[QUOTE="Will Gray, post: 1935229, member: 65116"] Yes a gunsmith set of screwdrivers is right. If you do not have those get a good screwdriver that fills the screw slot end to end. With the screw out so you can check the fit to the bottom of the slot, grind the blade so it is parallel and fits the screw with some resistance. Good to have it tight enough so a light tap or two force the blade to the bottom of the screw slot. Press down firmly while tightening, keeping the screwdriver in line with the screw. You will be able to torque the screw with no damage to the slot. Save that screwdriver for use only only on those screws. Best to use a torque wrench so grind a bit fits your wrench. I recommend you change all screws to Torex style, getting away from hex head screws (Brownells sells screw sets). No Loctite of any color on my gun screws! Use bits that fit tight. Use penetrating oil on scope base screws from inside the action and tap the bit lightly with a small hammer to shock the screw if more than 30 inch pounds of torque is needed to remove the screw.
