Hi all,

Hoping someone has experience with an issue and can point me in the right direction. I have a problem with an M1icon carbine that seems like the sear won't catch the hammer half the time. When at the range, most of the time the rifle functioned fine. But, sometimes it would chamber a live round and the trigger was dead. I'd eject the round, chamber a new round, and then it would resume working fine. It seemed to work better if the barrel was more vertical when pulling the slide back.

I took it apart at home and saw that the hammer would just follow the bolt home instead of locking back into place. So I cleaned everything up, reassembled, and the problem persisted.

Here's what it looks like:


I then ordered the Wolff M1 Carbine rifle service spring pak and replaced the sear spring and the operating rod spring. But, it seems like the hammer is still just a millimeter or two from locking back into place.

Any tips?

Thanks!
