I was hand flying the visual backed up by the RNAV. Approximately a mile outside of [final approach fix] I called for the landing gear. The nose wheel and left main had a green light; but the right main did not. The (gear) door and gear light stayed illuminated. We quickly checked the light and saw that the light worked when tested. I told the Captain that I was going around. We went through the normal go around procedures and the gear went up as normal. ATC gave us vectors. The Captain let the passengers know via the PA system why we went around. I continued to fly and talk to ATC. The Captain told Dispatch through ACARS to call us. They gave us two different frequencies; but none worked. The plane does not have SATCOM and were unable to talk to anyone from the company. Due to fuel we decided to run the checklists and drop the gear manually. Gear came down and were cleared back in to [destination]. We landed without incident.
[Report narrative contained no additional information.]
B757 flight crew reported extending the landing gear with the manual backup method after the right main gear failed to extend.
