M1 Sights

[Moress]

Hello all,

So when I took my M1 Garand out for the first time, the little screw on the knob that holds whole thing together was loose so I had to go about readjusting the whole thing from scratch. Luckily, there was an older fellow there who gave me lots of help, but being a young'un, there was too much valuable information coming at me too fast to soak it all in.

Anyway, we sighted it in at 100 yards. We unscrewed the screw, turned it all the way down, then up about 8 clicks and it was dead center at 100 yards. My question is, how many MoA's is each click? I can't remember if he told me 1 or 1/4?

Also, I'm using M2 Surplus ammo, and I think the older gentlemen had me sit my 100 yard zero at the '4'. Would it make more sense to set it to the '1'. instead so if I wanna shoot at 200 yards or 300 yards I can set the knob to 2 or 3?

Thanks!

Forget about setting the numbers on the knob to corespond with distance. The screw will com,e loose someday and you will loose you zero.
Its better to get a zero at 100yds, once you have this slowly turn the knob/apeture down counting clicks. Lets say its 8, write this down :8 clicks 100yds
Now turn apeture up to 8 clicks which is 100yd Zero, try adding two more which is 10. Shoot at 200 yd target, youshould be close. Go ahead and fine tune the 200 yd zero and write it down, etc, etc, etc.
Put this piece of paper in the trapdoor of the buttstock.
This way if you loose your zero all you have to do is refernce the piece of paper instead of rezeroing your rifle.
FYI, you do not loosen any screws to turn the windage or elevation.

Isn't the screw thats suppose to take a flat head screw driver on the left side of the sights (The eleveation knob) the screw that you untighten to free the elevation knob though?

No, both the elevation and windage can be changed without loosening anything

Orlando is 100% correct on using the number of clicks from the bottom to get your starting point. I had the exact thing he described happen to me a few months ago. I went to the practice session at the 1,000 yard range at Sac Valley in January with my newly rebuilt Garand and shot at the 200 and 300 line. When I got to the 450 line, I went to come up on the elevation and the screw just spun... I had no clue where I was and where to go from there.

Now I don't worry about the numbers on the knob, I know for sure my rifle is dead on at 100 yards at 8 clicks from the bottom, and I just go from there.

Wouldn't it just be better to remember the number of clicks set to zero then always set it to the corresponding number so you don't have to log the number of clicks for every different range setting?
