What is the weight of the M4 Carbine?

• A. 6.9 lbs
• B. 7.2 lbs
• C. 6.2 lbs
• D. 7.0 lbs

Answer: (A)

The amount being tested is the rifle in its standard field configuration—the M4 Carbine with a loaded magazine. In that typical setup, soldiers carry about seven pounds of weapon weight. Training and field manuals commonly list a figure around 6.9 pounds for a loaded M4, which fits the standard loadout of the rifle with a 30‑round magazine and no extra heavy accessories.

Weights can shift a bit if you add optics, vertical grips, suppressors, or other gear, but for the common, ready-to-fire configuration, 6.9 pounds is the most representative figure. The other options would place the weapon outside the usual range for a standard load, either lighter than a fully loaded configuration or heavier than what's typically issued.
