Contradictory Issues?
#6
One observation this morning I did not think of last nite: your ejection pattern , 4-5 o'clock, appears under gassed. These steps all work towards upgrading your gas-flow volume/pressure.

1. Are you using a rifle buttstock or carbine? I have not had any luck, really, with rifle length buttstocks. Can you swap lowers or swap in a carbine stock, check for improvement.

2. With that carbine stock, swap out the JP SCS for a standard carbine spring and standard, 2.8-3 oz buffer weight.

3. There is a possibility that you are losing too much gas via leakage in/around the bolt carrier, what kind is it. See if swapping in a different carrier (keep the monster bolt) changes anything.

4. Not trying to say definitively that this is the issue, but about a year ago I had a similar problem (except for the dings on the neck, that is from hitting the deflector as described above) of gas even when full open, in a 223 wylde barrel from Ballistic advantage. Nothing worked until I opened up the gas port diameter (there are easy ways to do it and not mark or score the rifling on the bottom of the channel) like the accurate shooter thread (don't believe I had seen this thread but something similar). I got a set of "wire diameter drill bits" and gradually opened it up until it cycled properly. Now BA is not a Criterion but is a decent barrel, and other BA's I've had did not have this problem.
