Miller point taken but it dose appear we were talking about a Boss gun. The topic strayed as is common and others had talked about "shimming " etc . The majority of guns that I have worked on all have some facility to have the lever come to a stop .I am not familiar with some of the American made guns to which you were possibly referring . A down side to this method of construction is that when the bolt /bites wear the lever will not travel any further forward so that with continued use the bite wear rate increases and the net effect is that the gun will get progressively looser and will "shoot off the face " .
