Mark Warburton's men are preparing for their first campaign back at the highest level for a number of years after they completed another major step on their journey back to the top by securing the Scottish Championship title last term.
Despite going into the campaign having only played two games for the Light Blues across the previous two years, McKay was a key part of the side that secured promotion, scoring nine goals in all competitions.
And the 21-year-old explained which attribute saw him become an integral member of the squad after ending the previous year with a major question mark hanging over his future.
"I think I'm the same type of player but I think my decision-making got better last season," he told The Scottish Sun.
Despite the upcoming step-up in quality, McKay is hoping this season to bag more goals than the nine strikes he managed last term, and explained how the Gers' targets for the year are straightforward.
"We have a big season coming up and we believe we can challenge for the title. We're Rangers and we're looking to win every competition we go into. Last season I scored nine goals and had 13 assists," he added.
"My target was to get double figures so I was one shy and I want to score more goals this season. When you're scoring people remember you more, the assists go under the radar a bit."
Though Warburton has already made eight new signings this summer, he is yet to add any real depth to his options out wide, which arguably suggests that he has little doubt regarding whether McKay is capable of taking his game to the next level.
And if the youngster is able to do that, then the Light Blues will stand a much greater chance of celebrating their first season back in the top flight by clinching the league crown.
