I shot an entire weekend clinic of three-position with my scores ruined by a drifting front sight. The first day I was working up to a great score and my technique was really improving when all of a sudden I couldn't get the bullets to go where I wanted to save my life. That night, while cleaning the weapon's muzzle (not an M1icon), I felt the front sight shift. Marvelous. Lock-tited the set screw and considered the problem over.

The next day I started strong and then as I began to really drill in, my scores went to hell in a hand basket again. Of course, because of all my work with the sight the night before and my confidence in my fix, I couldn't consider the problem to be the same one. Doh! That night, dispirited with my scores, I was cleaning the rifle again and discovered that the silly sight was loose again even though the set screw was good and tight. No matter how hard I torqued down the screw, the sight could still move. I ended up making a shim that tightened down the tolerances.

I'm a little surprised that none of the instructors figured this out. Oh well.
