The felt recoil is therefore eliminated, enhancing accuracy and assisting control during fully automatic fire. The travel distance of the AK-107 reciprocating parts is less than other Kalashnikov designs, so the cyclic rate is higher at 850–900 rounds/min rather than 600 rounds/min on other AK rifles. However, as the felt recoil is virtually ...
The PBS-1 silencer, designed for use with the AKM to reduce the noise when firing, was introduced in the 1960s, and was used mostly by Spetsnaz forces and the KGB. [3] [4] [5] They were used by the Spetsnaz in the Soviet–Afghan War in the 1980s, requiring the use of the AKM (modernized variant of the AK-47), because the newer AK-74 did not have a silencer available.

The AKM is an automatic rifle chambered in 7.62×39mm intermediate cartridge. It is a selective fire, gas operated with a rotating bolt, firing in either semi-automatic or fully automatic, and has a cyclic rate of fire of around 600 rounds per minute (RPM).
Recoil is reduced by 50% and the design allows the user to fire the rifle, unload and load the magazine with one hand. [8] The Malyuk can either retain the AKM-based selective fire or an ambidextrous low-profile two-position selector for semi and full auto fire. [9]
Tests measured the free recoil energy delivered by the 5.45×39mm AK-74 rifle at 3.39 J (2.50 ft⋅lb), compared with 7.19 J (5.30 ft⋅lb) delivered by the 7.62×39mm in the AKM. [ 35 ] Early 5.45×39mm ballistics tests demonstrated a pronounced tumbling effect with high speed cameras. [ 36 ]
Later Kalashnikov started offering the AK-107 / AK-108 / AK-109 (in order 5.45x39, 5.56x45, 7.62x39) models. Externally they are very similar to the AK-100 series (with some minor differences) and are offered in the same calibers.
The Bizon uses a simple straight blowback method of operation; an unlocked breech system reduces cost and build complexity. [3] The Bizon's operating cycle is characterized by a very short recoil stroke; standard 9×18mm ammunition will only drive the bolt partially to the rear of the receiver and results in a cyclic rate of 680 rounds per ...
Its firepower, ease of use, low production costs, and reliability were perfectly suited for the Soviet Army's new mobile warfare doctrines. More AK-type weapons have been produced than all other assault rifles combined. [34] In 1974, the Soviets began replacing their AK-47 and AKM rifles with a newer design, the AK-74, which uses 5.45×39mm ...
