The Gers are 22 points clear at the top of the Third Division, but McCoist has rejected talk of the title being won.
McCoist has said that there is always "extra pressure" to win at Rangers, which he believes motivates the team.
"Effectively it's not over yet. This is a new squad, and a new team but Rangers teams have always had to go and win games," McCoist told reporters.
"Regardless of opposition or competition there is an extra pressure on this club to win games of football.
"I defy anyone to tell me that's not the case and it will be put to the test in the next few weeks."
McCoist took over as Rangers boss in 2011.
