[QUOTE="260nut, post: 754860, member: 40931"] The inside of the action is fine because I trued it and I could have reworked the mounting holes but didn't see the need when lapping serves the same purpose. In all reality, the actual amount of material removed is probably far less than it appears in the pictures. Just guessing, maybe .005-.007". I was using 800 grit compound so it's not like I was going at it with 60 grit sandpaper or something. My main objective was to show that they were not perfectly aligned. As far as what I used and the procedure, Brownells 30mm lap bar and 800 grit lapping compound. I installed the bottom halves torqued to 25 in/lbs. I let them self align to the radii. Apply compound to the rings and place the bar in them. Then apply compound to the uppers and install them only snugging them so that the bar still moves. I used a combination of side to side, front to back motion and as the bar moved more freely, I would snug the uppers a little. From time to time, I would remove the bar to check my progress and repeat as needed. It was an easy process and well worth it IMO. I did it to eliminate scope damage and for more uniform clamping pressure. [/QUOTE]
