The AKU-94 is a bullpup conversion kit (built and originally sold as a kit by K-VAR) for the AK type rifle, Both the European style AKs (like the Romanian AKs or Egyptian Maadis) and the Chinese style of AK rifle (Type 56) can fit into the kit. In the Mid-2000s, KVAR stopped making and selling the AKU-94 conversion kit. All remaining kits were purchased by Century Arms International, and subsequently used to 'spruce up' AK rifles with a futuristic bullpup look. Currently various imported AK rifles (mostly WASRs) with kit installed, is sold by Century Arms International. This bullpup configuration retains the standard barrel length but the design makes the AK rifle more compact making it more suitable for close quarters battle.
Both licensed and unlicensed production of the Kalashnikov weapons abroad were almost exclusively of the AKM variant, partially due to the much easier production of the stamped receiver. This model is the most commonly encountered, having been produced in much greater quantities. All rifles based on the Kalashnikov design are frequently referred to as AK-47s in the West, although this is only correct when applied to rifles based on the original three receiver types.  In most former Eastern Bloc countries, the weapon is known simply as the "Kalashnikov" or "AK". The differences between the milled and stamped receivers includes the use of rivets rather than welds on the stamped receiver, as well as the placement of a small dimple above the magazine well for stabilization of the magazine.
