Montreal won its third straight, equaling its longest winning streak of the season. The three wins have come at the start of a seven-game homestand.
The Rangers cut their deficit to 4-2 by the end of the second period, but Montreal's Robert Lang scored 49 seconds deep in the third period to end thoughts of a New York comeback.
Carey Price needed to make just 18 saves to get the victory. The Rangers saw their advantage over Pittsburgh cut to four points atop the Atlantic Division.
