Now the Gers kid hopes he can further enhance his reputation, this time on the world stage, as he looks to star in the dark blue of Scotland.
McKay will line up for Ricky Sbragia's Under-19 side against Sweden tonight as he bids to take his impressive domestic showings into the international arena.
The winger's cap call is a deserved recognition for his form with Ally McCoist's side this season.
He has been joined in the squad by Murray Park peer Charlie Telfer for the Scandanavian clash and is keen to showcase his talents for his country.
He said: "I joined up with the squad on Sunday night. I was back down the road from Elgin and then met everyone so it was a good weekend.
"It is great that I have been called up to the squad again and I am looking forward to the game with Sweden.
"It is another opportunity for me to play and show what I can do. It proves that I am doing well with Rangers and it is good that the manager is noticing what I have been doing.
"I think I have done well when I have come on or started recently, I just want to keep playing games.
"I am sure it will be a good game against Sweden and it is one I am looking forward to.
"Charlie is in the squad with me as well. It is good that a few of us from Rangers are getting international recognition. There are a few of us coming through."
With Ibrox midfielder Lewis Macleod still sidelined through injury, McKay and Telfer are the only Rangers representatives in Sbragia's 28-man squad, with seven Celtic youngsters earning call-ups.
The U19s have Euro Championship clashes with Belgium, Georgia and England to look forward to in May and McKay is relishing the chance to impress boss Sbragia once more.
The Murray Park graduate said: "He is great to work under, I enjoy coming to join the squad. The training is good.
"I hope I am good enough to keep getting in the squad.
"It is excellent to come away and meet up with the boys and play for your country.
"I prefer it when I can get on the ball and attack teams. We need to do what we are good at rather than worrying about what the other team can do and playing to try and stop them.
"Hopefully I can keep progressing and keep making my way up the levels. I am still young and I know I need to keep working hard.
"I will just keep taking it one step at a time and try to not look too far ahead of myself."
