Hello. I changed the hammer and trigger springs on my M3K. It is the first time that I remove the trigger group and change parts on it. The carrier now gets stuck in the up position (leaving the loading port open).
If the bolt locks back, the bolt release won’t release the bolt - I have to move the handle forward so that the bolt can chamber a round (dummy).
I have removed and reinstalled the trigger group several times now and I am still having these problems. Any suggestions?
