I think it is transformable. Looking at anymoon blog pictures, there are tabs on the forearms and shoulder missiles pods. Also, the middle missile pod has a peg to peg the gun on it, but need to remove the magazine clip first. And...., the gun has a T shaped holes on each side, look like the magazine clip can be attached on it when you set the gun on the middle missile pod. Hopefully this also opens up a possibility that there are hard points on the wing to attach the gun.
