Advantage 21st Century

In the process of adding a period correct sight to my Savage 99 it occurs to me that I have something that some users of these sights didn't.

Loctite.

All you had to hold a screw in place in 1951 was torque.  With the tiny 8-40 screws which attach a peep sight to the tang of a Savage 99... that's not much torque before something strips.

Insufficient torque to prevent the shock of firing from loosening things.

There are stories from WW1 of marksmen using acid on the threads of the screws holding their scopes to the rifle to prevent them from walking loose.
