Gunter, who had 21 catches for 232 yards last season, earned his Arkansas offer at last week's Advance Football Camp in Fayetteville in part because he ripped off a 4.58 in the 40-yard dash.
He got a chance to work with Razorback tight end coach Barry Lunney, Jr., and in front of Arkansas head coach Bret Bielema.
"It was just about getting up there with Coach Lunney and Coach Bielema, getting to know them better and realizing it was just the place for me," Gunter said. "They have been with me since the start and getting the offer last weekend and coming home and talking it over with my family just made me certain that it is where I need to be."
He becomes the 10th Razorback commitment of a 2016 class that is expected to have 18-22 spots and said his decision is final even if Ole Miss also offers as has Mississippi State.
"They are both great schools, but I am man of word and I won't be looking back no matter how hard they come in," Gunter said. "I believe that Arkansas is the place that I am supposed to be and I will be a Razorback."
Gunter gave Bielema the news about 11 a.m. in a phone call.
'"Coach Bielema let me know that they were very happy to have me as a part of the program and that he and Coach Lunney were very excited about adding me to their list of commits." Gunter said. "My family and I are very excited to be a part of what they are building there at Arkansas.
Madison Central has been a traditional power in Mississippi, but had a rare down year last season.
"We lost some good seniors, but have a lot of great young kids and a new coach and new offense that we are all really excited about," Gunter said. "I think it is going to be a great year and now I can put all my concentration on that now that I know where I am going to college."
