Alabama, can you specify more on what you're asking?
Utopia,
I have read some on this being the cause.
I think what I'm going to do is try turning off the gas flow via the adjustable block, and double check that these cases aren't being marred by pressure.
Secondly I am going to fire some of these hot loads in my other AR, using the suspect BCG (swapping BCG's), and using the other BCG.
If the suspect BCG still has problems I am going to remove the oring and see what happens.
