Need help from the brain trust here

So I have assembled a handful of AR’s over the years, but never really had to trouble shoot one before. A coworker of mine asked me to look at his AR that won’t eject. I took it to the club today and it won’t eject at all. I changed out the BCG and mag for the one out of my AR I had with me that works fine, still no dice.

Now, it is a DPMS rifle. I know they’re junk, but I used to have one that ran fine. Any ideas? Thanks in advance for any advice.

Will it extract and then fail to eject? Could use a little more info to help.

After each shot. The BCG would be in the forward position. When I racked the BCG the empty would come out and when I let the BCG go forward it would load another round. It’s a single shot right now.

I forgot to add that I also changed out the recoil spring and buffer, didn’t help.
Also the chamber is clean.

Headspace issue maybe?

If the bolt isn't moving during the firing sequence it sounds like a gas issue. Has it ever worked? I mean, sounds crazy but maybe the gas port wasn't drilled in the barrel or something dumb like that.
