing stock and 12.4 inch bar...

  • HK-32 Prototype in 7.62x39mm

    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 ...

  • HK51: The SAS' Full Auto Flashbang Dispenser

    The HK51 is not a gun that was ever actually produced by Heckler & Koch. It is instead a variation on the G3/HK91 originally developed by American H&K specialist Bill Fleming. He was contracted by a UK-based company called FR Ordnance to produce a submachine gun sized version of the G3 for Britis...

  • Heckler & Koch's Modular Machine Gun: the HK21E

    In 1961, Heckler & Koch introduced a new light machine gun based on their roller-delayed blowback system as a companion piece to the G3/HK91 rifle. While the German military was quite happy with its MG3 machine guns, H&K expected that other, smaller nations adopting the G3 would be interested in ...
