Assault Rifle Add On / Grenade Launcher:
A grenade launcher has much greater range than a hand thrown grenade by a soldier. The trajectory of these types of launched grenades are high arcing, but are quite accurate at 200 meters. The M203 grenade launcher was an add-on to the colt m16 rifle.
The M203 grenade launcher was designed as a rifle attachment in order to increase the efficiency at which a soldier could alternate between bullet fire and High Explosive grenade fire. Standard grenade launcher round today is the 40mm grenade, and of course has many varied usages, anti-personnel grenades are used to repel larger enemy forces attacks.
In underbarrel grenade launcher systems, like the M203 that can be attached to the Colt M16 rifle, the rifle portion and launching portion of the weapon can both be carried loaded and ready to fire. Underbarrel tubes generally have their own trigger and use the rifle's magazine as a grip for the firing hand, and barrels have varied lengths.
For aiming, the M203 mounts either a flip-up rear sight, which is notched for different ranges and utilizes the rifle's existing front sight, or a quadrant sight which mounts to the side of the carrying handle.
To fire, one simply changes grips, disengages the safety and pulls the trigger. In most systems the barrel either slides forward or pivots to the side to allow reloading.
The standard M203 grenade launcher is intended for attachment to the M16A1, M16A2 and M16A3 rifles, and utilizes a 12" barrel. These can also be attached to M4 and M4A1 carbines. In the United States, M203 grenade launchers are classified as "Destructive Devices" under the National Firearms Act.
1. The M320 has a sighting system that features day and night capability out to 400 meters, unlike the M203 sight system which is designed for day firing.
2. The M320's launcher breech swings open to the left side of the weapon, so it can fire grenades up to approximately 9 inches in length.
3. The M320 features its own pistol grip instead of relying on the 30-round magazine of the M16. There is also a special stock that can be attached so it can be used in the standalone role.
4. The M320 features a double-action trigger, an improvement over the M203's single-action trigger. When the M203 is loaded, it is cocked and ready to fire. With the M320, the firing pin remains in the uncocked position. Pulling the trigger cocks the firing pin to the rear and fires it. This eliminates the possibility of a round going off if the weapon is dropped or bumped.
