I just bought a new-to-me M1icon, and I have run into a problem. I have greased all the recommended points, and checked the rifle to the best of my ability. But here is the issue;

I can feed single rounds into the chamber, and they eject flawlessly.

If I put in a loaded enbloc clip (I tried 7 rounds too, just to make sure) it will not eject the fired case. Although sometimes it will, but 9 out of 10 times it won't.

I *think* the problem is the operating rod spring, but I am not certain. To put an enbloc clip into the magazine takes a lot of effort on my part...


I'm sure someone has run into a problem like this before.


Thanks in advance.
