Ak-47 Technical Data Pdf ^NEW^ Download

During the Cold War, the Soviet Union and the People's Republic of China, as well as United States and other NATO nations supplied arms and technical knowledge to numerous countries and rebel forces around the world. During this time the Western countries used relatively expensive automatic rifles, such as the FN FAL, the HK G3, the M14, and the M16. In contrast, the Russians and Chinese used the AK-47; its low production cost and ease of manufacture allow them to make AKs in vast numbers.

The Kalashnikov assault rifle, also known to the West as the AK-47 (Avtomat Kalashnikova - 47, Kalashnikov automatic rifle, model of 1947), and its derivatives, also known under the common name of AK, is the most prolific small arm of the 2nd half of the XX century. It had been and still is (in more or less modified form) manufactured in dozens of countries, and used in hundreds of countries and conflicts since its introduction. The total number of the AK-type rifles made worldwide during the last 60 years is estimated at 90+ millions. This is a true legendary weapon, known for its extreme ruggedness, simplicity of operation and maintenance, and unsurpassed reliability even in worst conditions possible. It is used not only as a military weapon, but also as a platform for numerous sporting civilian rifles and shotguns (see Saiga semiautomatic shotguns, for example). The AK is an amalgam of previously known features and solutions, combined in the most effective way. The effectiveness, however, depends on the criteria used to measure it, and the key criteria for any and every Soviet and Russian military arm are: Reliability, Simplicity of operation and maintenance, Suitability for mass production. There never was any significant demand for good ergonomics or superb accuracy, though. The true story of AK began late in 1942, when Soviet troops captured several specimen of the very new German MKb.42(H)machine carbine (assault rifle), along with some 7.92 Kurz ammunition. By mid-1943 the MKb.42(H) along with US-supplied M1 carbine were evaluated by Soviet experts, and it was decided on top level that similar weapons, firing the intermediate power cartridge, must be developed for Soviet army as soon as possible. The task of initial development of new ammunition was accomplished in rather short time. By November 1943 technical specifications for the 7.62x41mm cartridge, having bottle-necked, rimless case and firing 8-gram pointed bullet, were sent out to all Soviet small arms design bureaus and organizations. By the spring of 1944, there were at least ten designs of automatic weapons in the works (not counting semi-automatic carbines that resulted in adoption of SKS and bolt-action carbines that went nowhere). In mid-1944, trials commission selected the AS-44 assault rifle, designed by Sudayev, as the overall best, and ordered a limited production run for troops trials. Some AS-44 rifles were manufactured in spring of 1945, and these were evaluated by troops in summer of 1945, just after the Victory in Europe. Troops generally liked the AS-44, as it has longer effective range compared to PPSh-41 submachine gun, and provided better accuracy in semi-automatic fire. The problem was that AS-44 was overly heavy (more than 5 kg empty), and trials commission ordered next round of development and trials, which started early in 1946.
American M1 Garand rifle. This carbine, while not successful by itself, served as a starting point for the first Kalashnikov's assault rifle, provisionally known as AK No.1 or AK-46. In November 1946 the AK-46 project was chosen for prototype manufacture along with 5 other projects (out of 16 submitted to commission), and Kalashnikov was sent to the city of Kovrov (also not far from the Moscow), to manufacture his weapon at the small arms factory there. The AK-46 was gas operated, rotary bolt weapon that utilized short-stroke gas piston above the barrel, and two-part receiver with separate trigger unit housing and dual controls (separate safety and fire selector switches on the left side of the trigger unit).In December 1946 new assault rifles were tested at NIPSMVO range, with AS-44 being used as a control (its development has ceased earlier in 1946 due to untimely death of the Sudayev, who was severely ill by the 1945). As an initial result of these tests, the AK-46 was selected for further development by trials commission, with two more weapons selected for further evolution being rifles from designers Dementiev and Bulkin. The second round of trials, which included three weapons (AK-46 by Kalashnikov, AB-46 by Bulkin and AD by Dementiev), resulted in rejection of the improved AK-46, which was inferior to other rivals in many aspects. Despite that failure, Kalashnikov, using his contacts and support from some member of trials commission (whom he knew from his earlier work at NIPSMVO in 1943-46) pursued the head of the trials commission to review the results, and finally got a green light to continue his development for next round of trials. Following the technical failure of the AK-46, Kalashnikov and his companion designer Zaitsev (who was a staff weapons designer at Kovrov plant) decided to completely rework the design, using successful technical solutions borrowed from various weapons, including direct competitors. For example, the long-stroke gas piston, attached to the bolt carrier, along with captive return spring assembly and receiver cover were apparent
This lead the Soviet army to issue new requirements for a lighter and more effective assault rifle, which were formulated in 1955. These requirements were also complemented by requirement for a companion squad automatic / light support weapon (light machine gun in Russian nomenclature). Trials for new weapons were held in 1957-58. Kalashnikov team from Izhevsk submitted an improved AK with new type of stamped receiver and other minor improvements, which competed against a number of weapons from other design teams from the Kovrov and Tula. In technical terms, the Kalashnikov entry fared about average in these trials, with certain rival weapons proving to be more combat-effective and less expensive to make. The trials commission, however, decided again that the better is the enemy of the good, and recommended the improved AK for adoption due to its proven performance and familiarity to the industry and troops. It was officially adopted in 1959 as the AKM ( Avtomat Kalashnikova Modernizirovannyj - Kalashnikov Automatic rifle, Modified) along with companion RPK squad automatic weapon / light machine gun.
The AK and AKM rifles were widely exported to the pro-Soviet countries and regimes all around the world. Manufacturing licenses along with all necessary technical data packages were transferred (for free or at nominal fee) to many Warsaw Pact countries (Albania, Bulgaria, China, East Germany, Hungary, North Korea, Poland, Romania, Yugoslavia). Certain 'non-communist', but friendly countries, such as Egypt, Finland and Iraq, also received manufacturing licenses.
