Need help with Garand rear sight problem

[kikokat]

Attachment 14526I could use some help with windage adjustment on my Garand. Either I'm totally confused (always a distinct possibility), or my rear sight has a problem. I finally took my HRA to the range yesterday to see how it shoots. Was shooting at 50 yds, trying to get it in the ball park for 100 yds. Unfortunately, I did not note the position of the windage adjustment before I fired the weapon

The first group I shot was about 2-3" high, and 4-5" right of center.

I adjusted the windage left 2 clicks, and the next group was approximately 5" left of center (Approximately a 10" total movement to the left)..

I next went right 1 click which only moved the group about 1" to the right (still about 4" left of center).

I then adjusted right 8 clicks which moved the group right about 3" right (still 1" to the left of center). At this point, I had my friend try and adjust the sight thinking I was having total brain fade. Still no luck.

Since I'm obviously not too knowledgible on Garands, I'm hoping one of you gents can offer suggestions as to the problem & solution. Is it just me, or do I have a mechanical problem with the sight? I certainly appreciate any help you can provide.

I attached a pic of the rear sight at the conclusion of my shooting which shows the position of the marker with the rifle still shooting 1" left of center at 50 yards.

Thanks in advance.

Twice this week I too have had the same problem. Both times the front sight was loose and moving on recoil. It was driving me crazy until the sight fell off making the problem obvious.

Attachment 14582Thanks for your response, Stumedic. I'm feeling rather stupid this morning after getting the garand out for another look, only to find the front sight on the verge of falling off. Can't believe I didn't think of that at the range.
Oh well, it could just be senility.

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 M1), 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.
