The AK-47 was designed to be a simple, reliable fully automatic rifle that could be manufactured quickly and cheaply, using mass production methods that were state of the art in the Soviet Union during the late 1940s. [41] The AK-47 uses a long-stroke gas system generally associated with high reliability in adverse conditions.
Case-hardening or carburization is the process of introducing carbon to the surface of a low-carbon iron, or more commonly a low-carbon steel object, in order to harden the surface. Iron which has a carbon content greater than ~0.02% is known as steel .
The 7.62×39mm (also called 7.62 Soviet, formerly .30 Russian Short) [5] round is a rimless bottlenecked intermediate cartridge of Soviet origin. The cartridge is widely used due to the global proliferation of the AK-47 rifle and related Kalashnikov-pattern rifles, the SKS semi-automatic rifle, and the RPD/RPK light machine guns.
Color case hardening is the predecessor of all metal coloring typically employed in the firearms industry. Contemporary heat-treatable steels did not exist or were in their infancy. Soft, low-carbon steel was used, but strong materials were needed for the receivers of firearms. Initially case hardening was used but did not offer any aesthetics.
The 5.45×39mm cartridge is a rimless bottlenecked intermediate cartridge.It was introduced into service in 1974 by the Soviet Union for use with the new AK-74.The 5.45×39mm gradually supplemented and then largely replaced the 7.62×39mm cartridge in Soviet and Warsaw Pact service as the primary military service rifle cartridge.
The barrel on the Type 56 is similar to the AK-47 and heavier than that of the AKM though is pinned in like the AKM and unlike the AK-47. Military issued versions of the Type 56 also lack the threaded muzzle found on the AK-47 and AKM, this means they cannot use an AKM compensator or blank-firing device .
The Karabinek-granatnik wzór 1960 (Polish: Carbine-grenade launcher model 1960), also designated PMK-DGN-60 [1] or PMK-60, [2] is a Polish-made version of the AK-47 assault rifle that can fire rifle grenades.
This ammunition is unique among submachine guns in that the bullet is made almost entirely of a hardened steel penetrator instead of softer copper or lead. The MP7 has a cyclic rate of fire of around 950 rounds per minute [ 5 ] (which is around 15.8 rounds per second).
