"Makes everyone's favorite AR just a little better by enabling an attachable grenade launcher and silencer."
Sirius's GP 37 (G36) Grenade Launcher Mod
Unzip the contents of the .zip gamedata folder into your game installation's gamedata folder. (The only file in this mod is w_g36.ltx, which should end up in the gamedata/config/weapons folder.) You don't have to begin a new game.
This mod allows the attachment of both the M209 grenade launcher and the silencer to the GP 37 (G36) assault rifle. As the description of the M209 states that it can be attached to the GP 37, I figured it should be able to. There is no bug with aiming in this version, i.e. you raise the scope to your eye to zoom in rather than pushing it down like you do for the grenade launcher.
Feel free to use/distribute/include this mod as much as and however you want, so long as you do not profit from it. If you're feeling nice, you can credit me for it. - SiriusStarr

v1.1: Added better sound for silencer (Vintorez, rather than old AK 74).
