What is the sustained rate of fire for the Mk-19?

The sustained rate of fire for the Mk-19 is 40 rounds per minute. This rate is established based on the operational capabilities of the weapon and is designed to provide effective fire while managing the heat generated during prolonged firing. Sustained fire rates take into consideration the need for the weapon to maintain effectiveness over time without overheating or excessive wear.

Different rates of fire apply to varying contexts, such as cyclic and rapid fire, but the sustained rate is critical for ensuring the weapon remains reliable and effective during extended engagements. Understanding this sustained rate helps gunners plan their ammunition use and ensure that they can maintain proficiency while minimizing damage to the weapon system. Other rates of fire, while relevant, do not reflect the specifics of maintaining a consistent and reliable output during prolonged operations.
