Diagnose this Malfunction, Redux
Ran fine for a long time. Now, it has just mysteriously become a single shot. In the videos above, you will see some times the casing is halfway extracted. Those are times that the gun is not braced. When it half extracts, it was braced against my chest.
I have given it a good cleaning, ran the bolt both wet and dry. The only thing I can think of is it somehow being undergassed. But how does that happen just all-of-a-sudden?
