The AK-74 is an assault rifle designed by small arms designer Mikhail Kalashnikov in 1974 as a successor to the AKM. While primarily associated with the Soviet Union, it has been used by many countries since the 1970s. It is chambered for the 5.45×39mm cartridge, which replaced the 7.62×39mm cartridge of Kalashnikov's earlier automatic weapons for the Soviet Armed Forces.
A bullpup firearm is one with its firing grip located in front of the breech of the weapon, instead of behind it. This creates a weapon with a shorter overall length for a given barrel length, and one that is often lighter, more compact, concealable, and more maneuverable than a conventionally configured firearm. Where it is desirable for troops to be issued a more compact weapon, the use of a bullpup configuration allows for barrel length to be retained, thus preserving muzzle velocity, range, and ballistic effectiveness.
The AK-105 is a short barrel, carbine version of the AK-74M rifle, originally developed to replace the shorter barrelled AKS-74U. The AK-105 is chambered in 5.45×39mm ammunition and is used domestically by the Russian Army in contrast to other AK-100 series rifles.
The AS Val "Shaft" and VSS Vintorez "Thread Cutter", 6P30 and 6P29 respectively, were a Soviet-designed assault rifle featuring an integral suppressor based on the prototype RG-036 completed in 1981 by TsNIITochMash. The two rifles hereafter are referred to as the Vintorez and Val. The Vintorez and Val were developed by TsNIITochMash to replace modified general-purpose firearms, such as the AKS-74UB, BS-1, APB, and PB, for clandestine operations, much like the PSS Vul. Manufacturing began at the Tula Arms Plant after its adoption by the Armed Forces of the Soviet Union in 1987.

Heavily based on the AS Val, but lacking an integral suppressor, it has a newly designed folding stock and charging handle for ease of concealed carry. The abbreviation "SR" stands for spetsialnaya razrabotka—special development.
The AK-9 is a Russian 9×39mm compact rifle. Its development began when Izhevsk Machine-Building Plant (Izhmash), now known as Kalashnikov Concern started working on a new silent, flame-less, compact AK rifle in the early 2000s. When creating the new weapon, the manufacturers have tried to surpass all available competitors, such as the AS Val and SR-3M. The basis for the silent, flame-less shooting complex rifle was designated as the AK-9, where it uses a quick-detachable suppressor.

An assault rifle is a select fire rifle that uses an intermediate-rifle cartridge and a detachable magazine. Assault rifles were first put into mass production and accepted into widespread service during World War II. The first assault rifle to see major usage was the German StG 44, a development of the earlier Mkb 42. While immediately after World War II, NATO countries were equipped with battle rifles, the development of the M16 rifle during the Vietnam War prompted the adoption of assault rifles by the rest of NATO. By the end of the 20th century, assault rifles had become the standard weapon in most of the world's armies, replacing full-powered rifles and submachine guns in most roles. The two most successful modern assault rifles are the AK-47 and the M16 designs and their derivatives.

A new variant of the K-3 was unveiled to the public nearly a decade after its initial debut.
