M203
From Wikipedia, the free encyclopedia.
M203 generally refers to the U.S. Army's designation for single shot 40mm grenade launcher that attaches to the m16 assault rifle. Stand-alone variants exist, as do versions capable of being used on many other rifles. The device attaches under the barrel and forward of the magazine, the trigger for it being just forward of the magazine. The magazine functions as a handle of sorts when firing for the M203. A seperate sighting system is added to rifles with the M203 as the rifles regular sights are not matched to the launcher.
