What is the weight of the M-16A4 configured with a sling, a 30-round magazine, and a bayonet?

• A. 9.0 pounds
• B. 9.5 pounds
• C. 10.0 pounds
• D. 9.8 pounds

Answer: (B)

When you estimate the weight of the M16A4 with its standard extras, you add up the weight of each part that comes along: the rifle itself, the magazine, the bayonet, and the sling. The rifle in its basic form runs roughly in the mid‑7 pounds range. A loaded 30‑round magazine adds about a pound. The bayonet adds roughly a half‑pound, and the sling adds a small amount as well. Put those together and you land around 9 to 9.5 pounds.

The figure commonly used in training materials for this exact setup is about 9.5 pounds, which is why that answer is the best fit. Variations in ammunition type or magazine weight can shift a fraction of a pound, but 9.5 pounds is the standard reference for this configuration.
