A bit late to reply, but, yes, the instruction manuals explain that the screw is a bolt stop that should be adjusted to make the bolt stick slightly, then backed out until the bolt does NOT stick. I sold a wonderful Custom Grade to a friend who obviously was less disturbed by the well to the left lever position of the low mileage gun than I was. Obviously, someone, probably the original owner, had run the screw all the way in when the gun was new and it probably only took a couple of thousand rounds for the bolt to find its way to the end of its travel. The result was that the top lever took on a position that resembled a gun that had been fired hundreds of thousands of times.
