I recently got a rabbit full grown, not sure what breed he is though?

It sounds as if you have a rex. How big is he? If he is a big boy, he might be a full rex. If he is smaller, he could be a mini-rex. These are very popular these days. It is difficult to tell without a picture but rexes and mini-rexes come in many colors. Also, you can find a lot of mixed breeds, depending upon where you got him. Those will be harder to identify and one can only guess.
