Ive known about how to tighten up the rear sight for years on the M1. The basics, that is. The screw in the elevation knob needs to be really tight, the tooth on the elevation knob needs to be sharp and not worn, the spring inside the elevation knob needs to not be worn out and you do the basic tightening by tightening the windage elevation knob one click at a time until it wont rotate, then back off one click.
OK...simple there. But to get it even tighter, more mechanically repeatable.
I bought the Jerry Kuhnhausen shop manual from Brownells about a month ago. Ive been reading the section on the M1 sights with fascination. It is my opinion that the weak point of the M1 Garand is the rear sights, specifically the elevation dropping and moving under heavy recoil (mechanical repeatability). I learned about the rear sight spring cover need to be pressed down into a curve to be pressing against the aperture and rear sight base as being key to having a stable (repeatable) rear sight under repetitious recoil.
But here is the part that I find fascinating. Annealing the rear sight base with flame and packing Brownells heat stopping paste into areas of the rear sight base that dont need the annealing. And then letting it cool, grease it up and insert a greased aperture and put it in a vise upside down and slowly, very carefully tighten to get the aperture tighter fitting.
Anybody here done the annealing rear sight base guideways thing with Brownells heat stop paste before? If so, did it make your rear sight mechanical repeatability rock solid?
