Failure to go into battery

[ecosystem3]

As a followup, I had the rifle out this weekend and it ran like a champ. I removed the extractor o-ring and there were no more jammed BCGs going into battery. I put 60 rounds through the barrel and was eventually shooting MOA.

While debugging, I did try to slide the BCG into battery without the firing pin and a few times the cam pin did rotate and lock the bolt. After some praying and jiggling, I was able to remove the BCG. A spare firing pin has been ordered.

Again, thank you all for your input and guidance!
