M1 carbine problems

[Al Thompson]

Hi folks,

Have an Inland carbine that's popping the extractor and ejector when it's fired. Thought it was the ammo at first, now it seems that something else is to blame. First time it occured it was on the third round fired, this tie on the first.

New bolt? Thoughts? Suggestions?

Something is unseating the extractor. The extractor is held in place by the spring-loaded plunger that rides in a notch on the extractor. Remove the bolt and check the bolt's bottom surface to see that the extractor's "tail" is flush or slightly below flush. If the "tail" is not flush, the extractor can be unseated as the bolt rides over the next cartridge in the magazine.

Also check the extractor and the spring and plunger for damage.
Look for a broken or chipped "lip" on the extractor where the plunger holds it in place.

I've seen a few carbine extractors and plungers damaged by attempts to disassemble it by "punching" out the extractor like with the M1 Garand. If the extractor is punched out the small lip can be broken.
If the ejector or plunger/spring is damaged the extractor can do just what yours is doing.

Although the carbine bolt CAN be disassembled without the bolt tool, it's MUCH easier to use the tool, and there's little chance of damaging anything

Thanks, I'll pull it apart in the morning. I have a great Rock-Ola that should give me a good template.
