Non-Dud Producing (NDP) training cartridges, MK281 and XM110 enable 24/7 day/night combat training on the high velocity MK19, MK47 grenade machine guns and low velocity M203, MK13, M79 and XM320 grenade launchers. The MK281 MOD 0 and MOD 1 are for high velocity, and the XM1110 is for low velocity. They are the first officially "green" 40 mm rounds adopted by the U.S. Armed Forces.
