LR1955 gives a good process to follow.
I've seen similar issues and they were always related to the extractor holding the brass to strongly, a MILD smoothing with a dremel flex wheel and the issue disappeared.
Using 123's, as LR1955 mentions, will often give you enough inertia to overcome that strong hold by the extractor, but not always.
See if you can cause it manually cycling as LR1955 suggests, if so, its not the gas or buffer system, but something easily rectified.

You seek escape from pain. We seek the achievement of happiness. You exist for the sake of avoiding punishment. We exist for the sake of earning rewards. Threats will not make us function; fear is not our incentive. It is not death that we wish to avoid, but life that we wish to live. - John Galt
