History:

The M203 has been in service since 1969 [2] and was introduced to U.S. military forces during the early 1970s; replacing the older M79 grenade launcher and conceptually similar Colt XM148 design. However, while the M79 was a separate weapon entirely, the M203 was designed as a rifle attachment in order to increase the efficiency at which a soldier could alternate between bullet fire and HE (High Explosive) grenade fire.
