Did some looking around and didn't see any comparisons between the two. I've owned a 5-25 S&B and am looking at the 3-27 or a ZCO for my NRL22 setup. Obviously the 3-27 is more expensive but is it worth the extra $ compared to a ZCO? The two things that stuck out to me are the MT II turrets having a bit more adjustment and the 10-yard parallax vs the 25 on the ZCO. I wanted to open this up and get thoughts from those of you who have had time on these.
