What is the maximum effective range for the M16A4 rifle?

• A. 3534 Meters
• B. 3500 Meters
• C. 4000 Meters
• D. 3100 Meters

Answer: (A)

Max distance a round from the M16A4 can travel before impact. The 5.56×45 mm round used by the M16A4 has a maximum firing range of about 3,500–3,600 meters when fired at an optimal elevation, so the figure around 3,534 meters is the best match for that farthest distance the bullet can travel. The value reflects the limit of the ballistic trajectory rather than how far you can reliably aim and hit a target; the typical effective range for precise fire is much shorter (roughly 550–800 meters depending on target type). Among the options, 3,534 meters aligns most closely with the maximum range of the round, which is why it’s the best choice.
