Just a little tip that seems to work good for me....... sneek into the ol' lady's make up stuff and get some fingernail polish.Be sure the receiver threads are free of oil, put a little on your threads of the mount screws and install before it dries. Tighten to desired amount and allow to dry for a couple mins. They you're ready to go. It's just enough to keep screws from walking out, but releases easy enough you don't even hardly notice it's there when its time to remove.
