What is the AK-47/AKM cartridge type?

• A. 5.56x45mm
• B. 7.62x39mm
• C. 7.62x54R
• D. 9x19mm

Answer: (B)

The AK-47/AKM was designed around an intermediate rifle cartridge that balances recoil, controllability, and reliability for automatic fire. The cartridge used is 7.62x39mm, meaning a 7.62 mm bullet housed in a 39 mm case. This size provides enough energy for effective engagement at typical combat ranges while keeping recoil manageable and ensuring smooth, reliable feeding in the AK’s gas-operated, rotating-bolt action. In practice, that combination became the defining fit for the platform, enabling reliable operation even in harsh conditions. Comparatively, 5.56x45mm is the smaller, higher-velocity round associated with the M16 family; 7.62x54R is a longer, more powerful full-power rifle round used in older Mosin-Nagant rifles and some machine guns; and 9x19mm is a pistol/submachine gun cartridge. Each of those serves different weapons and roles, so they don’t match the AK-47/AKM’s design and operating principles.
