Anything is possible it you have enough money and a talented machinist.
An airsoft grenade does not explode, it launcher BB's out of the launcher powered by gas.
Simply refill them, yes.
It's about 350. Has very good range.
its not a grenade it just looks like a grenade launcher. it just shoots one bullet at a time
yes
If the smoke grenade operates on impact, then yes. However, it is a bad tactical idea, because if you have the desire to use a smoke grenade, then you are in the situation where you have enough time to pull one out.
The cartridge is called a grenades, usually 40mm or 32mm.
With the right mounts you could probably mount a grenade launcher on a Crossman, but why. If you need a grenade, you probably also need more of a gun than a pellet 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.
Technically, the ICS M203 Airsoft RIS Grenade Launcher will fit on the RIS rail below the barrel of the JG G36c. But it will not be a great fit. The RIS rail and barrel are very short and the launcher is long for this gun. Also, the launcher will get in the way when installing/removing the battery unless removed first. You can do it, but it may be more trouble than it's worth.
