see how they don’t line up? how can I fix that?
here’s my heirarchy
Are you referring to the fact that the muzzle flash isn’t where it’s supposed to be, or that the handle is not at the center of the gun?
To fix the muzzle flash (muzzle, not mussle BTW 
) simply reposition the muzzle gameobject.
If you were referring to the handle being in the wrong place, it’s because unity is “averaging” the position of the point light with the position of the gun. Try selecting the armature object instead of the M16 object.
Hope this helps
don’t worry I fixed it and no it wasn’t what you thought it was.
