@wiguy the gas should be in the full open position out of the box, if the screw on the front of the block is flush, it is. Check the gas key on the bolt carrier, as I noted above, mine was not properly attached and loosened after a few rounds and caused cycling issues.
If you find yours has done the same, clean and de-grease the screws, key and carrier with non-chlorinated brake parts cleaner. Then put a light coat of high strength red loctite or other brand thread locker on the bottom of the key to act as a seal (Permatex gasket sealer can be used as well). Put some of the red loctite on the screws and torque to 56 inch pounds and let cure over night. Failing that contact PSA for an RMA if you don't mind the wait.
