My gunmaker told me to put the thread locker, whatever you use, on the top of the screw head so it runs into the gap between the sides of the screw head and the ring or base. That way you can get them out and seals from water penetration. After reading MD's book I don't farmer tighten the ring screws anymore, hard habit to break, I grew up on a cattle ranch. As per GaryVA torque is measured w/lubricated surfaces.-Muddy
