M203 Grenade launcher fitted onto M4

This standard M203 grenade launcher fits perfectly on your m4 carbine!


1) Choose the weaponinfo.xml of your choice:
 -The first one acts as normal, one grenade for one shot,
 -The second one has 2 grenades a clip, because he looks
 like he is loading 2 grenades in after all,
 -If you are feeling particularly crazy, and think you can
 wield this weapon while driving a car and kill tons of bad guys,
 use the third one.

2) Rename it, "weaponinfo.xml".

3) Put it in Grand Theft Auto IV/common/data/ (make a backup first! )

4) Use an img opener like Spark IV or Open IV to open PC/models/cdimages/weapons.img, and import both w_mp5's	

5) Open GTA IV and play!


1) This replaces the mp5 with an M4 with a grenade launcher on it.

2) You have to have both the mp5/"m4 with m203"(you can tell by the icon) and the regular m4.

3) Switch to your M4, and when you want to blow stuff up, scroll down on you mouse and unleash hell!

Bugs (unfixable until animation modding comes about):

Niko loads 2 grenades into his grenade launcher.
Niko always forgets that the grenade launcher is already fitted on to the M4, and always
puts the gun in his clothes before remembering.
The grenade launcher is invisible.


This is my modification, and posting on other sites without permission is prohibited.
The m203 icon is made by me.
The scripting was done by me.
PM me on GTA Garage or GTA Forums or contact me at [email protected] to ask for permission.

Great job. If someone could make a M4 with a actual GL that you can see that would be even more kickass :colgate:
