Just confirming, you are running .223 ammo WITH a .223 bolt. I did that recently. I put my 6.8 bolt in the bolt carrier and inserted it in my .223 AR. It would push the round into the chamber but obviously, it would not extract. The case just laid there inside of the chamber or on top of the magazine. I had this stupid look on my face for several minutes until I looked at the bolt face. Duhh!! I had to drive all the way home and get the right bolt and then back to the range. 10 short miles round trip.
Anyway, check the bolt face to make sure you have the right bolt.
