Will be interesting to see what the problem turns out to be.
A couple of summers ago I was out shooting and a young fella showed up at the range and he had just bought a new Aero Precision, assembled from the factory, upper. The upper was brand new and had never been fired.
It would only shoot one shot like a single shot and would not eject the fired case. The bolt would not even move rearward when it was fired. It acted like it was not getting any gas. He had to force the case out by hand using a lot of force. It would load the cartridge from a magazine and go into battery just fine and it would fire the round just not eject it.
We did check the gas block and the tube and they were good to go and I asked him if he had installed anything new on the rifle. He said that he had put a new modular style trigger in the night before so I looked at it and found that the 2 tightening screws at the back of the housing had never been tightened or had come loose. I am guessing that they were never tightened and those screws stick up quite a bit above the trigger housing when they are most of the way screwed out. The trigger was pinned but was loose enough to stop the bcg from moving or those 2 screws sticking up were messing with it. We tightened the screws and everything started working correctly again. Shot real good after that.
Just my .02.
