Senior Cup semi-final next up for U's.
A final place against Braintree Town awaits the winners, with Tuesday's match taking place at Concord's Aspect Arena stadium.
The U's battled past Thurrock in the last round of the competition in an eventful match and now face the progressive south Essex side at the semi-final stage.
Having gained promotion last season to the Skrill South, Rangers currently sit in a comfortable twelfth place in the table. They are level on points with the U's neighbours Chelmsford City, but have played four games less than the Clarets.
The match kicks off at 7.45pm on Tuesday, with admission set at £8 adults and £4 concessions, with U16s free.
