How does the AK-47 work?

Edition Tiago Jokura and Felipe van Deursen

In a simple and ingenious way, developed for years by the Russian Mikhail Kalashnikov in the 40s. Very cheap and resistant to cold, heat, water and sand, the rifle became the most widespread weapon in the world, with 80 to 100 million units scattered in conflicts on all continents. He ended up becoming a sinister icon of the 20th century. Samuel L. Jackson idolizes him in Quentin Tarantino’s Jackie Brown. Former Iraqi dictator Saddam Hussein was with two of them when he was arrested in 2003. Years earlier, he ordered the construction of a mosque with four minarets in the shape of Tabuk, Iraq’s version of the AK. Photos and videos of Osama bin Laden showed him holding the rifle, recognizable by the shape of the clip.

straight and straight

The Avtomat Kalashnikova was released in 1947 – hence the name AK-47

1. There are three firing modes: locked, semiautomatic (one shot at a time) and automatic (600 shots per minute). Just use this lever above the trigger

2. When the weapon is loaded, the rotating bolt advances, pushing the cartridge as it rotates on its own axis. This facilitates the entry movement of the cartridge, which is positioned in the breech

3. When pressing the trigger, the hammer of the gun hits the precursor, which explodes the explosive of the cartridge. The generated gases expel the bullet through the barrel at over 2,500 km/h

4. While the bullet travels through the barrel, the gases from the gunpowder explosion have nowhere to escape (since the cartridge covers one end and the projectile the other). When the bullet is about to exit, an opening directs part of the gases into a parallel tube.

5. The gases press on a plunger, which pushes on a rod and moves the bolt holder backwards. The bolt recoils, cocks the hammer for the next shot, and opens the breech, which spits out the spent shell. This frees up space for a new round to enter the chamber, thanks to the magazine spring, which pushes the ammunition up.

6. The movement of the bolt is stopped by a spring that returns it to the initial position and pushes the new cartridge towards the breech

The secret of success

Four innovations that consecrated the rifle

More space

Guns of this type tend to jam when snow, mud, or water is involved. The AK-47 suffers less from this problem because it has more space between parts. In addition, dirt does not accumulate. It is expelled in the firing process

turn screw

The common bolt pushes the cartridge into the breech. The AK uses a rotary bolt, which, in addition to normal movement, rotates on its axis. This helps the cartridge entry and lessens the chances of jamming.

lighter ammo

While the rifles of its time used heavy ammunition, the AK bet on an intermediate one, with a quieter recoil. This democratized its use, as the less experienced could handle the impact without losing accuracy.

banana shape

The famous curved comb has a reason for being. The bullets are thinnest at the tip, so when stacking the shells on top of each other, they naturally clump together in the iconic banana shape.

1947

LAUNCH

Russian Mikhail Kalashnikov, veteran of World War II, gets approval for the large-scale manufacture of his rifle, which took years of development work. Inspired by the pioneering MP40, the AK-47 undergoes around 100 modifications until 1949

1956-1964

SOCIALIST ICON

In the context of the Cold War, the Soviet Union authorized other socialist countries to manufacture the rifle. Thus, Bulgaria, East Germany, Hungary, China and Poland start to produce the AK

1955-1975

VIETNAM WAR

With the entry of the United States into the Vietnam War, for the first time the AK, used by North Vietnam, was face to face with the North American M-16, its main adversary. The US gun took a stick, as it stuck with moisture and dirt. On the other hand, AKs that were buried for years after the war worked (and well) when they were dug up.

1974

INNOVATION

A new version appears, the AK-74, with a third less recoil than the AK-47. The handle and stock, before made of wood, are now made of polymer, which made it lighter (3.4 kg). Bullets get smaller (5.45 x 39 mm) but become more lethal, fragmenting inside the body

1979-1989

AFGHANISTAN WAR

For the first time the AK is used against the Soviets. In the midst of the Cold War, the mujahedin (“holy warriors”) of Afghanistan sought US assistance. Frightened by the high destructive power of the AK-74, they claim the same weapons from the US government, which starts to buy them, mainly in China.

1989

ARMS MARKET

Thousands of AKs fuel the civil war raging in Afghanistan. In the following years, the rifle spread to neighboring countries, creating weapons routes that last until today. At that time, it was possible to buy handcrafted versions in Middle Eastern countries. The Soviet model cost an average of US$ 1,400, the Chinese US$ 1,150 and the handmade, much cheaper, US$ 400

late 90’s

AFRICA IN FURY

Due to the low cost and high reliability, AK is widespread in Africa. It is estimated that from 1990 to the 2000s, the continent has faced more than 100 armed conflicts. Back then, an AK could be bought for a measly $10

1993

PEACE IN MOZAMBIQUE

After the end of the civil war, there are between 5 and 10 million guns in the country, mostly AKs. Its cultural impact is so great that it goes on the Mozambican flag (in addition, it is on the coat of arms of Zimbabwe)

early 90’s

WAR ON DRUG

International traffic is growing dramatically. The arsenal left over from the end of the civil wars of independence in Central America and the collapse of the USSR shifts to guerrilla groups and drug cartels in Latin America. groups located in the humid Amazon rainforest

2005

VENEZUELAN PACKAGE

Hugo Chávez, President of Venezuela, orders 100,000 AKs. Years before, the Revolutionary Armed Forces of Colombia (FARC) had purchased models with refueling problems in Latin America. Because of this, Chávez is accused of wanting to arm the FARC
