Dahermit's right and so is the boogieman (you didn't hear that kids).
Locktite used properly does exactly what it is designed for, not letting screws become loose from vibration, I use the blue locktite of every base and ring combination, and I swear by it, My scope are zeroed once and through the years they stay zeroed, no problems. Lubricating machine screws and proper torque also works for me unless there is pounding recoil, then I like to locktite them "properly".
