Since we are talking about Omega "problems" I will add one that I found on mine due to another post that I have since lost track of. My Omega started to have big POI shifts due to stock removal (or so I thought). Someone posted a note saying to check the front stock screw mount as it is screwed to the barrel. I thought it was welded as the rear is but I was wrong. I never looked at that part of the rifle that closely before. Mine will turn left and right a little although the two screws appear to be tight. I plan to remove the screws add some epoxy between the mount and the barrel and reinstall the screws with blue loc-tite. I am not sure that this is the only reason for the shift but it certainly is not a desirable situation. I also bought a torque screwdriver which I am now going to use when removing and reinstalling the stock. The two screws are slightly burred which makes me think the assembly person did not do a good job since the screws have not been touched by me since I bought the rifle. Being able to turn the block with the screws apparently tight bothers me a little.
