Scottish Resistance for Grenade Launcher

Here we are once more. This time around, I ported over the Scottish Resistance over to replace the grenade launcher. Uses proper animations not broken ones.

Please report any problems ASAP so I can fix them.

IMPORTANT: If you plan on removing this model or installing another one, you must remove the c(underscore)demo(underscore)animations.mdl from models\weapons\c_models. Failing to do so will result in broken animations.
