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

Rainy day project
While going through some spare parts for carbines I own, I realized I have enough parts to throw together a shooter carbine and I’m half tempted to do it provided I can find a receiver and barrel, or even better a barreled action. It is a total Heinz 57, with an Underwood trigger group (guts are QHMC except an Underwood trigger and IP sear), Underwood bolt (SG extractor and Inland firing pin), Rock Ola wood (stock is Rock Ola for QHMC that went through a rework at Underwood, metal’s underwood too), and an original flip sight and Type 1 barrel band. I do have other parts on the way such as a front sight with the goodies for it, Underwood slide, gas piston and nut, and recoil spring guide coming. My goal is to make a shooter with as many original GI parts as possible, but I can live with some commercial stuff like say if I found a close enough to GI receiver and barrel. Of the parts I have currently, the only repros are the sling and oiler from At The Front. Really looking forward to this project and giving my West German police Inland a friend in the safe!

Clip Latch Not Able to be Depressed
Hi all,
I am having a bizarre problem and I am not able to find any sources to help. Backstory, this is my M1 I built at the CMP Advanced Maintenance Course. It runs problem free besides from a weak clip latch spring which I replaced with a Fulton Armory HD Spring. However, the only problem I am having now is that whenever I have saved rounds (which is hopefully never), I am unable to eject a full or partially loaded clip in my rifle. I can press and press on the clip latch and it just will not budge. The only solution I have found is physically hitting the clip latch with a rubber mallet which will cause the clip to eject. Obviously this is not practical and I’d prefer to not beat on my rifle at all. However I am at a loss for what could be causing this. I don’t have any spare parts besides a bullet guide which I can swap out. I thought it might be the clip latch pin but I doubt it, because whenever a clip is not inserted and the bolt closed, it will not bind like it will when I’m actually trying to eject a clip. Further, whenever I look inside the action while trying to press it, the little catch on the clip latch will just barely move.
Before anyone says clip latch spring, that is not it. It also happens whether the gun is in the stock or not.
Does anyone have any advice on how to fix this? Should I just keep shooting it until I’m able to press it all the way in?
Thank you so much for any help you can provide

Trigger guard won't close
Another person that can't get the trigger guard to close on a new wood frame CMP. Read all I can find and can get it about a quarter inch with all my might but not enough still. Hit it with a hammer and it didn't budge.
Hammer is back, it closes easily to just the receiver when outside the stock, the rear of the housing does make some serious indentations when I use force.
At a loss.

Running out of stuff to do.
I guess I’m getting caught up on things to do on my old milsurp stuff.
Yesterday I cleaned some of the nastier leather slings with saddle soap and treated most of them with mink oil.
Finishing mink oil on the rest of them today.
Time to find another project rifle I suppose? 🤣

White painted band on ‘42 SA. Any thoughts?
Recently picked up this beauty. It looks to be a matching '42 from what I could see. I don't have a gauge set at the house, but she shot like a dream today. Does anyone have any idea what the white band could be? I was thinking it could be a unit armory mark.
Any information about what I have is appreciated!

M1 carbine rear sight help
Hello,
I got this m1 carbine. Replaced cracked front sight all springs and swapped the extractor. Shot 50 rounds through her and the POI kept changing thought I had to drift the rear sight when I got home. The rear sight ended up coming out by hand. Ended up getting a replacement stamped rear sight. Using the rear sight tool I pushed it back on. The issue is the staking done to the previous sight looks to be drilled out on the receiver and the replacement sight itself. gun is non import marked so who knows what happened post refurb. I plan on staking it again with a pointed 1/8th punch but wanted to confirm with the larger community of what the cmp has done on your rifles and if anyone encountered this before.

Can anyone identify where and when this en bloc clip was manufactured?
Appears to be marked "LX" on the bottom. Internet searching has yielded nothing so far, hoping maybe the group can figure this out.

