I'd try a different selector as suggested. The groove or detent stop might not be in spec. Is the flat section flat? Check for casting marks there and in the groove and detent stop.
The other remote possibility is the Geissele trigger tail is too tall and is causing the interference. Read the last reply from the OP.
