Because of its weight, the MK19 40mm Grenade Machine Gun is crew transportable only over short distances with limited amounts of ammunition. The MK19-3 shoots a 40mm grenade, which can kill in a 32-foot (5-meter) circle and wound in a 100-foot (30-meter) circle (48 feet). The grenade can penetrate two inches of armor.