First time shooting M1 Garand
I just picked up my expert grade reclaimed M1 Garand from the CMP yesterday. Today I put 80 rounds of 30-06 through it. It's probably the most fun gun I have now (and I have a PS90). It is also the first time that I've bruised my shoulder from shooting. lmao

Need help identifying plug.
I know it’s schuster plug, looks like a m1 garand high volume gas plug. I’m asking this because my parents bought me this years ago and I was told it was adjustable. They had my gunsmith uncle put it on and he said he couldn’t adjust it when he installed it, but I was young and the gun worked. Now I need to reinstall my plug after I had to install a new stock. So what kind of plug is this?

Gun show drama
So I was at this gun show this past weekend and there was this guy who I've seen at the local shows who basically always has rusted outs POS and asks gold level prices. But he had himself a CMP Springfield M1 nothing fancy about its asking 2K. I was standing there and I heard him say to another guy "it's all numbers matching". After the other guy left, I asked him what he meant by it's all numbers matching and he's like all the numbers are the same. I asked which numbers and he started to just point to random spots on the with numbers. I said let me let you in on something and I told him numbers matching is for like german lugers and and such where the pieces are marked to match the serial. The US doesn't do that it has a serial a date on the barrel but the numbers aren't connected. He got so pissed that he yelled at me to leave his table and not even loo, at his stuff. I can't help it if you try to scum people and won't even listen to people when you know your in the wrong. Why can't these people just try to get better? *Pictured is my WW2 Springfield and Korea Era H&R*

Fav Range Ammo?
Since I've been getting PMC X-Tac NATO at a decent price for my M1A, I've been rolling with that but curious what others have found. I've made the decision that if I'm plinking, it's NATO and I'll save my 308 for the Purge.

Questions about CMP
I'm starting the process of purchasing a M1 through the CMP, I'm wanting to know if there's a time limit on long you can wait to purchase after your application is approved?

CMP Surprised me
I finally bit the bullet(pun intended) and order an Expert Grade last week. I was fully expecting that I'd be waiting 3-4 days from submission to getting a payment link, and then 2-5 weeks before I received it based on everything I had read.
I submitted Wednesday morning, had a payment link by noon, a ship notice by Thursday, and received the M1 Garand by Friday Afternoon. I was totally not expecting that, but not objecting in the slightest :-)

r/M1Rifles • u/EchoNineThree • 7d ago
So this just happened! 18 years in the making. Our good friend Gio from AMD65 Tech painted this M1 Carbine stock for me in 2007. Then in 2014, we built an M1 Carbine pistol on a virgin Springfield Armory receiver. Now, a winning combination!

Contacting cmp
So I wanted to calm down about it before asking. Got my first m1 garand from the cmp last month and had a bad time with fedex. Basically had to drive an hour to pick it up from the hub because they were too lazy to deliver. But in the process I got told I couldn’t schedule a pick up time because I wasn’t the sender. Made no sense but ok, I tried for two days to get through to cmp but only ever got an answering machine. Anyone else have this experience with contacting them?

Garand disassembly/cleaning advice
My family has made the mistake of leaving me unsupervised… I plan to take advantage of this time by cleaning all of my rifles. I took the maintenance class offered by the CMP at the national matches, and they said that the bolts stay married to the receiver. Are there any other parts that would not be completely interchangeable in between the garands? I do not care about parts matching all of them are Mix-Masters from the CMP. I will be using an ultrasonic cleaner for cleaning small parts in batches any advice on any topics regarding this would be appreciated.
Edit: any recommendation for a good cleaning solution safe for parkerizing in an ultrasonic cleaner. I was just going to use hot water and dish soap. Then wiped with thin coat of oil. reassembled lubed and stored

Just inherited enough .30-06 to take back France from the Germans a third time
Middle stack in the brown boxes is all Lake City surplus 30-06. About 2k rounds total, including a .50 cal can full of loose rounds and a bunch of reusable brass.
Also got an H&R Garand and a pre-64 Winchester Model 70.
Thank you Grandpa 🫡
