The Gers crashed out of the League Cup at Station Park last month and return to the Angus town on League One duty.
"We had more than enough chances to win that particular game against Forfar and we didn't do it, which was very disappointing," said McCoist.
"We feel we're going back up now with a stronger squad and the boys who did play in the game there previously will obviously know the surface.
"It's an opportunity for us to continue our good run of league results - nothing more than that - and that is what we aim to do.
"We are looking to get another three league points against a team which knocked us out the League Cup and gave us a sore one - effectively our only one so far this season.
"I don't like the word revenge though. All this game does is gives us a chance against a team which has given us a bloody nose."
That defeat to the Loons apart, it has been a terrific start to the campaign for Rangers and McCoist is eager to keep up their 100% league run.
"Absolutely, that's the challenge for us," he told rangers.co.uk
"Our immediate target is to win three points on Saturday and to keep our good run going, nothing more than that.
"We've started really encouragingly. We've scored 23 goals and the two we've lost have both been wonder goals.
"It's important we keep that going because it has a psychological effect on other teams when you're ruthless in front of goal and being mean at the back."
