context_page_description: The HK33 is a 5.56mm assault rifle developed in the 1960s by West German armament manufacturer Heckler & Koch GmbH, primarily for export.
  Building on the success of their G3 design, the company developed a family of small arms consisting of four types of firearms: the first type, chambered in 7.62×51mm NATO; the second, using the Soviet 7.62×39mm M43 round; the third, chambered in the intermediate .223 Remington and 5.56×45mm NATO; and the fourth type, chambered for the 9×19mm Parabellum pistol cartridge. Commercially the HK33 was a successful design but it did not sell as well as the G3.
  The HK33 series of rifles were adopted by the Brazilian Air Force, the armed forces of Thailand and Malaysia where they were produced under a licence agreement. The rifle was also licence-built in Turkey by MKEK, and exported from France branded as MAS but actually made in Germany.

  Heckler &  Koch also manufactured a semi-automatic only variant of the HK33A2 for the civilian market called the Heckler & Koch HK43. The HK40-series was designed for sale to conscripts so they could be familiar with their service rifle before entering military service, a common practice in Germany and Switzerland. They had a bayonet mount and furniture just like the military model, but came with a semi-auto trigger pack instead of a full auto trigger pack. This allowed a civilian rifle to be easily made into an assault rifle just by dropping in a full auto trigger pack. It would be succeeded by the HK93A2 and its retractable stock version the HK93A3. The HK93 series had a redesigned semi-automatic trigger pack and metal shelf installed in the trigger group well that made it impossible for it to fit a full-auto trigger pack. It also had the bayonet mount removed and had different furniture.
  C-93
  Civilian semi-automatic sporting version produced by Century International Arms, Inc. It comes with an 18.9 or 16.25-inch (413 mm) barrel with a 1:9 twist ratio. A carrying handle and 40-round magazine are standard. Advertised weight is 8.2 lbs. The C-93 is built from Thai Type-11 parts kits using an American made barrel and other miscellaneous American parts.
