Britt, who UNC is recruiting to play the ram position, chose the Tar Heels over Kentucky. He also claimed offers from Clemson, Duke, Georgia Tech, Ole Miss, Nebraska, Tennessee and Virginia Tech.
The 6-foot, 187-pound prospect made his first visit to UNC a week ago for Fedora's Freak Show. His lead recruiter on the UNC staff was Chris Kapilovic.
Britt recorded four interceptions and 22 tackles for Newnan High in 2013.
He is UNC's 16th commitment in the 2015 class and first for the ram position.
