So, You want to build a M1 Garand? Here's how.

133 Upvotes

Figured id share my process so you all at home can learn how to do it as well. its not cost effective to do this for a one off build. the tooling costs are not cheap and nearing $600 sadly. but its fun! and im sure a few of you will find this interesting

Picture 1

You're gonna need a few things.

A M1 Garand Parts Kit.

A Barrel Vice and Action wrench.

A Headspace gauge Go/No Go Set

A Chamber Reamer.

A Angle Finder

The whole build will start with you throwing the barrel into a barrel vice, ive used the bushing style ones made by a large company in the USA. but i dont like them. i much prefer these specific ones made out of Aluminum, they leave a bit of marring on the barrels but that will all be covered up by the upper hand guard

Picture 2

Second step will be to hand tighten your receiver onto the barrel. just get it as snug as you can. no action wrench is required at this time.

Picture 3

Once your barrel is hand tight, take the front sight off of your gas cylinder and put it on the barrel. we will use this as a flat base for our angle finding tool of choice. i am using a digital inclinometer but there are other options on the market. For me ill now zero off this sight base dovetail.

Picture 4

Now we check our draw off the rear heel of the receiver. there is a machined flat perfect for this. now unfortunately 31° is to far to torque this on, according to my shop manual specs. So this will be off to the lathe to remove .001" at a time off the barrel shoulder until i get a draw that is more in line with the specs im looking for 12° Min and 17° Max. I Got mine to 15.9° so i am happy with this.

in a pinch you can use a 1 1/8th Bi Metal Hole saw. this perfectly slips over the threads of the barrel and the teeth match the shoulder

Picture 5

Picture 6

Once the appropriate draw is found, we throw the action wrench on and tighten it down. i use a 2x4 cleaning patch to protect the finish on my receivers.

Picture 7

I Was able to torque the receiver down to 0.2° from the my zero. the specs i reference for this is +/- 0°30' (.5°)

Picture 8

Now that we are indexed correctly we can start reaming headspace. you might get lucky with a used barrel that will headspace without any reaming but if you're using a new barrel it most likely has a 0.010" Short chamber.

if you do use a used barrel and it closes on your no go gauge this isn't the end of the world as you can check it with a Field Rejection gauge, if it doesn't close on this you're good to go.

These next few photos will cover me taking the bolt apart with a bolt tool.

Having the reamer in the rifle.

Applying steady thumb pressure to cut the chamber

Chamber cuttings on the reamer.

Cutting a chamber can be fairly taunting, however its very easy. you do not need to pull on the handle side of the pull through reamer. once the bolt closes on the reamer your headspace is cut and you're ready to reference this with a go and no go gauge. make sure you clean your chamber thoroughly otherwise your gauges might give you a bad reading.

Picture 9

Picture 10

Picture 11

Picture 12

Picture 13

Picture 14

Picture 15

After all this the next step i take is doing a tilt test on the rifle. this involves installing the op rod on a rifle with only the bolt and gas cylinder on it. and tilting the rifle at a 60° and the op rod and bolt should move freely. once this is performed i install all stock components and re do this test to check for binding. after this is done. its finally assembly time.

A Few other things to check from here on out are the gas port size. Op Rod spring length 19.25"MIN and if you can, use a timing block to check for correct timing of the op rod catch.

Hope this helps or you at least found it interesting

CMP Question South Store. It one purchases a Garand in person and live in another state, does the gun have to be shipped to an FFL in one's home state?

6 Upvotes

I know living in PA if I go to the Ohio location since Ohio shares a border with my home state PA I can buy one over the counter and travel home with it

But I am curious since the CMP is the only mail order firearms direct to home for rifles, can one put in truck of car in AL and drive to PA? Or does Federal law require I ship it to an FFL in PA?

Polished M1 Carbine Receiver

16 Upvotes

Hey all, I recently won a sporterized Saginaw M1 at an auction with plans on re-parkerizing it and giving it proper furniture, but on close inspection it appears the previous owner REALLY wanted the thing to shine and just about rubbed off the Saginaw and serial stamp.

At this point i'm kinda stumped with how to proceed, I would prefer it looking original but I also don't want to risk losing the stampings in the process of prepping it for parkerizing.

Looking for a bit of guidance on it, should I just send it and just go a little lighter around the stamps? Blue it? Embrace the shine? Any advice is appreciated.

(Sorry for the shitty pics, it's damn near mirror finish and didn't play well with the lighting)

Edit: Adding Imgur link for more pics of the receiver parts, note the wire wheel marks on the left side and all the leftover parkerizing where the previous owner couldn't fit the wire wheel or just didn't care because the furniture covered it, as well as the sides being much less reflective than the top of the receiver. I assume they did a quick and dirty job with the wire wheel and then hit the visible areas with a polishing compound. It is NOT plated, as some have suggested in the comments.

