The M203 Grenade Launcher is a small Grenade Launcher that can be attached to the bottom of the foregrip of an M16 or an M4. It is a breech loaded weapon that fires one round at a time. It must be reloaded after each shot. In the US military the M203 replaced the standalone M79 grenade launcher in the late 1970's and early 1980's. Both weapons fire 40mm grenades. The M203 is capable of firing high explosive (HE), signal flare, chemical, and nonlethal rounds.
