Great thread and thank you. I am having the same problem. BCG is not loading the next round. I have a STAG 22" barrel on Aero parts and Odin gas block. 

 

What was the conclusion on everything here? From what I gathered:

1) The buffer spring was  replaced with a weaker one, but that was only compensating for the undergas problem

2) the OP drilled out the barrel gas hole to .100, up from about .093.to 095 -Optimal for adjustable gas block, negates the need  for the spring replaced in item 1 above. 

3) Armalite gas tube was used which is a bit longer than a DPMS ? 

4) Ejector problems, OP polished the parts and fixed that problem

I will recommend that you start a thread dedicated to your rifle. It makes sure that we are only talking about your rifle. There will be questions about your rifle and its configuration.  Not all problems that seem similar have the same correction.

Please read this thread to see what kind of info will be asked.

Today was my first day shooting my AR10 build. 

It was not cycling/ejecting the rounds.
