Sir Khulu, For a Winchester rear sight base 4-5 threads engaged should do well with your Loctite. If not: J-B Weld. I had a Ruger No. 1 quarter rib (rear sight, scope and rings for recoil action-reaction abuse) come off the barrel of a .475 Linebaugh factory Ruger No. Never a problem after J-B-Welding.
