just picked up winchester

I know next to nothing about the m1 carbine. I just wanted one. I picked up a CMP winchester sn 5751xxx. The stock is a winchester. I can see most of the cross cannons and I think the initials WRA over GHD (not boxed).

One questions I have is that it has a Underwood barrel Rough (the barrel is not smooth) I can see the flaming cannonball and -44 just behind the front sight? No month stamp? Was this common? Did winchester use Underwood barrels? The SN put manufacturing sometime in 44.

I know it is a mix master, I have a inland trigger group, Rock ola charging handle/slide box. Bolt is winchester.

Took it out this weekend and love it. I did have one stovepipe and one jam (loading) But still real happy Looks great next to my garand.:dancingbanana:

Thanks I sure more questions will come up as I dive in and really look at things.

Welcome to the forum, yes undated barrels were used and cross manufacturers happened. Also during time they were overhauled and a barrel would be replaced without concern as to maker.

There'll be a few along shortly that will help you consume your carbine...

Welcome to the forum. As Jim said, many will comment on your carbine. If you have and can post pictures, it would help.

Guys here like to help and have a great knowledge base.

Jim

You have a typical post war rebuilt Winchester. As the guys said it's not unusual for these carbines when updated to the last version to have had parts mixed. The barrel is a replacement as both Underwood and Winchester both made all their own barrels. Your serial number dates to about September 1944. Having a carbine is a great rifle to shoot and enjoy.

In Winchesters serial number block- 5,549,922 to 5,834,618 some of their Receivers were made by Underwood, and were marked T or AW below the serial number, often on the rear tang..... forward of the recoil plate.

"One questions I have is that it has a Underwood barrel Rough (the barrel is not smooth)"

The outside of the Underwood barrel has raised milling grooves from when being turning, common on all Underwood barrels.

Sometimes a worn die stamp left a light or nearly missing month stamp, or part of the year date.... So yes fairly common.

During WWII production Winchester DID NOT use Underwood barrels.
A Underwood barrel found on a WRA would have been a replacement barrel.

Underwood stopped making carbines in April of 44 (4-44) but did continue to build and supply replacement barrels as a sub contractor and was 1 of 2 Prime carbine makers to get a post WWII rebuild contract, their rebuild mark was stamped usually on the left side of the stock... looking like this: .U.

Any Underwood barrel dated past 4-44 was a replacement barrel.

Look closely for a Month Date stamp.
Look for any type of rebuild stamp on your Winchester stock..... Like RIA over EB in a box, or AA, AN, BA, MR, OG, RA, RRA, RIA, SAA, SA..... etc.

Sounds like you've run across a CMP rebuilt Carbine.
Enjoy it and take some pictures.

Welcome to Milsurps....

P.S. I have a WRA 5,811,227 Serial number was stamped Oct 10 1944, probably completed by the end of Oct.

Thanks for the replies.
Stock only has wra, GHD and cross cannons Nothing else.

One other thing. My brass flies out the the front right.I would say a 40 to 45 degree angle. I want to collect my brass but where I shoot you can not go in front of the shooting line at any time. Is my brass going too far forward. I cant get any of it. In videos I watch most fling the grassat about an 70 to 80 deg close to an ar 15 which I can collect the brass. Ejector worn? Or nature of the beast?

Something like this:
https://www.milsurps.com/attachment....47&cid=1&stc=1

I see the rear sight has been pushed off-center to the left. I have three carbines and every one of them require the windage to be adjusted far left on the sight to obtain correct POI. I wonder if someone was anal enough for this to bug them and pushed the sight over so the elevator could be aligned in the center of the sight? I've not seen as many carbines as most other members here have, but I've not seen a rear sight pushed that far over. This is not a dig....just an observation.

I have an Inland that I aligned the rear sight on. It was way off. Just thought you should have equal windage adjustment in both directions. When the adjustable sights were installed as upgrades, the military manuals showed gauges that were to be used to keep the same windage (with new sight set to the index mark) as the original leaf sight provided . Welcome to the forum! - Bob

would it be wrong to have the rear adjustable sight off and put the older flip up sight on it? I just like the look better.

Do you have a Bolt Tool?

Have one on the way. Don't have a sight tool. Would look for someone local that could do it

To change the rear sight to a type 1 flip sight may very well bring your carbine back into alignment. Front sights were adjusted to the flip sights and when replaced with an adjustable rear sight the front sights were not replaced so they are off sometimes quite a bit.

