Guernsey's Director of Rugby, Jordan Reynolds, has told ITV News they "would be top" of National 3 if they could regularly repeat the standard of performance they produced on Saturday.
The Raiders were in fine form as they beat promotion contenders Westcombe Park 16-13.
A late drop goal from fly-half, Owen Thomas, sealed a dramatic victory for the hosts.
Lewis Hillier and Adam Nixon scored a try in either half to help Guernsey to victory.
They now sit fifth in the National 3 table.
