In November 2015, Black made his Xfinity Series debut at Texas, driving the No.
15 for Rick Ware Racing.
On January 13, 2016, Black announced he would drive the No.
07 Chevrolet Camaro full-time for SS-Green Light Racing.
He finished nineteenth in his debut season, failing to break in to the top ten in any races.

After starting the 2017 NASCAR Xfinity Series season with SS-Green Light, Black was replaced by Todd Bodine for the Charlotte race in 2017 due to a lack of sponsorship.
Spencer Boyd, Korbin Forrister, Andy Lally, Ryan Ellis and Devin Jones also ran in the 07 when Black could not bring sponsorship.
Boyd took over the ride that Black ran 21 of the 33 races in 2017 for 2018 with funding from Grunt Style.

After losing his ride with Ware in the Cup Series, Black returned with B. J. McLeod Motorsports at Daytona in 2018.
The team failed to qualify along with five other cars.
Black returned to the Xfinity Series sporadically in summer 2018, with Isokern Fireplaces as his sponsor.

In January 2019, it was announced that Black would compete full-time in 2019, driving the No.
07 car for SS-Green Light Racing.

Black began the 2020 season by scoring his first career Xfinity top-ten finish, avoiding late crashes to finish eighth at Daytona.
Despite enjoying a strong start to the year with an average finish of 18.6 across the first five races, he withdrew from full-time racing in late May to help his sponsor and father's business CDA Technical Institute, which was struggling financially due to the COVID-19 pandemic.
