What is the weight of the M16A4 rifle?

• A. 8.79 lbs
• B. 7.50 lbs
• C. 9.25 lbs
• D. 8.00 lbs

Answer: (A)

The key point is knowing the standard published weight for the M16A4 with its common equipment. Official specifications list the M16A4 at about 8.79 pounds when equipped with a 30‑round magazine. That figure reflects the rifle’s metal receiver and barrel plus standard furniture and a loaded magazine, which is why it’s the figure you’ll see in manuals and training materials. The other numbers don’t match the published weight adopted for field reference, so 8.79 pounds is the correct reference value.
