I took the upper apart today looking at it and discovered that the front end of the op rod got bent. This probably occured after the roll pin went AWOL which more than likely allowed the spigot to slide back and forth and bent the op rod which is probably why it started jamming. The top of the spigot show signs of rubbing on the heat shield from the upper handguard which was probably when it was moving back and forth.
I've emailed ARES to see if I need a RMA # to return it for repair.
