Career
Armstrong was selected for the Lothian Schools XI in 2002 while a pupil at Beeslack High School (Penicuik), along with other Hearts youngsters Jason Thomson, David Gray and Andrew Driver. He joined Hearts from their youth system and tasted his first involvement of senior action when he was named as an unused substitute in their Scottish Premier League match against Dunfermline Athletic on 2 January 2007. He made his debut as a substitute at the same venue on 3 February 2007, as Dunfermline beat Hearts 1–0 in the Scottish Cup.

He joined Cowdenbeath on a season-long loan in July 2007, and was again loaned to Cowdenbeath in the 2008–09 season. On 13 October 2009 the defender left Hearts to return to Cowdenbeath, signing a two-year deal with the side. After six years with the club, Cowdenbeath agreed to terminate Armstrong's contract in November 2015 to enable him to pursue other career opportunities. Shortly after leaving Cowdenbeath, Armstrong signed for Scottish Junior side Edinburgh United.
