Talked to Dave (Armalite gunsmith) today and apparently there are approx 100 Eagle Arms 24" match barrels out there with an undersized gas port.
These have a gas port dimension of .078 (5/64") and should be .084
My rifle was short cycling and I was able to narrow it down to the gas port sizing.
Two options...drill out the port yourself (which is what I did) or send it back to Armalite. It's really an easy fix.
I used a #45 (.082) numbered drill and now the rifle functions flawlessly!
