Mine just got back from g'smith amd I checked with calipers and dial gauge. Play in the lever at full open is .125 left or right or .250 total. Play in breech bolt is .018 when measured from port side and holding bolt hard against the receiver on the other side with bolt in the half open position. The screw in the hinge can only be tightened into the bushing and this produces the small amount of relief to keep the lever from sticking at the hinge. If you are interested I can measure the relief with a feeler gauge
