Gentlemen
I have recently built my 2nd AR.
20" heavy barrel,Auto BCG and blackhawk 6 pos stock.
Now.......I test fired it today with some Tula.
first 2 shots ok.
After that......it was a one shot wonder machine.
Checked gas block alignment and it is good.
Also......it was not ejecting everytime and forward assist was used once or twice.
QUESTION:
Too light a buffer?
Too heavy a spring?
Auto BCG too heavy for Tula ammo??
Suggestions please.
