The Mk8 is very nice. I didn't see the great quality of the glass until I looked through it in low light conditions. The clarity was amazing then. The FFP thing is taking me a little to get used to, but in reality, as the reticle gets thicker, my target gets more defined. The feeling that the reticle is thick is just me adjusting to the increased zoom. I did notice that the elevation adjustment has hard stops at both ends of the turrets' travel, regardless of the actual position of the internals. Mounted with the scope set at mechanical zero, I was dead on elevation wise, and only 1 mil off on windage at 100 yards.
