The AK-47 in 5.56 NATO: A Myth Debunked
The idea of an AK-47 chambered in 5.56x45mm NATO is a persistent myth among firearms enthusiasts. While the AK platform is incredibly versatile and has seen countless variations, a true, factory-produced AK-47 chambered in 5.56 NATO simply doesn't exist. This article will delve into why this is the case, exploring the design differences between the 7.62x39mm round and the 5.56x45mm, and examining the challenges and implications of such a conversion.
Understanding the Core Differences: 7.62x39mm vs. 5.56x45mm
The fundamental reason behind the lack of a genuine 5.56 AK-47 lies in the significant differences between the original 7.62x39mm cartridge and the 5.56x45mm NATO round. These differences extend beyond mere caliber:
-
Case Size and Shape: The 7.62x39mm cartridge boasts a larger, more robust case. The 5.56x45mm, on the other hand, is considerably smaller and uses a bottlenecked case. Simply swapping cartridges would necessitate major modifications to the receiver and bolt mechanism of the AK-47.
-
Pressure and Dimensions: The 5.56x45mm operates at higher pressures than the 7.62x39mm. Adapting the AK-47's action to handle this increased pressure safely requires significant engineering and metallurgical adjustments, far beyond a simple barrel change.
-
Bolt Design: The AK-47's tilting bolt mechanism is optimized for the 7.62x39mm. To reliably handle the 5.56x45mm, changes to the bolt face, locking lugs, and potentially the entire bolt carrier group would be essential.
The Reality of "5.56 AKs": Conversions and Variations
While a true factory-produced AK-47 in 5.56 NATO is nonexistent, various manufacturers offer AK-pattern rifles chambered in 5.56x45mm. However, it's crucial to understand these are not conversions of original AK-47s. Instead, they are:
-
AK-pattern rifles: These utilize the iconic AK design elements, such as the gas-operated mechanism and stamped receiver, but are built from the ground up for the 5.56x45mm cartridge. They are fundamentally different from the original AK-47. Examples include the various AR-15 inspired AK-pattern builds.
-
Custom Conversions: While possible, converting an original AK-47 to 5.56x45mm is a complex and potentially dangerous undertaking. Such conversions often require significant gunsmithing expertise and may compromise the rifle's reliability and safety. Improper conversions can lead to malfunctions, catastrophic failures, and injury.
Conclusion: Myth vs. Reality
The persistent myth of the 5.56 AK-47 stems from a desire to combine the legendary reliability of the AK platform with the versatility and widespread availability of the 5.56x45mm cartridge. While AK-pattern rifles chambered in 5.56x45mm exist, they are not conversions of the original AK-47 but entirely different designs. Attempting to convert an AK-47 to fire 5.56x45mm should only be attempted by highly experienced and qualified gunsmiths, with a full understanding of the significant risks involved. Always prioritize safety and responsible gun ownership.
