Which statement accurately describes the MK19 sustained rate and burst pattern?

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

Answer: (C)

Sustained rate describes how fast you can fire over a longer period without overheating the weapon. For the MK19, this sustained rate is about 325–375 rounds per minute, which is slower than the weapon’s maximum cyclic rate but chosen to keep the weapon operable under continued use. At this sustained level, the pattern is described as continuous bursts, meaning you can keep firing in sequence rather than forced, fixed pauses after each short burst. This reflects the way the MK19 operates in extended fire scenarios: you manage heat and ammunition while maintaining a steady tempo rather than stopping after every small burst. The other options either imply rates too low for sustained operation or imply higher rates or mandatory pauses that don’t align with how the MK19 is rated for sustained fire.
