M1D Garand M84 Scope

Start by zeroing the rifle at 100m. Bring a good supply of ammo with you when you do this as it may take awhile to get it right. The adjustments are fairly coarse, so move each knob in small increments while zeroing.
Begin by placing the elevation knob on the "1" or 100m setting, and the windage knob at "0". Shoot a group. I can't recall the actual amount the scope is offset to left of the bore, but I think it's around 1.25". Adjust the elevation and windage scope knobs accordingly to zero your group so that it hits point of aim for elevation, and approx. 1.25" to the right of point of aim for windage. After that is accomplished, we need to zero the scope knobs WITHOUT moving the reticle so that you can use the ranging feature of the scope. Provided its an actual U.S. G.I. scope, to zero your scope adjustment knobs for windage and elevation, you loosen the turret screw on each knob while holding the turret knob from turning and then lift up on the turret knob and turn to desired marking. So, if you zeroed at 100m, then you will want to turn the elevation knob back to the "1" or 100m setting, and the windage knob marking back to "0".
As for why the windage is not adjusted to be dead on the aiming point, it's because with the scope offset to the left, if you zeroed windage to point of aim, the rounds would start impacting to the left of your aiming point at any distance greater than what you zeroed at.
I hope this isn't too confusing...

Actually it is quite surprising how little information there is out there on the use/zeroing and employment of the M84 sniper scope. I suppose a scope is a scope and they all basically work the same but my M1D is the first scoped rifle I have ever owned, I have no experience with scopes. Thank you
Elvis3006: To avoid frustration and wasted ammo at the range (and because you can't borsight a Garand) you might consider buying an inexpensive laser boresighter. You stick it in the muzzle and adjust the sight to correspond to the red dot at 25 yards, or so. Will usually get you on the paper right away. I have an M1D that I've been meaning to get to the range so I'm glad you brought this up.

You can boresight a lot of semis by using the little angled bore inspection tool made for the Garand.
I just looked up the one I have,USPM---us7790138.
You just open the action,put it in the chamber and like a little periscope it allows you to check the bore and
of course boresight.

Went to the range today with the M1D and used the info gained on this thread and it worked. Was able to adjust and confirm elevation but before I could get the windage sorted lol I noticed that the screws securing the scope to the mount were loose, I stupidly forgot to check tightness before firing. After 8 rds the clip failed to eject and quickly noticed that the scope had moved forward causing a portion of the rubber eye piece to block the bolt/breach area preventing proper ejection of the clip as well as preventing re loading. Well at this point I remembered that I forgot to bring my tool kit which had the Allen wrenches in it lol. So I removed the scope and used the iron sights and zeroed the rifle. I see another range trip this week this time with my #### sorted. I want to thank those here for the info.
If you find the scope a bit of out of focus, do not dispare.
I have repaired several M84 scopes and the repair manual says that they are left to be slightly out of focus to allow for dust ??
I found this very strange, but in my experience with them they are a real bugger to set the focus as all the insides are aluminum and it galls badly
plus it sheds aluminum oxide.
Just my .02 and some experience with them.
