Check the gas block hasn't slipped right or left from it's long since mounted postion.
Your gas key could be dragging on the gas tube.
Probably not the issue but you never know till you check it.
Also get you a good foaming bore cleaner and mount a ar15 chamber brush into a cordless drill and while the foam is doing its job on the chamber, work the crude out of it, repeat several times to be sure everything has been broke up and then clean it out very good and see if the condition continues.
