Gretna survived a first-half scare to knock Cove Rangers out of the Cup.
James Grady had them in front after two minutes, before Kenny Deuchar made it 2-0 after 14 minutes with a low drive.
Visiting striker Gary Clarke curled the ball low past Alan Main in the 32nd minute. However, Derek Townsley headed Gretna further ahead.
A McGuffie penalty kick, Grady's second strike and a 30-yard David Nicholls
strike wrapped up the win and put Gretna through to the third round.
