My Omega has decided to become one of the ones that will not return to the original settings every time the stock is removed. It is a synthetic one. I have considered pillar bedding but have thought about threading a solid aluminum rod and then drilling the center. It would allow drilling and tapping the plastic stock which would make the installation much more solid with little chance that the pillar glue would break loose. Anybody done this?? I found that even using a torque screwdriver does not totally fix the problem with drifting groups. Personally I would not recommend a plastic stock on the Omega since having this experience.
