Where things currently stand: pull back the handle...insert loaded PMAG...release...fire AR...ejects just fine...but next round gets caught semi-sideways by the BCG and doesn't get chambered

I have not read every post in this thread, but your problem is interesting for sure.
Here's a couple of questions to verify:
1. Does it always lock back on the last round using 5.56 ammo only?
2. Do the problems happen on 223 ammo?
3. How much lube do you have on the BCG, and how many total round count on the rifle now?
4. Have you tried duplicating the issue with another BCG like the Spikes?

Try this again and see if you can isolate the issue:
1. Use only factory loaded 5.56NATO ammo for each test.
2. Use a new magazine preferably a Pmag or any mag that is known to be reliable.
3. Do the one-round in the mag test for at least 10x to see if it locks back every time.
4. Then load 2rounds in the mag and see if it still works or does not feed on 5.56 ammo. If you get FTF's, then you are definitely shortstroking from the upper.
5. Check that the gas block and gas tube is tight and not working itself loose.
My only other thoughts is that it could be your BCG. What exactly is the BCG and what brand??
