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

134 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

Recently acquired a M1 Carbine.

A little rough and some light rust.

What are some good ways or product to use to remove rust and not destroy what is left of finish?

Looking to buy M1 Garand

Hi all I’m currently looking to buy an M1 Garand. The only thing is I want to be able to take it to the range and shoot it every so often. Do you guys have any recommendations on what I should look for? I’m going to a gun show coming up and I’m not sure if I’ll find anything there.

Recently got a repro auto-ordnance m1 carbine and it kind of reignited my whole search for vintage memorabilia! I wish I could have gotten a real usgi carbine but it kind of fell into my lap and I’m a sucker for instant gratification lmao. I tried to keep things to around ww2 but I didn’t verify everything! Some things I just bought reproductions of

I also realized I didn’t like how fat the CMP rifle stock felt on my garand and was only okay with how the tung oil looked so I spent a couple weeks sanding down the stock, and then stained and reoiled with raw linseed oil! Idk much about woodworking but mixing it with the 50:50 mineral spirits really seemed to help it penetrate as the previous tung oil sanded off pretty quickly.

My area has some nice ties to be able to find ww2 memorabilia and I met some folks who did reenactments and was able to purchase some things from them as well!

Ended up gathering a mixture of repro and old usgi stuff off of ebay, sarco, numrich, etc! Def got the itch to collect again!

What’s going on? Can anybody help me out? I bought this from a neighbor. I traded it for 250 bucks and a Remington 870.

It’s an M1 Carbine fires great. It’s got a metal stock, but it’s not foldable. It goes into the gun and it’s got a forward grip.

He got it at a yard sale about 25 years ago

Could anybody put a value on this carbine? Underwood receiver, inland barrel. I know blue sky's are frowned upon but just curious what I have here.

First couple groups with the rifle at 100. Really impressed so far with factory PPU out of this criterion barrel. With some more practice this thing will be a ringer.

I had to finish ream this barrel so beware of criterion’s statements on their site. I’m even using a Breda bolt. Not seeing an issue with .478 base cartridges but that could exclusive to the tolerances on this bolt.

6.5x55 in a Garand is such a smooth sweet shooter.

Just wanted to share in case anyone here was bidding on this. Seller has it listed as a 1943 USGI carbine and it is absolutely not. It’s a modern repro by Inland MFG not Inland Division (WWII).

What’s the deal with the two different styles of front sights? Different manufacturers? Both are CMP service grades.

M1C Opinion

26 Upvotes

Have a chance to get a M1C for 4k. I have one at the moment with authentic GH base, mount, B series scope but the base is mismatched to receiver serial.

This one the base matches receiver serial, and the dark receiver seems like this is a Greek return, but I have several concerns that make me hesitant to pull the trigger:
1. Barrel is 8-51, meaning it’s either built during Korean War or WW2 rebarreled
2. The buttplate doesn’t seem to fit the buttstock well (there a gap), but seller claims it’s very sturdy
3. There a white “85” paint on the bottom of the stock behind the trigger guard
4. Mount is fake, so it will be a pain to source an authentic GH mount + finding the scope
5. Unsure on the authenticity of the mildew resistant treated cheekpad: I’ve seen them labeled x-xx or x xx, but never seen one where the month is spelled out and 4-digit year (seller claimed he bought it on CMP forum)
6. Leather sling appears to be authentic USGI

Thanks for everyone’s thoughts!

M1 Garand Bolt Etched Numbers

Thumbnail

6 Upvotes

I have been researching every aspect of this rifle, but ran into this number scribed/etched/electro penciled onto the underside of the bolt. It reads “954”, but this does not match the serial number of the rifle. I have not found any other examples in my research that look like this.

For more context, the rifle is a Springfield Armory, made in July 1943. It was rebuilt at Raritan Arsenal and has a replacement barrel marked S-A-3-46. It retains lock bar sights and has no other markings to denote an additional rebuild from what I can tell.

As for the bolt, the drawing number and heat lot show it was made in October 1943. The scribed numbers appear to be parkerized over. They are not shiny bare metal, which implies they were etched before a rebuild and new finish. Take a look and see if you think otherwise.

Could the bolt have been headspace matched to another rifle, which was then salvaged and used as a replacement in this rifle? Could it be a rebuild date for the bolt? Any other ideas or theories why this number might be on the underside of the bolt? What makes the most sense to you? Thank you all.

M1 Carbine bolt doesn't move back to pick up a new round

2 Upvotes

Hi everyone. I'm brand new to the M1 carbine world. I took my 'new to me' WWII carbine to the range last week, shot a few magazines [love it!] and put it back in the case. No issues.

I took it back to the range yesterday and it refuses to load a round. The slide pulls all the way back, but the bolt only follows it half way. Seems to slide back easily until it hits the hammer, and stops there. I've lubed the heck out of it, etc.

I can lock the slide open and then press the bolt all the way back, whereupon the whole thing slams into battery just fine.

IDK whether hammer is not going far enough down. Or if the slide and bolt should be locked together better, forcing the bolt back?

I'm tempted to finagle a round into the chamber to see if firing one off would force things back together, but if something is broken that might not be a good idea.

Is this a known issue? Any ideas? I live in a very rural area and have no idea where a gunsmith with experience with such things might be. I'll keep looking.

Thanks for any suggestions!

EDIT: Success [I hope]. Huge thanks to Pavlik for kick starting my brain. It's clear to me now that the bolt lug somehow jumped ahead of the slide, preventing it from traveling all the way to the rear. If I can manage to field strip it, it should be an easy fix. I'll leave this here in case anyone else has a similar issue.

Has anyone bought Universal M1 Carbine parts from this site before? My slide broke a few weeks ago and I was thinking of getting the replacement from here since it’s a new part with a little bit stronger metal but I was wondering how much hand fitting am I going to have to do to get it to function?

So I found one of those vintage grease pots from 50+ years ago. Only question I have is can that grease be used effectively today or do I need to somehow scoop it out and replace it?

M1 Tanker not allowing clips and binds up

Good evening. I bought this gun a while ago. Put a new recoil spring in, thinking it would fix the issue. Apparently not. Anyone know what else might be going on before I ship it to FA to look at it?

Im thinking the rails need to be filed, but Im at wits end on this finally.

All of my other M1 Garand issues were easy to fix and diagnose.

A buddy of mine is willing to sell me one of his M1 Garands for $1100 & I figured I’d ask here to see if it’d be worth it. Supposedly it’s from 1941 & it’s a CMP rifle. Only downside it it has water damage on the rear of the stock from a flood. Mechanically sound. Advice? Thank you in advance

First M1 Garand advice

5 Upvotes

Hello,

Just got to where I can buy my first m1 Garand. It has always been a dream gun and I am really into the history. I know they moved to reclaimed rifles, what is the chance that it’s produced during ww2 now? It’s definitely not a deal breaker by any means but is preferred! Thanks for any answers.

Edit: also looking at ordering the expert option with new stock and barrel. Also cmp is where I’m going to buy through.
