What is the muzzle velocity of the Mk-19 machine gun?

The muzzle velocity of the Mk-19 machine gun is approximately 790 feet per second (fps). This measurement refers to the speed at which the projectile leaves the barrel of the weapon once fired. Understanding muzzle velocity is crucial for gauging the weapon's effectiveness, accuracy, and range. The Mk-19 fires 40mm grenades, and a muzzle velocity of 790 fps is sufficient to allow the round to reach effective ranges for engagement while also accounting for the specific ballistic characteristics of the grenades it fires. The other options listed do not accurately reflect the Mk-19's muzzle velocity, which has been tested and documented as being around 790 fps.
