M203 Compilation in Movies & TV

The M203 grenade launcher is an underbarrel accessory grenade launcher originally developed as part of the SALVO / SPIW projects, a series of trials to produce an advanced rifle for the US Army. A sub-project, NIBLICK, produced a lightweight, low-recoil 40mm grenade round using the high-low pressure venting system devised by the Germans in WW2, and initially developed the M79 grenade launcher to fire it.
