M1 Garand Front Sight Adjustment

A short video about zeroing your windage on an M1 Garand using the front sight. Enjoy!

Nice detailed video.

Excellent info 👍. I heard a guy say that the CMP rifles are often chanted to the left have you found this to be true? Maybe he didn't really mean canted maybe just need to be drifted like you did? I always thought the M1 had a 28" sight radius is yours actually 30"? If you ad the NM hood you will have a 1/2 moa adjustment and you will be dead on at 200 zero. Excellent 200 yard group BTW Sub moa looks like? I am planning to get the CMP special grade because I am not a collector and want it for fun and hunting and possibly competition. Thanks

He meant drifted. Canted is usually seen on Aks where the front sight isn't symmetrically in between the two sight guards. Same with Arisakas and many other sight protector style guns. The garand cannot cant like the Ak because the sight guards are fixed to the sight. But yeah adjust the front sight for horizontal, then adjust the rear sight with a screw driver to set the elevation to be perfect at 100.

good video thanks

.008" movement equals one MOA on the front sight

I appreciate your insight. I will use your technique.

I tried to adjust by hand, and got kind of lucky to be close at first. Each attempt to adjust by hand was essentially a random adjustment. In the end, I am hitting about 2" to the right at 100 meters. So if I understand this video, using a caliper, I could move the front sight 20 thou to the right, and it should be fairly close to correct. Separate question, with the rear sight all the way down, I am still hitting about 4" high at 100 meters. Is this somewhat normal? Is there something I can/should do to fix that?

[@mdlanoll]

Hitting 4" high at 100 with the rear sight all the way down tells me your front and rear sight are not matched correctly. 100 yard zero should be at 8 clicks up from the bottom. I suggest you call Fulton Amory and ask a tech for help.

[@jshtaylor]

@@mdlanoll Well, I built this Garand from parts, the front sight appears to be a IHC, while the rear sight Springfield. So yes, mismatched. I thought the parts were standardized enough this wouldn't be an issue. Anyway, knowing how it shoots, I ca adjust my hold.

Love the wood on yours. Mine doesn't have that much grain. Is it a CMP or a Boyds?

[@James-ki6xi]

Dude, i wish my old eyes could shoot that good with open sights. Nice job

[@howardcollins9320]

Thanks for the video. Where are you placing the caliper when taking measurements with the depth gauge? I can't get a consistent reading.

[@Wundrdawg1]

Nice work man,... I appreciate your time and effort putting this together for all of us. It definitely helps. Happy shooting brother.

Finally found this video. You are right everyone shows elevation but very hard to find how to zero windage. Thank you. Just started hand loading for my M1 and the signage ran out right with no more left adjustment. This is spot on thanks again

[@jason200912]

is your rear sight purposely set to 225 yards or does it need to be fixed?

[@PRACERZ]

Fantastic, so well done 👍🏻👍🏻

[@stl1ajh]

Once screw is loosened, you say to "slide" the front sight. My front sight won't budge. I even removed the screw. I need to make minuscule adjustment and can't even get mine to move slightly. Any advice?

[@mdlanoll]

Tap it with a plastic hammer. It won't take much to move it 5/1000"

[@unclenick222]

Good video. I will point out that the little sticking-out thing at the end of the caliper beam is called a depth probe. It's usually for finding how deep a blind hole is. The reason you overshot the initial adjustment is you got the hash mark measurement a little bit off. The threads on the windage adjustment are 32/inch, so 4 clicks move the sight 0.03125" and not 0.040". The Garand blueprints confirm this, labeling the hashmark scale as 0.25" wide, divided into 8 equal parts. Dividing 1/32" into four clicks gives you 1/128 of an inch per click, or about 0.0078" per click. The direct way to calculate sight correction in inches on a target is to divide the sight radius in inches by the target distance in inches. The Garand sight radius at a 100-yard zero rounds up to 27.9", again according to the blueprints and before taking tolerances into account. 100 yards is 3600", so 27.9/3600=0.00775" sight shift per inch of impact shift on the target, which also rounds to 0.0078" per inch on target. For calipers, 0.008" is all you are likely to resolve anyway and will easily be close enough.

Thanks for the information.