I've had good luck with Matrix carbine tools:
https://www.matrixprecisionparts.com/m1-carbine-tools/

Thinking about your Ejection @45* may be a bound Ejector and Spring.... or worn out tip on it.
Extractor may have a chip or burr under the lip.
Stem plunger and spring could be bound up a bit with crud.
Either way a Bolt Tool is a must IMHO to break down, service/clean and re install.

Some will also call for a new Op Slide Main Spring.

I believe as long as you know you have a clean chamber, most times it's the Ejectors tip gone bad. Needing a upgrade to a newer/better style. Or chipped/burr under Extractor lip (can be lightly filed)
Late Op Slides can also help..... but I'll stop here.

P.S, Make sure you can push the tip of the Ejector in, and feel the spring push back out as you back off. Macro pic of bolt face would help.

PSS Good link here about Ejectors Etc..........(read All)......
Carbine Skips Brass Off My Head - CMP Forums

Replaced all bolt springs and ejector with new parts. Also, put a type 5 Winchester slide in it. Took it out today and Shot about 250 Rounds. I could not stop. All i took with me. Should have taken more. 1/2 of the rounds were reloads. 1st attempt at 30 carbine. I was very happy with the results. I did have one round Stovepipe. Not quite a stovepipe but close. It did jam. It was a reload.

At 50 yards hitting target ok. Then went to 100 yards. Could not hit target. Figured out I was hitting Hi. So I aimed for bottom of target and hit the top. Took about 20 rounds to figure out. So I finally got out my reading glasses and looked at the rear sight. I thought I put it all the way forward but it still 1.5 clicks left. So I moved it all the way down (Froward) I believe the 100 yard marker and started to hit target at aim point.

My brass problem was fixed also, I got almost all my brass back. It hit consistently at about 4:00 position. Put my range bag there and it got at least 1/2 in the opening. The rest I had to pick up.

Thanks to everyone that helped. This is a great gun and what a blast to shoot.

Glad we could be of assistance...

Excellent!!!!!!!!!!!!!!!

One thing with replacing the rear sight with a flip: Your adjustable sight was staked down and those stake marks are usually well defined, so you will see them and that is fine if you are not passing it off as being original to the gun but just for your own pleasure. I have replaced several of my sights with flips as I prefer them and I like the look and the serial number and maker ID is much easier. I was lucky, most of mine had very shallow stake marks to none at all.

If I replace the rear sight it will be just for me. I am not a collector, I just want to shoot the thing. I like the look of the type 1 flip sight. Also would be nice to see the winchester on receiver. now I can just make out the W and R that is it.For all I know it is a W R Receiver. It did come with CMP Cert and the sn matches the Cert.

I think sn put it with a type 2 sight.

The guide tool would locate the new rear sight in the same windage position as the old sight, but that's no guarantee the old one was right to start with. After the sight replacement, a carbine would have to be targeted before being finalized. The aperture would be centered and the carbine fired with the base not completely staked but stabile enough to shoot. Then the base may be shifted to correct targeting and finish-staked. It is of no concern if its off to one side or the other as long as its on target. When you encounter a rear sight that requires the aperture to be cranked way over to one side, it means the carbine has not been properly targeted since the sight was installed, which in turn could mean that it was done outside the military or in a foreign country. It could mean other things too, like the barrel was changed, the barrel is bent or the front sight is a little canted. So, when you see a sight like that you know there are some things to check out on that carbine.

PS I-44 is spot on. Were me? Once correctly positioned and shooting straight, I wouldn't restake. A drop of Blue loc-tite will work.

Ya thanks. Net was with me just incase. But will be left at home in future

Still debating about sight. National gun show in September in ky. That is the only show I I can get m1 garand or car one parts so I have a little while to decide. Also may look for type 5 trigger housing. Try to get major componets to Winchester just for fun and back up parts

I have a 5.6 Winchester that is thought to be original. In the 5.6 run the rear sights could be either a type 1 flip or a type3 adjustable. I would think that by the 5.7 run they were all adjustable sights? You might be looking at the original factory rear sight?

I have three carbines two are original (a 5.6 Win and a 5.4 Inland) as built. all have the adjustable rear sights. All of these sights are centered on the receiver and all shoot exactly to point of aim at 100 yds. The one that is most accurate is my NPM with original IBM Corp barrel and added type 2 rear sight. Before I started taking things off or knocking sights from side to side, I'd check the barrel index and the barrel for straightness. My point is that the upgrades done to these weapons should be looked at as improvements and they should be somewhat centered. That is a very cool looking beautifully patinaed carbine. I'd be very reluctant to change anything except what it takes to make it shoot straight.
