Which statement is true about the M4 rifle?

• A. It is a 5.56mm, magazine-fed, gas-operated rifle with semi-automatic or three-round burst operation.
• B. It is a 7.62mm, bolt-action rifle.
• C. It is a 9mm pistol.
• D. It is a lever-action rifle.

Answer: (A)

The M4 is a 5.56mm, magazine-fed, gas-operated rifle with semi-automatic or three-round burst operation. This combination describes a compact carbine that fires small, high-velocity NATO ammunition, uses detachable magazines for quick reloading, and cycles the action automatically using gas from each shot. The selectable-fire option allows shooting either semi-automatic or a limited three-round burst, which has been a standard feature on many configurations. The other options describe a different weapon entirely: a larger-caliber 7.62mm bolt-action rifle, a 9mm pistol, or a lever-action rifle, none of which match the M4’s modern, gas-operated, magazine-fed design and its select-fire capability.
