Weird barrel hum throwing of your groove or maybe some invisible ding .
Between 2&4:00 is where the Armalite action is supposed to eject . If it's not dinging cases your golden as long as it holds open on the hold open not the mag follower .
When you shortened the barrel you removed part of the gas dwell time and ultimately lowered the the port peak pressure and or volume .
It's nice when a simple adjustment to the mechanics fixes the flow you've wrestled with so long .
