The AK-47 has earned a legendary status as one of the most reliable and widely used assault rifles ever produced. With over 100 million units manufactured globally, it remains the most distributed firearm in the world. Designed by Russian inventor and soldier Mikhail Timofeevich Kalashnikov (1919–2013), the AK-47 became a symbol of military power and guerrilla warfare across the globe.
Introduction to the AK-47
The AK-47’s influence spans decades and continents. Numerous Kalashnikov models, clones, and derivatives have been developed worldwide. Despite variations in design and configuration, the rifle’s core functionality remains largely unchanged—durable, simple, and lethal.
Design and Development
Originally, created to replace the SKS rifle and serve Soviet tank crews, the Avtomat Kalashnikova 1947 (AK-47) began development in 1946 at the Kovrov weapons plant. In 1949, the rifle was officially adopted as the standard infantry weapon of the Soviet Army and retained that role until the introduction of the AKM.
Key Specifications of the AK-47
The original AK-47 featured hardwood furniture, a fixed wooden stock, and a muzzle nut to protect barrel threads. Although it initially lacked a bayonet lug, this feature was added in later versions. The buttstock also includes a hollow compartment for a cleaning kit.

Modernization and Evolution of the AK Series
Initial Adoption and Early Variants (1947–1959)
The first-generation AK-47 entered service in 1947 and continued production until 1959. Over time, many countries produced licensed or unlicensed variants, often making minor design modifications.
In 1959, the AKM (a modernized version) was introduced. This updated model used lighter stamped parts, reducing production costs and improving reliability.
Development of RPK and PK Series
Simultaneously, light and heavy machine guns based on the AK platform were developed:
- RPK-47: A squad automatic weapon with a fixed or folding stock.
- PKS: Heavy machine gun.
- PKB: Vehicle-mounted machine gun for armored carriers.
- PKT: Tank-mounted version.
Introduction of Small-Caliber Variants (AK-74 Series)
In the late 1960s and early 1970s, the Soviet Union began developing weapons for small-caliber cartridges to improve accuracy, control, and battlefield effectiveness.
After extensive testing, the 5.45×39mm cartridge with a steel-core bullet was adopted. This led to the creation of the AK-74, which entered service in 1974.
AK-74M Modernization
In 1990, the AK-74M was introduced with the following enhancements:
- Folding polymer stock
- Integrated optics mounting rail
- Improved durability and modularity
By 1991, the RPK-74M light machine gun also entered service, replacing multiple older variants.
The AK-100 Series and International Expansion
To expand global reach and adapt to NATO standards, Kalashnikov Concern (formerly Izhmash) developed the AK-100 series in the 1990s:
| Model | Caliber | Features |
|---|---|---|
| AK-101 | 5.56×45mm NATO | Full-length barrel |
| AK-102 | 5.56×45mm NATO | Short barrel |
| AK-103 | 7.62×39mm | Full-length barrel |
| AK-104 | 7.62×39mm | Short barrel |
| AK-105 | 5.45×39mm | Short barrel |
These models were intended for both domestic use and international export.
Civilian Use: The Saiga Series
In 1993, under the defense industry’s initiative, the Saiga line of self-loading carbines was developed. Designed for civilian hunting and sport shooting, these rifles retained the AK’s legendary reliability while complying with civilian firearm regulations.
Why the AK-74 Isn’t as Popular as the AK-47
Despite technological improvements, the AK-74 never achieved the global iconic status of the AK-47. The reasons include:
- Limited ammunition availability outside of former Soviet states.
- Cultural and historical impact of the AK-47 during Cold War conflicts.
- Global surplus of AK-47s making them more accessible and affordable.

Conclusion
The AK-47 remains a symbol of simplicity, ruggedness, and global impact. With over 100 million units produced, it is more than just a rifle—it is a piece of military history. While newer models like the AK-74 and AK-100 series offer advanced features and improved ergonomics, the original AK-47 continues to serve in conflicts worldwide and stands as a testament to Mikhail Kalashnikov’s enduring legacy.
