    I received and installed a new adjustable gas block from Clint with the .060 insert a few weeks ago and did manage a quick 20 rounds suppressed yesterday at the range. I reverted no other parts and the gas issue was nearly non-existent and the rifle cycled fine. I will continue to experiment with buffers and springs and different gas inserts to see if I can dial it in a bit tighter. I'm guessing it will run without a can based on my brass pattern but I will test this definitively when I have more time.
