d5dz82 Not really. Only problem is the outer surface of the lower is too wide for the anti walk pins. I need to put together a counterbore block for this. The LR-308 release has them, which you could use. However, due to the coordinate system being different, you would have to manually align the blocks.
With bushings its easier as you can just drill through (in stages) prior to installing the bushings. Drill the printed holes up until the screw heads will fit through, and flush against the bushings.
