No. The M203 is a grenade launcher.
CLP, same as what's used on any rifle.
The M4 3181 AEG electric rifle with M203 spring grenade launcher typically has a magazine capacity of around 300 rounds.
if you mean a rifle mounted grenade launcher (like a M203) they are sorta useful it really depends on the situation
Well, it is a 40 mm grenade launcher if you mean the real rifle and the M203 launcher- but there is NO ONE BEST. The M16 is a good rifle- but it will not be a 1000 meter rifle. And it may not be the rifle of choice in close quarters, or where greater penetration is needed.
From US Army FM for the M203: The M203 grenade launcher is a lightweight, single-shot, breech-loaded, pump action (sliding barrel), shoulder-fired weapon that is attached to an M16 rifle series (Figure 3-1), or the M4 carbine series with the M203A1 (Figure 3-2), and M4 carbine series with the rail system (Figure 3-3).
It's about 350. Has very good range.
Could be a rifle, shotgun or handgun.
shoot it in the head with a 30-06 rifle or any high power hunting rifle.
The 'M4 3181 AEG FPS-300 Electric Airsoft Rifle, M203 Spring Grenade Launcher' is a HOT airsoft rifle. Not only does it offer a high power electric machine gun that shoots full or semi auto, it also has a grenade launcher. It is priced around $90, not bad for a rifle and grenade launcher.

The "Grenade Gun" found on the M16 rifle is called the M203 grenade launcher. It is used by manually opening the loading port, inserting a 40mm grenade, closing the port, and depressing a separate trigger. The M203 will then discharge its grenade at the intended target. Further detail is not (in my opinion) necessary for this answer.
