Shawn Carlock put a 40 moa rail on my edge. It has a Nightforce 5-22 on top. He said it would allow me to dial 2000 yards for some fun. Everything he has said the gun could do, it does ! If you are not going past 1000 20 will be fine though . I was hammering a 1530 yard gong a few days back, and I know the gun has more range within it. It really depends if you want to stretch the guns potential ?
