Which weapon uses a 7.62x51MM cartridge?

• A. Glock 17
• B. M16
• C. AK-47
• D. M240B

Answer: (D)

Understanding cartridge compatibility helps you see why this is the M240B. The 7.62x51mm NATO is a larger, heavier cartridge used by certain support and general-purpose machine guns for sustained fire. It’s longer and more powerful than smaller rifle rounds, which is why it’s chosen for weapons designed to deliver sustained, automatic fire. Glock 17 fires 9x19mm, not 7.62x51mm. The M16 uses 5.56x45mm, a smaller rifle cartridge. The AK-47 typically uses 7.62x39mm, which is a different designation and caliber than 7.62x51mm. The M240B, however, is a belt-fed machine gun designed to chamber 7.62x51mm NATO, matching the cartridge in question and enabling sustained fire. So, the weapon that uses the 7.62x51MM cartridge is the M240B.
