The League Two champions have won 19 games in a row and are closing in on a club record 22 as they stroll towards the League One title while maintaining their interest in the Ramsdens and Scottish Cups.
Fourteen successive league victories have lifted them 14 points clear of nearest rivals Dunfermline but manager McCoist remains wary of the threat from a number of teams in the third tier of Scottish football.
Speaking ahead of Saturday's home game against third-placed Ayr United, the Gers boss said: "I don't think that will be the case.
"Every game has the potential for a hiccup from our point of view and as I keep pointing out away games in particular are extremely difficult for us.
"Obviously anything can happen at home as well but I think our away games this year at Forfar, where we lost in the League Cup, and again in the league where we won 1-0, were incredibly tight while we were 3-1 down at Brechin before managing to come back and win 4-3.
"So on the evidence of most of the games, but particularly those away from home, I genuinely don't think it will happen. Obviously, I'd be delighted if it did... but I don't think it will."
One player at odds with his boss is defender Bilel Mohsni who is convinced Rangers can go through the campaign with an unblemished record.
Speaking after the 6-1 defeat of Forfar in midweek, the Frenchman said: "Yes, I think so. It's going to be tough for sure, no game will be easy, but we can do it as we have shown we are strong in defence, midfield and up front."
