Which pairing correctly matches the MK19 rapid rate with its burst pause?

• A. 60 rpm, 3-5 end burst, 2-3 sec pause
• B. 40 rpm, 3-5 rd burst, 4-5 sec pause
• C. 450-550 rpm, continuous burst
• D. 325-375 rpm, continuous burst

Answer: (D)

The rapid firing setting for the MK19 is defined by a rate of about 325–375 rounds per minute. At this speed, the doctrine describes firing in continuous bursts rather than requiring an enforced pause between bursts. In other words, you can keep firing in a rapid stream rather than stopping after a short burst, within practical limits like ammunition supply and overheating. The other options either use rates far from that rapid-range or imply a mandatory pause between bursts that isn’t prescribed for the rapid setting. So the best pairing is 325–375 rpm with a continuous burst.