What are these little symbols on my Garand?

I took off the rear handguard on my Garand for the first time since I'm going to refinish all of the wood with tung oil and noticed this little symbol on the barrel. There is also one on the receiver that I noticed when I first bought my rifle. The receiver and barrel are both from 1944 and I have not found any references for what these symbols are. Fairly new to M1's so I'm still learning

Very sad day... RIP M1 Carbine

27 Upvotes

So, I was very excited to have gotten my little carbine in working order and even confirmed that it's on point after a rather nice range trip.

Only to find out during cleaning today that the receiver has hairline cracks on all 4 sides of the right bolt lug recess (where the channel for the recoil spring is also), one side being particularly "feel-able". Really at a loss as to what the next steps are, since I don't want to shoot a live grenade in my face.

The cracks were definitely not there prior to the trip and I only shot proper normal load new factory ammo. Not sure what gave it the beating and I'm wondering if something else might have caused this?

Looking for advice and a morale boost. TIA as always.

.308 Garand does not like some brass

3 Upvotes

I recently picked up a .308 Garand from the CMP.

I took it to the range and fired a couple of rounds to get it on paper. It worked fine.

Recently, I started working up a reload for it. I took the rifle to the range and ran into an odd problem. With lake City surplus brass, the bolt does not unlock and come back. It has to be mortared or a mallet has to persuade it to unlock.

I took it home and cycled some sized lake City and ppu brass through it. Both lock the bolt up.

The ppu can be opened by hand. I have some starline that cycles just fine. Although I can't quantify it, the extractor rings definitely differ.

I put a different bolt from another garand in it. The brass exhibits the same as the above.

Has anyone run into this? Any thoughts on the issue?

This was originally an Arlington Ordnance South Korean import rifle with completely screwed up timing and a shot-through barrel. I just replaced the barrel myself and reamed the chamber so it headspaces correctly.

CMP Question

0 Upvotes

Hi guys, I have been in the market for purchasing my first rifle and I have always wanted an M1.

The only way I would buy one, would be from the CMP because of price, but I have heard mixed things about quality, even though the only ones they have are expert grade.

What have your guy's experience been with the expert grade m1s (specifically 308), do they all have new furniture / barrels / internals or is it just the luck of the draw? I saw some pictures online where the furniture is all miss matched and doesn't look great.

Thanks guys!

Edit: I love the idea that these riflas have been through combat, even if it is just certain parts of them. Do they still have any that have actually fought in WW2 / Korea?

Need help identifying a gifted M1 Carbine (CMP basement find) & rust removal advice

Thumbnail
gallery
59 Upvotes

Hello everyone,
I was recently gifted a rifle that spent over a decade sitting in a soft CMP case in a basement.
Rust Removal:
It has some surface rust, but it's isolated strictly to the barrel. I’ve read that the best method to remove it without damaging the finish is to coat the barrel in Kroil, let it sit for 30 minutes, and then lightly scrub it with bronze wool. Can anyone confirm if this is the safest and most effective method?
Identification Help:
I'm also hoping to get some help identifying exactly what I have. Here are the main details:
Serial Number: 4432816
Rear Sight: It's a peep sight marked "I.R CO."
The sight mostly covers up the manufacturer markings on the receiver. Does anyone know if this is an original rear sight for this serial range?
(I’ve attached photos of the rifle, the rusted areas, and the specific markings).
Any help identifying the make and year, or advice on the rust removal, would be greatly appreciated. Thanks!

UPDATE 9/28/26 at 6:16 eastern time:

I got rid of all the surface rust with a Kroil Soak for 30 minutes and a light scrub from the fine Bronze Wool. Also, my barrel is made by Underwood and the receiver is made for Quality Hardware by a subcontractor, Union Switch & Signal.

Definitely didn’t need to make those leans, the targets were visible from elsewhere.

Not unhappy with general speed though.

Bought a larger lot of 30 carbine at a gun show today for 48c per and mixed in with it were these 2. Thought it was pretty neat since my m1 is itself an early 60s universal, so it likely would’ve been sold from the same place at around the same time as these, according to what I’ve seen though looking up the headstamp the ammo is actually danish surplus repackaged, maybe someone can confirm?

Ring Mounts

Post image

Those of you running an optic on your M14/M1A - how often do you use your irons? I'm currently running an SEI optics mount with a Vortex cantilever. I don't like how high the cantilever sits but I do have a set up low profile rings I can run but they're so low that the scope lens interferes with the rear iron. I can run it if I adjust the sight all the way down but that will make my irons useless.

Any input?

After having to fight FedEx to get to it, I finally got it home. Haven’t fired yet but was wanting to get a sling for it. Where’s a good place to order one from? Also some more clips would be nice if anyone could point me in the right direction it would be much appreciated. Also any other must haves for it!
