Ended up having to tap the gas block with a brass hammer tight to the barrel shoulder, tweaked the gas tube so there was minimal contact with the gas key. thinking the main issue is cheap gas block and tube, will be ordering a new gas set up
You said it was a used upper could the gas tube be fouled/blocked? Just a thought? I troubled shot a friends upper who had similar situation i had to align the gas block and put in a carbine spring and buffer to get it to run 100%
