When rebuilders of car engines torque down the heads they relieve stress by giving the bolts a rap with a hammer. Not sure you should or can do this with ring screws but I do use both Lock-Tite AND use enamel paint to show if the screws have moved. I will remember to back the screw rings out before I re-tighten them.
Again, please know I am new to rifle shooting and came from the world of 1911's but I have found the enamel paint very helpful if the screws have not stretched internally.
Do you use Lock-Tite?
As a newbie does the enamel paint really make a difference?
