I dont remember if anyone has tried this, but it seems to work. I just used my G1 Mirage launcher and missile.
Man, that don't look half bad! Sadly I don't have one. Looking forward to all the weapon upgrade sets though
There is a clip that mounts to G1 Mirage shoulder which is a tube. I mounted it the same way. Only thing though. the wheels/suspension gets in the way so it cant point forward.
