Worked on it today. No luck. New o ring, although the old one looked fine. No interference from scope base screws. I did polish the action bars with 600 grit wet paper, no rough spots at all now. Still doing the same thing. Slide pulled all the way back, action open, you can hold the rifle by the foreend and it won’t close. A couple jolts and it will close. Any 7600 I ever had closed way easier than that. Maybe I’ll try Ballistol.
