An American single-shot, muzzle-loading [[40mm grenade|40mm]] [[underbarrel grenade launcher]]. It was designed to replace the [[M79]], which was a stand-alone weapon. The under-barrel design gave soldiers the advantage of having quicker switch of both [[rifle]] and [[grenade launcher]], making them more adaptable in combat. The M203 was originally designed designed for the [[M16]] and [[M4 Carbine]] but can be fitted to many other rifles without modification.
