I hope you get some answers on this one as I am interested in a laminated stock myself. When I do find it necessary to take my Omega apart Iuse a torque measuring screw driver to put it back together it has mantained excellant accuracy and the same impact point with out any problems. I have noticed that many people over tighten the stock to barrel and recoil lug screws on guns I have worked on. If I might offer a suggestion check the barrel channel to see if its humped any at the screws. Lee
