Post the lot number on the ammo. Also do a COAL measurement on an unfired round.
Unlikely, but measure the bolt overall length, and bolt face depth to see if it is a .125 or .136.
With the gas block in position (your post reads like you tried to move it) - remove the BCG and look to see if your gas tube is centered inside the receiver, and you have the correct end of the gas tube in the receiver. Inspect your gas key on the BCG to see if there are nicks or deep markings on it.
And stop prying open your action. Google "AR15 Malfunction Clearing", and "AR15 Mortaring" and learn how to do it. Two handed pull on the charging handle first, then Mortar if you still can't get it to release.
