What is the sustained rate of fire for the M16A2?

1. 10-12 Rounds/Minute

2. 12-15 Rounds/Minute

3. 15-20 Rounds/Minute

4. 8-10 Rounds/Minute

The correct answer is: 12-15 Rounds/Minute

The sustained rate of fire for the M16A2 is defined as the maximum number of shots that can be fired accurately over time without overheating the barrel or compromising accuracy due to rapid firing. For the M16A2, this rate is typically recognized as 12-15 rounds per minute. This rate allows for effective fire while considering the need for controlled shooting to maintain accuracy and avoid excessive wear on the weapon. This increased rate is facilitated by the M16A2's design features, such as its improved cooling systems and the ability to switch to semi-automatic fire, which help manage heat generation. The sustained rate is a critical aspect for Marines during engagements, as it balances firepower with the operational requirements of maintaining barrel integrity and accuracy.
