M203 generally refers to the United States Army designation for a single shot 40 mm grenade launcher that attaches to the M16 assault rifle or the M4 Carbine. 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 separate sighting system is added to rifles with the M203 as the rifle's regular sights are not matched to the launcher. The M203 can fire high-explosive, smoke, illuminating, buckshot direct fire, CS gas, and training grenades.

History

The M203 was introduced to U.S. military forces during the early 1970s, and replaced the older M79 grenade launcher. However, while the M79 was a separate weapon entirely, the M203 was designed in order to increase the efficiency at which a soldier could alternate between bullet fire and HE grenade fire.

It is sometimes thought that the M203 was a poor replacement for the M79, as while the M79 was quick to reload and more or less accurate under adverse conditions, such as in Vietnam War, the M203 was more difficult to operate, and could be sent off-target more easily by variables such as a gust of wind.

A new grenade launcher in development, the XM320, will likely replace the 203 in United States service eventually. The XM320 weighs more than the M203, but has some added benefits.

The 40 mm grenades used in the M203 are not the same as in the Mk 19 grenade launcher, which are of higher power.

Components

The M203 Grenade launcher system comes with a variety of components, usually including the launcher, adaptors for attachment to assault rifles, and leaf sights (which can be used with the rifle's front sight post). M203s can also come with quadrant sights, mounting to a MIL-STD 1913 Rail, or to the carrying handle of an M16 rifle.

Variants

M203 target practice

There are numerous variants of the M203 manufactured in the U.S., and throughout the world, for various applications. These vary chiefly in the length of the barrel, attachment type, and quick detach (QD) capability.

The standard M203 is intended for permanent (armorer level) attachment to the M16A1, M16A2 and M16A3 rifles, and utilizes a 12" rifled barrel. These can also be attached to M4 and M4A1 carbines, using a different front attachment point forward of the front sight block, but the SOPMOD kit uses M203A1 grenade launchers.

The M203A1 is intended for use with the M4 and M4A1 Carbine. The barrel is shortened to 9", and principally the M203A1 QD is able to quickly detach from the rifle, and be replaced by a Knight's Armament Company M4 RAS lower handguard. An advantage of using a 40 mm grenade launcher on an assault rifle equipped with MIL-STD 1913 Rails is the attachment of various range-finding optics.

The M203A2 is intended for use with the M16A4 MWS (Modular weapon system). Using standard 12" barrels, the grenade launcher is intended for use in concert with the Knight's Armament Company M5 RAS. Again, an advantage of this system is the attachment of range-finding optics makes precision targeting easier.

The M203 Pi system is used for attachment of the M203 to other rifles, including but not limited to the Steyr AUG, H&K G3 and other rifles. Most of these other companies have since devised 40 mm grenade launchers custom integrated with the weapon.

Civilian ownership

M203 grenade launchers are classified as "Destructive Devices" under the National Firearms Act subject to the NFA process. M203s are not that common in the civilian NFA market because each explosive 40 mm grenade is also subject to the NFA process and its subsequent $200 tax. 37 mm flares are legal for civilian use without a NFA stamp, and 37 mm flare launchers have been built along near identical lines to the M203 launchers.

The M203 is known to the common man as "the shorter, larger gun under the M16 and M4" and has been used to defeat "bigger or tougher foes" in most films, TV series and video games. As with the M16 rifle, M4 carbine, M249 SAW and M9 pistol, the M203 is a hallmark of the modern American soldier.

Films

The M203 mounted on an M16 is the weapon made infamous in Scarface when Tony Montana says, "Say Hello to My Little Friend."

It also makes an appereance in both Predator movies, one on an M16 and one on a CAR-15.

The grenade launcher used towards the end of the James Bond movie Tomorrow Never Dies as Mr. Stamper tried to kill Bond aboard the stealth ship was an M203.

The M203 has been shown in cinematic depictions of modern US military actions, most notably Black Hawk Down and Jarhead.

A 'stand-alone' version of the M203 fitted with a pistol grip also made an appearance in the film xXx.
