Trippie Redd debuted the song at one of his concerts in March 2019, performing it with Lil Duke. The title of the song references the MAC-10 machine pistol. In an interview with Zane Lowe, Redd talked about his collaboration with Duke and Lil Baby, saying:
<blockquote>Baby was sleep on the couch and Duke was up with me, we were just smoking and vibing then Wheezy came in the studio, I asked him for a beat. I did the chorus, Duke got on it then I woke Baby's ass up told him to record his shit⦠He took damn near 30 minutes but he woke up out his sleep and got that out the way.</blockquote>
