It is pretty close to co-witness if not right on, I havent shot it enough to tweak it yet, and the rifle in the back is a remmy 700pss in .308.The conversion looks great. I really like the low profile AIMPOINT. Does it Co-witness?
Also, is that a savage in the back with the Bi-Pod?
lighter, portability, cool factor, closer to spec UMP.SBR, why? I think it looks great the way it is.
