I have worked on lots of Carbines (M-1 and some M-2), and always got the ones I carried as LEO trunk weapons running 100%. What is it doing specifically? Need more data.

Some things to check:

1) Recoil spring should be 10 1/4" or very close,
2) make sure extractor has no chips and spring has sufficient tension and free play
3) make sure ejector moves freely and has sufficient tension
4) make sure trigger housing is not to loose, or magazine too loose in trigger housing
5) chamber an empty case and smartly work action to check ejection -optimum is that it kicks it at least several feet. If it barely clears the receiver, there is an issue.
6) make sure slide moves freely and make sure recoil spring guide is not bent.
7) Make sure magazine springs are oriented correctly: Long side to rear /\/\/\/\/\/\/\ bottom being rear.
8) Make sure gas piston is loose in the retainer and has full range of motion. Check for excessive carbon build up.

It fails to feed...Always on the right side...The soft points deforms and the ball will continue to feed if I bump the operating rod. I have taken the trigger housing and pin from the carbine that works and it still fails to feed....There is sloppiness in the trigger housing/mag fit...The pin also seems sloppy..The hole more than anything may be enlarged....How that could happen, I do not know......I'm going to put this thing in a couple gallons of gas or MEK..if that does not help ,then send it somewhere, ....Charlie

You can try and take the trigger housing off your good carbine and try it on your bad one. If it works OK then you have narrowed down the problem. Are you using factory or reloaded ammo? Check the magazine release for wear and also the nubs on your magazines which might work with one but not so well with the other if slightly worn. If the magazine release is worn replace it with a new type 4. As stated above check the bolt making sure the extractor is clean and free moving and the same with the ejector.

Can't see if they run a gunsmith shop....Charlie

How much slop is there in the front pin? Try the front pin from the other carbine. I got one that had a non-standard, undersized pin. If the hole in the receiver has been hogged out, you may need to resort to an oversized pin. Clamp the receiver and trigger guard in a vise and drill the hole to match. This is extreme, but I have seen it done. Also a rear lug being excessively loose can cause a problem. I do suspect it is an issue of trigger guard looseness causing the problem.

Don't burn it. It's worth something, even as a wall hangar. Or for the parts.

I have one I'm frustrated with too, but am working on it. Well, it's sitting in parts right now. Mine's not quite as bad as all that though. It feeds most of the time. But every range session I've gotten a few on up to several malfs.

You got any pics????

Is there any difference in the finish (e.g. "roughness") of the bad gun's feed ramp versus that of the good gun? A toothpick makes a good "feeler" if you can't eyeball it. In order for the soft point to get damaged, it must be hitting or scraping against SOMETHING

One carbine I was trying to diagnose, I removed the action from the stock, took the hammer out (since I did ot haveing dummy proving rounds) and cycled it by hand doing a visual. I tweeked the magazine from one side to the other and back and forth as I cycled to replicate the malfunction. Just a thought.
