Objecto to follow tracked motion track path - easily?


I made muzzle animation with tutorial. I also put video to the background and made tracking in “Motion Tracking”-layout.
Is there any easy way to get this muzzle to follow tracked path?
It is now only blue and red points in “Motion Tracking”-layout window and animation is in “Default”-layout.


Need much more information.
what tutorial?
did the muzzle do a dance or what?
muzzle flash?
