I also hunt with a BAR in 30-06 and deer are often running when I use it. I have a 3x9x40mm Burris Fullfield II scope on it. I had a Leupold VX-I in the same size previously but I didn't like it at all and had to send it into Leupold for repair twice. You can read about it in many of my other threads. The Burris is much much clearer and imo just a great scope. I however, would use see through sights if the deer are going to be mostly running. I wish that's what I had used. I'm tempted to add them but don't want to have to re sight in the rifle.
