M1 Carbine failure to eject issues: Possible fixes?

[Iknownot]

So, what causes a M1 Carbine to stove pipe? (Bolt closed on ejected round which is stuck and won't let the next round chamber).

It does it with different magazines, so I don't think it is a magazine issue.

I've replaced the recoil spring with a new one. What else should I look at?

Thanks for the help

ejector spring.... also remember.. oil not grease for Carbines...

That's interesting, as I was specifically told grease, not oil, for Garands. Is there that big a difference?

When was the last time it got cleaned? Make sure your gas piston isn't gummy.

Are you using soft point ammo? My USGI carbines generally despise it.

I had a similar issue, and replacing the ejector spring fixed the problem. Ammo may also be an problem. I've heard that Wolf .30 carbine ammo is 'weak', and that may not cycle the bolt completely. I use Aguila, and have never had any problems once I replaced the springs.

yup.. big difference.. the M1 Carbine has a light action and grease will slow things down considerably. The only grease I use is inside the slide where the bolt lug sits and just a slight dab on the small left lug.. other than that oil on everywhere else.

I was having problems both with stovepiping, and with failure to go completely into battery. liberal oiling solved both problems. I have noticed that at least with my carbine, stovepiping is more likely to be at least magazine related.

It's been cleaned well, so I don't think that's the issue.

I made sure it was properly oiled this time around and the stove pipes still happened.

I'll try the ejector spring and see if that makes the problem go away.

are you using wolf?

what ammo are you using

[Iknownot]

Aguila, but it did it with remington in the past as well.

I've actually had good results with grease on the carbine- but I don't slog it on- a thinly finger-wiped layer worked well. Tested w/ armscor and S&B ammo.

What would cause stovepipe on an unfired cartridge? ie, cycles and extracts fine, but failure to chamber?

Carbine is greased fine. Not too much, not too little. Piston's cleaned and is fine.

I also had short cycle or stovepipes and it was that my gas piston cyclinder was lose , it takes a special wrench . I lost some hair trying to figure it out. Order a gas wrench either way as they are needed for cleaning and reassembly .

good luck
