Cold War and Modern Weapons
By the end of World War II, all the essential types of small arms had been established, from handguns to machine guns. In the post-war world, however, there were two main revolutions. First was the rise and standardization of the assault rifle in weapons such as the Soviet AK-47 and the U.S. M16. Second came a transformation in materials and formats, which has led to ‘modular’ weapons capable of shifting between roles through quick adjustments in configuration. Through such changes, the battlefield soldier has never been better armed for combat.
AK-47/AKM (1949)
The AK series of assault rifles have quite literally transformed the world’s security situation. With more than 100 million of the family (including all variants) produced, the AK is the most mass-produced weapon in history.
The AK-47 was a fundamental step forward in Soviet firearms design. During World War II, the principal Soviet weapons had been the bolt-action Mosin-Nagant rifle and the full-auto PPSh-41 and PPS 43 SMGs. Yet as far back as the late 1930s, the Soviets experimented with what are known as ‘intermediate’ cartridges, positioned between the power of a rifle round and an SMG’s pistol round. What such a cartridge delivered was a combat range of about 400m (1312ft), but with a recoil impulse that could be managed on full-auto. Design such a cartridge, and the weapon to fire it, and you could virtually do away with conventional rifles and SMGs in favour of a single weapon for every soldier.
The AKM assault rifle can be distinguished from the earlier AK-47 by, among other things, a polymer pistol grip, angular muzzle brake and the more slender front sight block.
The Germans proved this concept during the war with their MP 44/StG 44 ‘assault rifle’, which fired a 7.92 x 33mm kurz (short) cartridge. In 1943, the Soviets responded by producing a 7.62 x 39mm round and chambered it for a semi-auto carbine, the SKS.
However, in 1944 Russian engineer Mikhail Kalashnikov, supported by a design team, began a competitive development against several other weapon producers to create a new selective-fire rifle that would use the intermediate round. It was a long process, and it should be noted that Kalashnikov himself was not the only key individual behind the final design. Another central figure was Aleksandr Zaitsev, who convinced Kalashnikov of the need for a major redesign to enhance reliability. Yet with the war over, in 1948 their ‘AK-47’ entered army trials and the following year it was adopted as the standard Soviet rifle.

In 1959, it was modernized – i.e. cheapened – in terms of its production methods, the receiver being of a stamped design rather than machined steel. Other improvements of the AKM, as it was known, included a basic scoop-like muzzle brake, a Parkerized bolt and a wire-cutting bayonet device. The AKM became the defining, most widely distributed model in the AK series.
The Chinese Type 56 is a near-identical copy of the AK rifle, manufactured from 1956 and still in service with Chinese forces today. An estimated 15 million have been produced.
Mythology
Much mythology has accrued around the AK, mainly on account of Hollywood representations. If you dig deeper, however, you find that it is no more powerful than many other assault rifles and it is not particularly accurate. What it does deliver, and in spades, is awesome reliability, total ease of use and maintenance, and vast distribution across the world.
In basic layout, the AK is a gas-operated weapon feeding from a 30-round detachable, instantly recognizable box magazine. It is selective fire – the large lever on the right of the receiver is the selector switch, which also adds to safety by preventing the bolt being cocked when the switch is in its uppermost position. The gas cylinder sits above the barrel, and houses a long-stroke gas piston that operates the bolt via a bolt carrier. The bolt itself is of the rotating type, and features two large locking lugs that, prior to firing, lock into recesses in the barrel extension. Rotating is performed via a cam track in the bolt carrier.
What this somewhat dry description does not evoke is the fantastic resilience of the AK mechanism. The long-stroke piston and the rotating bolt cope with all manner of dirt and contamination. The author has personally spoken to soldiers who have unearthed an AK after six months buried in the mud at the bottom of an African river, and fired straight through a magazine on full-auto without even cleaning the gun. (The AK barrels are also chromium-lined, and therefore incredibly resilient.) The furniture is similarly tough, whether the variant is fitted with a solid wooden stock or one of the folding metal types. Keep it clean and the AK will last a lifetime.
AKs are also extremely simple to use. To fire the weapon, just hinge a magazine into place, drop the selector level to either semi- or full-auto mode, cock and release the cocking handle and pull the trigger.

Global Presence
Such is the success of the AK design that it has spawned literally dozens of variants or copies (licenced and unauthorized), including SMGs, sniper rifles and even automatic shotguns. Short versions – given the AKS prefix – also served with Soviet Special Forces and continue to be popular today in insurgent hands. A major shift in the series occurred in the 1970s, however, when the Soviets rechambered the AK for the new 5.45 x 39mm M74 cartridge, in imitiation of the type of round used in the U.S. M16 rifle. The AK-74 carried the Soviet and Russian Federation through to the present day, and a truly convincing replacement has yet to be found. (See AK-74 and AK-12 entries.)

AK in Action
The extent of the AK series distribution cannot be understated, aided not least by lax post-Cold War sales restrictions. More than 30 countries have officially adopted or used the AK rifles for their armies, serving in every part of the world. If we add illegal use, or employment by insurgent armies, then there is scarcely a country in the world that has not in some way been touched by the AK – it is estimated that more than a quarter of a million people are killed by AKs every year.
Stripping the AK
Stripping down the AK for cleaning is as simple as handling it in action. The first step is to remove the magazine by pressing the magazine release catch forward, then depressing the latch (actually the end of the return spring guide) on the top rear of the receiver. This step allows you to remove the AK’s receiver cover, exposing the recoil spring and bolt mechanism. To remove these for cleaning, push the return spring forward so that it clears the housing, then lift it...
