Front only. The front wall is completely gone. 3 sided only. As soon as I picked it up and shouldered it, it became my favorite rifle. Took it on my 8 dy float hunt for moose and griz last year but it didn't get to speak. It just feels so natural to carry it. It's only the second firearm that I will not sell. The only change that I've made is the bolt peep. Used another shroud and kept the original. I use the leave sights but looking through the peep means that I can actually see them.
