I personally am not a big fan of my v4. Haven't gone NF yet because of the weight, but I think it's inevitable. Other option might be a Trijicon tenmile
Mind me asking what you don’t like about the V4? I have gone through a lot of reviews and yours is the first one I’ve seen that is negative.
There's nothing in particular that is bad, the overall package is just very mediocre for me. I could take it or leave it, good for the price I guess. I don't like the big fat crosshair. The focus is very finicky for me (no, not the parallax) I have a hard time getting a clear picture of the target and the crosshair at the same time. Everybody says they love the glass in the Zeiss but my old non-hd vx6 is heads and tails above the v4 for my eyes. Tracking appears to be pretty good but zero retention is questionable. Clicks are ok not great, the light weight is nice. This weekend we were shooting 1100 and the NX8 on 16 power seemed equal to the Zeiss on 24 power as far as zoom goes. Side by side on 24x it wasn't even close, which I wouldn't expect it to be but still. If I were to do the v4 over again I think I'd go with the 4-16 instead but I have no plans on purchasing another
